A virtually stemless, broadleaf-evergreen native of central and eastern North America: a basal rosette of rigid, sword-shaped, spine-tipped leaves up to 30 inches long, fringed along the margins with the curly white threads that give the species its name. In early summer a flowering stalk shoots from the center to 5-8 feet, carrying nodding, bell-shaped, creamy-white flowers. Tough enough for poor sandy soil, heat, drought, and salt spray, it earns its keep as architectural structure in dry and seaside gardens.

A tall, bold warm-season annual from Mexico and Guatemala (the "African" name is a misnomer of its European garden history) grown for large, fully double, pompon-like flowerheads in saturated yellow, gold, and orange over strongly aromatic, finely divided foliage. Plants reach 12-48 inches and bloom from early summer to frost in full sun. The petals are edible and used as a culinary garnish and natural dye, and the flowers are the iconic "flor de muerto" of Mexican Day of the Dead. Despite the wide listed zone range it is frost-tender and grown for a single warm season.

A native Southeastern North American semi-evergreen woodland groundcover (Pachysandra procumbens), prized for its blue-green to bronze mottled leaves and fragrant white-to-pinkish bottlebrush flower spikes that open at ground level in late winter to early spring. Unlike the widely planted invasive Asian Pachysandra terminalis, this native spreads slowly by rhizomes into well-behaved clumping colonies, making it a low, restrained groundcover for shaded native plantings.

A fast, suckering native shrub of streambanks and moist thickets across eastern North America, grown for huge flat-topped cymes of tiny lemon-scented white flowers in early summer and the clusters of dark elderberry drupes that follow. Spreads by root suckers into naturalized colonies 5-12 feet tall and wide; the flowers feed butterflies and the showy fruit feeds birds. The raw berries are not eaten fresh — they are cooked into jelly, pie, and wine.

The American elm is the great vase-shaped shade tree that once arched over Main Streets and town commons across eastern North America — a fast, extremely cold-hardy deciduous tree of 60-80 feet whose upright trunk divides into a fountain of high, spreading limbs that meet overhead to form a living cathedral ceiling. That iconic form, and the species' tolerance of wet soil and tough urban conditions, made it the default American street tree for a century. Then Dutch elm disease (DED) — an introduced fungal disease carried by elm bark beetles — swept through in the 20th century and killed the vast majority of mature street and shade elms across the continent. The honest reality for a gardener today is blunt: do not plant the unselected wild species expecting it to survive. If you want the American-elm form, plant a DED-tolerant cultivar bred and selected for resistance — 'Princeton', 'Valley Forge', 'New Harmony', or 'Jefferson' — and say so plainly. Where it does grow, it is fast, hardy to USDA zone 3, and remarkably forgiving of wet ground and city stress.

American germander, also called wood sage, is a widespread North American native perennial in the mint family that runs steadily underground on creeping rhizomes. From early to midsummer it sends up erect, softly hairy stems topped with one-sided spikes of pale pink-to-lavender flowers, each with the distinctive deeply lobed lower lip that gives the germanders their look and makes a generous landing platform for bees. It is a plant of moist open ground - wet meadows, streambanks, ditches, and the edges of thickets - across most of the contiguous United States into southern Canada, which tells you exactly what it wants: sun and a soil that does not dry out. The honest caveat is its vigor: those same rhizomes that fill a bank or a rain garden so readily will also colonize a tidy perennial border and crowd politer neighbors. Site it where it can run, or give it a root barrier, and it rewards you with a long, dependable bee-friendly bloom rather than a maintenance fight.

A rounded, multi-stemmed deciduous shrub native across eastern and central North America, grown for its edible nuts and its season-opening catkins. Showy 2-3 inch yellowish-brown male catkins dangle from bare branches in early spring before the ovate, double-toothed leaves emerge; small egg-shaped edible nuts ripen inside leafy husks by mid- to late summer. Easygoing in average soil and tolerant of clay and black walnut, it suckers into thickets that screen and shelter wildlife.

The only native U.S. holly with both spiny green leaves and bright red berries — an upright, pyramidal, broadleaf evergreen tree that slowly matures to 15-30 feet in cultivation (to 50 feet in the wild). Thick, leathery, deep green leaves bear spiny marginal teeth, and pollinated female trees carry showy red-to-orange drupes that ripen in fall and persist through winter as bird food. This is the classic "Christmas holly" of wreaths and decorations.

A small-to-medium understory tree of dry, rocky eastern-North-American woods, named for its drooping clusters of papery, sac-like seed pods that resemble the fruit of hops. The birch-like, sharply-serrated leaves turn an undistinguished yellow in fall, and reddish-brown male catkins persist on the bare branches through winter. Also called ironwood for its extremely hard, dense wood; tough, low-maintenance, and drought-tolerant once established.

A tough, medium-sized native tree of the eastern and midwestern United States, grown as much for its showy edible orange fruit as for its distinctive thick, dark gray bark broken into rectangular blocks. Small urn-shaped white-to-greenish-yellow flowers open in May and June, and the sweet fruit ripens after frost. Largely dioecious — a female tree needs a male pollinizer nearby to set fruit — and notably drought- and walnut-tolerant once established.

A native canopy tree of eastern North American forests with iconic star-shaped 5-lobed leaves displaying outstanding red-purple-orange fall color, distinctive corky wing-bark on twigs, and spiky round seed pods that famously litter lawns ("gumballs"). The seed pods are the design-defining drawback — Liquidambar is rarely planted in formal landscapes for this reason. Choose seedless cultivars ('Rotundiloba', 'Slender Silhouette') for residential planting.

A massive native deciduous canopy tree of eastern North American floodplain forests producing distinctive mottled white-tan-gray exfoliating bark (the design-defining trait — sycamore bark looks like military camouflage), large palmate maple-like leaves, and persistent spherical seed balls. Among the largest deciduous trees in eastern North America — old-growth specimens exceed 150 feet tall + 10 feet trunk diameter. Site only where massive scale is acceptable.

Angel's trumpet (Brugmansia suaveolens) is a large, soft-wooded shrub or small tree hung with enormous pendulous trumpet flowers — up to 12 inches long, white aging to soft blush, and intensely fragrant in the evening and at night. Native to the Atlantic Forest of south-eastern Brazil (POWO, Kew; Flora e Funga do Brasil), it is now classified Extinct in the Wild by the IUCN and survives only in cultivation, which makes a familiar garden plant quietly remarkable. It grows fast and thirsty in warmth (USDA zones 9b-11b) and is frost-tender, so in cold-winter areas it is grown in a large container and overwintered under cover. The load-bearing warning is its toxicity: EVERY PART IS HIGHLY TOXIC, loaded with tropane alkaloids (scopolamine, atropine, hyoscyamine), and poisonings can be severe or fatal — never plant it where children or pets could reach it.

A native eastern-US deciduous shrub — 'Annabelle' is a sterile-flowered cultivar of smooth hydrangea — with very large white snowball blooms in summer. Blooms on new wood so spring frost cannot destroy the flower display, and serves as the larval host for the hydrangea sphinx moth.

A fast cool-season annual of the mustard family grown for its peppery, mustard-like salad greens — irregular, pinnately-lobed basal leaves in a low rosette, each with 4 to 10 small lateral lobes and a large terminal lobe (Missouri Botanical Garden). First cultivated by the ancient Greeks and Romans and still widely grown across Europe, it is best grown in the cooler spring and fall months rather than summer heat; leaves are harvested young and tender before they turn strong and bitter. Pale-yellow four-petalled flowers with dark brown or purple veins appear in corymbs if plants are left to bloom.

A deciduous Eastern-Asian fruit tree with a rounded, spreading crown that the Missouri Botanical Garden lists at 20-30 feet tall and wide. Oval leaves emerge yellowish-green, mature to glossy green, and turn gold to red in fall; fragrant but insignificant late-spring flowers give way to showy orange persimmons (3-4 inches) that ripen in late fall and may persist on bare branches into winter. Winter hardy to USDA Zones 7-10 and drought tolerant once established.

A long-lived herbaceous perennial vegetable grown for the tender young spears harvested in April and May before they unfurl. Native to Europe and temperate Asia, it grows from a crown that takes 2-3 years to come into production but then yields for fifteen years or more. Spears left uncut grow into airy 3-4 foot summer ferns; the plants are dioecious, and female plants ripen ornamental red berries in late summer.

A clump-forming herbaceous perennial grown for its showy late-season flower heads: masses of tiny star-like flowers borne in flattened cymes 3-6 inches across that emerge rosy pink, deepen to rose-red, and fade to coppery-rust as they die. Gray-green, fleshy, succulent-like leaves form upright clumps to about 2 feet. Easily grown in dry-to-medium, well-drained soil in full sun, it is drought tolerant and attracts butterflies, and its foliage and dead inflorescences persist into winter for added interest.

A long-lived, pyramidal deciduous conifer of southeastern North American swamps, bayous, and riverbanks — same family as the redwoods, but "bald" because it drops its soft, feathery, two-ranked needles each fall after a coppery display. Trunks flare into a buttressed base, and trees standing in water often raise the knobby "knees" that make this species unmistakable. Despite its swamp reputation it grows very well in ordinary, even somewhat dry, upland soil, which makes it a tough, large-scale shade tree for parks, lawns, and rain gardens.

The Mediterranean evergreen whose leathery, glossy dark-green leaves are the bay leaf of the kitchen. Missouri Botanical Garden PlantFinder describes it as a pyramidal, aromatic evergreen tree or large shrub that can reach 60 feet but is usually seen at 10-30 feet and is often pruned to 8 feet or less for garden use. Trees are dioecious: small yellowish-green spring flowers on female plants, if pollinated, give way to single-seeded purple-black berries. Winter hardy only to USDA Zone 8, so it is grown as a clipped container houseplant farther north.

The classic German or common-flag iris — the presumed parent of most modern bearded-iris cultivars, probably native to southern Europe and the Mediterranean and naturalized widely. Each stalk carries up to six large, usually fragrant flowers in spring: three erect lilac standards above three purple falls marked with brown veins, white bases, and the signature yellow "beard." It has no bulb, spreading instead by creeping rhizomes that form large clumps, with sword-shaped basal foliage to about two feet.

The signature grass of the North American tallgrass prairie — a tall, deep-rooted warm-season bunchgrass named "turkey-foot" for its three-parted purplish-red seedheads. Blue-green summer foliage rises 4-8 feet and turns maroon-tan for fall and winter. Deeply drought- and erosion-resistant once established; a larval host for skipper butterflies and cover for two dozen songbird species.

A woody, deciduous flowering shrub in the Hydrangeaceae, native to Japan, China, Korea, and Southeast Asia and long grown as the classic "hortensia" or French hydrangea. NC State Extension describes a rounded shrub 3 to 6 feet tall and wide with large opposite, simple, toothed leaves (4-8 inches long) and big rounded mop-head or flat lacecap flower clusters in late spring and summer in white, pink, blue, or purple. Famously, flower color tracks soil chemistry — acidic soils push the blooms blue and alkaline soils turn them pink. It wants protection from hot afternoon sun and steady moisture, making it a mainstay of shaded foundation plantings and woodland borders.

The largest native cherry of eastern North America — a medium-to-large deciduous shade tree that hangs elongated racemes of small white flowers in spring, then ripens drooping strings of pea-sized fruit from red to near-black in late summer. The fragrant white bloom feeds bees while the fruit is eaten by 33 species of birds and many mammals; it is also a workhorse larval host, supporting the Eastern Tiger Swallowtail and a string of giant silk and sphinx moths. Every part except the ripe fruit is cyanide-bearing and toxic.

A native eastern + central North American thicket-forming shrub producing arching thorny canes + clusters of large sweet black berries in mid-to-late summer. Among the most important wildlife fruit producers in eastern forests — birds, mammals, + insects all depend on the fruit. Like raspberry, biennial-caned (primocane year 1, fruits in year 2 as floricane, then dies back). Spreads via root suckers + tip-rooting cane tips; manage with annual pruning.

A medium-to-large native shade tree of central and eastern North America, reaching 50-80 feet with an ovate-rounded crown and large, asymmetric heart-shaped leaves. In June it carries pale-yellow, intensely fragrant flowers on pendulous cymes — each cluster hung from a distinctive strap-like leafy bract — that ripen into pea-sized nutlets. The fragrant June bloom is a premier nectar source: Missouri Botanical Garden lists it as attracting bees and butterflies, and the Lady Bird Johnson Wildflower Center flags it as having special value to both native and honey bees.

Once the dominant canopy hardwood of the eastern United States forest — an estimated four billion trees, prized for fast growth, rot-resistant timber, and an enormous annual crop of sweet edible nuts that fed people, livestock, and wildlife alike. In the early 1900s an introduced Asian fungus, chestnut blight (Cryphonectria parasitica), swept through and functionally destroyed it: by the 1950s the species was effectively extinct as a mature forest tree. Surviving root systems still send up sprouts from old stumps, but the blight almost always girdles and kills them before they can grow large enough to flower and reproduce. The honest reality for a gardener is that you cannot reliably grow a mature wild-type American chestnut today. The realistic paths are blight-resistant backcross hybrids from The American Chestnut Foundation or transgenic blight-tolerant lines still being deployed — not a pure wild seedling, which the blight will almost certainly kill.

A small native deciduous tree (or thicket-forming, suckering shrub) of eastern and central North America, grown for clouds of fragrant white 5-petaled flowers that open in March before the leaves and for the edible red plums that follow in early summer. It forms a broad, spreading crown with attractive dark reddish-brown twigs that sometimes carry thorny lateral branchlets. A documented larval host for swallowtails and other butterflies, with flowers of special value to native, bumble, and honey bees.

A native bramble (cane) producing red aromatic edible fruit in summer or fall (depending on summer-bearing vs everbearing cultivar). Self-pollinating; spreads vigorously by root suckers + tip-rooting canes. NC State documents extensive Lepidoptera + small mammal + bird wildlife value alongside the edible fruit role. Site where the spreading habit is welcome — naturalized colonies form in sun-exposed open ground.

An upright, clump-forming perennial of the mint family native to the upper Midwest, Great Plains, and into central Canada, named for its anise-scented foliage. From June through September it carries dense terminal spikes of lavender-to-purple two-lipped flowers above square stems and opposite, toothed leaves. The Lady Bird Johnson Wildflower Center flags it as a nectar source with special value to native bees, bumble bees, and honey bees, and it also draws butterflies and hummingbirds.

The domesticated orchard apple — a deciduous Rosaceae tree grown for its showy, edible fruit and fragrant April blossom of five white-to-pink petals around a ring of yellow stamens. Not native to North America (the genus Malus spans Europe, Asia, and North America, but the cultivated apple is an Old World hybrid lineage). Almost all varieties are self-incompatible: a second, different apple cultivar blooming at the same time must be nearby for fruit to set, and trees are grown on dwarf, semi-dwarf, or standard rootstocks that decide final size.

A small deciduous Rosaceae fruit tree grown for its golden-orange, red-blushed drupes — fragrant, showy, edible, and ripening in summer. Fragrant white flowers (pink in bud) open in early spring before the foliage, two weeks ahead of peaches. That early bloom is also its weakness: the flowers are extremely susceptible to frost injury, so apricots are notoriously hard to crop reliably outside sheltered sites.

A native central + eastern US perennial with intensely aromatic foliage when crushed and dense clouds of small blue-purple flowers in late fall — often the latest-blooming aster in the eastern flora. Drought + clay tolerant; among the toughest native fall pollinator plants.

A native eastern + central North American multi-stemmed deciduous shrub with dentate (toothed) foliage, white spring flower clusters, blue-black drupes, and reliable fall color. Especially valued for wildlife — among the most-cited native shrubs for fall-migration bird forage.

Asiatic hybrids are the easiest lilies to grow and among the first to bloom — rigid, unbranched 3-4 foot stems carry large, mostly upward- and outward-facing flowers 4-6 inches wide in nearly every color but blue, often with dark basal spotting. The flowers are showy and good for cutting but, unlike most other lily groups, usually have little or no fragrance. Every part of the plant is dangerously toxic to cats.

A drought-and-flood-tolerant native shrub of eastern North America with brilliant three-season interest — spring white-pink flowers, glossy black antioxidant-rich late-summer berries, and brilliant wine-red fall foliage — plus an extraordinarily wide cold-hardiness range (USDA 3a-8b). The berries are astringent fresh but the basis of a small but growing commercial industry (juices, wines, jams, supplements) for their exceptionally high anthocyanin content. Spreads by suckers; site where colony formation is welcome.

Black elder (Sambucus nigra) is a fast, tough, wildlife-rich deciduous shrub native across Europe, north Africa and western Asia (POWO). It earns its place twice a year: broad flat creamy-white flower umbels scent the garden in early summer, then drooping clusters of small black berries ripen in late summer to feed birds in quantity. RHS gives the ornamental forms (e.g. "Black Lace") the Award of Garden Merit and rates the species fully hardy (H6). It is also one of the classic foraging shrubs — the flowers and the COOKED ripe berries are much-used for elderflower cordial and for elderberry syrup, wine and jam. The honest catch is real: the raw berries, and the leaves, bark, stems and roots, are toxic (cyanogenic glycosides) and cause nausea and vomiting, so berries must always be cooked and never eaten raw or unripe. Vigorous to the point of suckering and seeding about, elder is a wildlife and hedgerow plant first, an ornamental second.

A native eastern North American spring ephemeral wildflower with pristine white 8-12-petaled flowers in early spring (often the first major forest-floor wildflower of the year) wrapped by a single rounded glaucous leaf. Disappears by midsummer to underground rhizomes. The red rhizome sap was historically used by Indigenous peoples as a dye and ceremonial paint.

A native vervain of eastern and central North American wet meadows, stream banks, and rain gardens — a rough, clump-forming perennial with stiff, square hairy stems that branch above into candelabra-like spires. Slender, pencil-like spikes carry tiny purplish-blue tubular flowers that open a few at a time from the bottom up over a long July-to-September bloom. Attracts hummingbirds and butterflies and carries Special Value to Native Bees.

A large, hairy, clump-forming North American native perennial of wet meadows, low woods, stream banks, and prairies. Its most distinctive feature is the perfoliate foliage — pairs of wrinkled, opposite, lance-shaped leaves whose bases fuse around the hairy stem, so the stem appears to pass through the leaf. From July to September, flat-topped clusters of small, fluffy white flowers feed a wide range of bees, butterflies, and other pollinators, while all parts of the plant are toxic and bitter.

A deciduous shrub grown almost entirely for its explosion of yellow four-lobed flowers that line the bare arching stems in early spring, before the leaves emerge. A garden hybrid of two Asian species (Forsythia suspensa × F. viridissima) — not native to North America. Missouri Botanical Garden describes it as a "one-season wonder" that fades into the background after bloom, so it earns its place as a late-winter color signal rather than a four-season anchor.

One of the most majestic native North American oaks — a slow-growing, long-lived member of the white oak group that the Missouri Botanical Garden lists at 60-80 feet (occasionally to 150) with an equally broad, rounded crown. Named for its large acorns whose cups are fringed with a mossy, bur-like scale near the rim. Notably drought- and clay-tolerant, it ranges from southeastern Canada through the central United States, and may take up to 35 years to bear its first acorn crop.

A small native tree with white spring flowers, edible summer berries, and copper to red fall color.

A large, rounded, multi-stemmed broadleaf evergreen shrub of the southern Appalachians — typically 6-10 feet tall (rarely to 20) with glossy dark green leaves and showy compact terminal trusses of 15-20 funnel-shaped lavender-pink flowers in mid to late spring. Native from Virginia to Kentucky south to Georgia and Alabama, where it forms dense thickets on rocky high-elevation slopes and ridges. Prefers cool summers, acidic moist-but-well-drained soil, and part shade; all parts are highly toxic if ingested.

A tough, aromatic garden hybrid (Nepeta racemosa x N. nepetella) that forms a low, spreading mound of scalloped gray-green leaves topped by raceme-like spikes of two-lipped lavender-blue flowers from late spring into fall. Sterile and clump-forming rather than weedy, it shrugs off heat, drought, and deer, draws bees all season, and is mildly attractive to cats — a workhorse for border fronts, edging, and dry sunny sites.

A tough, deep-rooted perennial in the daisy family (Asteraceae), grown for both its sky-blue summer flowers and its many edible uses. Native to Europe and now widely naturalized along roadsides and in fields across North America, chicory sends up wiry, branching stems 3-4 feet tall from a long, stout taproot. The ray flowers are a clear sky-blue (occasionally white or pink), opening in the morning and closing again by midday. The same plant gives three classic harvests: bitter young leaves for cooking and salads, a roasted taproot used as a caffeine-free coffee substitute or additive, and forced, blanched shoots known as 'chicons' (Belgian endive / witloof). It thrives on poor, dry, sunny ground where pampered plants would not, and its deep taproot makes it genuinely drought-tolerant once established.

A massive, fast-growing deciduous woody vine from China, famous for its mid-spring curtains of fragrant, lavender-to-violet (sometimes white) pea-like flowers hanging in long, dense racemes that open all at once before the leaves fully expand. The display is genuinely spectacular — but Chinese wisteria is one of the most aggressive ornamental vines in cultivation, and across the southeastern United States it has escaped gardens to become seriously INVASIVE, twining up and GIRDLING trees, smothering whole canopies, and forming dense thickets that crowd out native plants. It is extremely vigorous, twines counterclockwise with great force, and demands very sturdy support, hard annual pruning, and constant vigilance to keep it off houses, gutters, and trees. The seeds and pods are TOXIC if eaten. For most gardeners the honest recommendation is to plant the native American wisteria (Wisteria frutescens) instead — it gives a similar flowering effect with a fraction of the aggression and none of the invasive ecological cost.

An evergreen woodland perennial grown for one of the most prized feats in the garden — large, outward-facing, pure-white bowl-shaped flowers that open in the depths of winter, often around Christmas, ageing to soft pink as they fade. Leathery, dark, finger-divided leaves persist year-round beneath the blooms. Helleborus niger is native to the mountains of central and southern Europe — the Alps and the northern Apennines (POWO, Kew) — and it brings those origins to the garden: it wants cool, humus-rich, well-drained soil in part shade, dislikes disturbance once settled, and can be slow to establish. The Royal Horticultural Society gives it the Award of Garden Merit and rates it fully hardy (H6). Honest caveat: every part of the plant is toxic if eaten (cardiac glycosides) and the sap can irritate skin — wear gloves when handling — which, as a side benefit, makes it thoroughly deer-resistant.

A tender perennial from Madagascar grown across temperate North America as a heat-loving summer annual — a mounding 6-18 inch plant in the dogbane family covered in flat five-lobed phlox-like flowers from June to frost. The species blooms rosy-pink to red with a darker mauve throat, and it shrugs off the hot, humid weather that wilts most bedding plants. Every part of the plant is poisonous: it is the natural source of the vinca alkaloids used in chemotherapy.

A frost-tender broadleaf evergreen tree of the laurel family, native to Mexico and Central America and grown across the tropics and subtropics for its buttery, pear-shaped fruit. Glossy dark-green elliptic leaves 4-8 inches long clothe a tree that reaches 30-60 feet, hung with greenish-yellow flower panicles that give way to large single-seeded berries. Hardy only in USDA zones 10-12 — north of that it is an indoor curiosity easily sprouted from a pit, but one that rarely fruits.

A giant herbaceous perennial from Southeast Asia and the principal wild ancestor of most cultivated dessert bananas. What looks like a trunk is a 'pseudostem' — tightly rolled leaf sheaths — topped by a fountain of huge, paddle-shaped leaves that can run 6-10 feet long, giving an instant tropical effect. In frost-free climates (USDA zones 10a-11b) an established clump produces a drooping flower spike and a hanging bunch of edible fruit, then that pseudostem dies and is replaced by a sucker from the base. It is frost-tender: everywhere colder it is grown as a bold container or greenhouse foliage plant that is overwintered indoors and rarely, if ever, fruits.

A clumping, multi-stemmed evergreen perennial from South Africa, grown for its unmistakable crane-head flowers — a horizontal green-and-pink spathe from which bright orange sepals and vivid blue petals emerge like the crest of an exotic bird. Bold, paddle-shaped blue-green leaves on long stalks form a 3-4 foot fountain of foliage. Winter hardy only in USDA zones 10-12 (frost-free subtropics); everywhere colder it is grown as a houseplant or summered-out container plant. It blooms reliably only from a well-established, somewhat crowded clump, so patience is the key to flowers.

The true Christmas cactus — the hybrid Schlumbergera x buckleyi — a long-lived epiphytic holiday cactus grown indoors almost everywhere for its arching, segmented stems and its rose-to-magenta flowers that open in mid-winter, around Christmas. It is worth getting the identity right, because most plants sold and labeled as 'Christmas cactus' are actually the Thanksgiving cactus, Schlumbergera truncata. You can tell the two apart by the edges of the flat stem segments and by when they bloom: the true Christmas cactus has rounded, scalloped segment margins and flowers a few weeks later, in mid-winter, while the Thanksgiving cactus has sharp, claw-like teeth and blooms from late fall into early winter. Unlike a desert cactus, this is a forest epiphyte that grows on tree branches in the Atlantic coastal forest of southeastern Brazil, so it wants bright indirect light, a free-draining mix, sparing water, and — to set its buds — cool nights and short days. A reassuring point that sets it apart from many houseplants: it is non-toxic to cats and dogs.

A tender tropical foliage plant grown for its boldly patterned, toothed leaves rather than its flowers — magenta, maroon, lime, and copper combinations in almost every color of the spectrum except true blue. A frost-sensitive perennial native to tropical and subtropical Asia and northern Australia, it is grown almost everywhere outside USDA zones 10-11 as a warm-season annual, container plant, or houseplant. The small blue-to-white nettle-like flower spikes are insignificant and are usually pinched off to keep the plant compact and the foliage at its best.

A tropical evergreen tree from the lowland rainforests of western and central Africa, grown almost everywhere else as a dramatic indoor specimen for its huge, glossy, fiddle- (or violin-) shaped leaves with bold sunken veins. In its native habitat it becomes a 40-foot tree, but as a houseplant or patio container plant it is typically kept to a single upright 6-15 foot trunk topped with a sculptural rosette of leaves. Winter-hardy only in the frost-free subtropics (USDA zones 10-12); everywhere colder it is a houseplant. It is famously fussy: it wants bright, steady light, even moisture, warmth, and — above all — to be left in one spot, dropping leaves in protest at cold drafts, moves, or erratic watering.

A tender warm-season culinary herb native to tropical Africa and Asia; grown as an annual in most US climates for fragrant edible leaves and as a kitchen-garden staple. Sweet basil is the species behind Genovese, Thai, and most ornamental purple basils.

A giant evergreen relative of the banana from coastal eastern South Africa, grown for its enormous, gray-green, paddle-shaped leaves and its dramatic white-and-blue, crane-like flowers. Honesty first: in frost-free climates (USDA zones 10a-11b) it forms a fan of multiple woody trunks and reaches 20-30 feet tall, with large bird-of-paradise blooms held in dark, boat-shaped bracts up in the canopy. It is frost-tender, so everywhere colder it is grown as a big container or indoor foliage plant — kept far smaller by the pot and rarely, if ever, flowering. The whole plant is a mild irritant if eaten, with the seeds more so, so it is best kept away from curious pets and children. It is grown above all for bold, tropical, architectural foliage rather than for its flowers in most gardens.

A spectacular flowering tree from the Atlantic Forest of eastern Brazil, where it is known as quaresmeira, grown for repeated flushes of intense royal-purple flowers borne in showy panicles over glossy, ribbed, dark-green leaves. The bloom can recur several times a year, smothering the canopy in violet and dropping a carpet of purple petals beneath. Honesty first: this is a frost-tender tropical tree (Melastomataceae), native to the Atlantic Forest of eastern Brazil (POWO, Kew; Flora e Funga do Brasil), hardy only in roughly USDA zone 10 and warmer, for tropical and frost-free subtropical gardens. It grows fast but the wood is brittle and breakable in wind, so it is a short-to-medium-lived showpiece rather than a long-term structural tree. A taxonomic note worth carrying: the accepted name is now Pleroma granulosum (POWO, Kew; GBIF), with Tibouchina granulosa kept as a widely-used synonym — the name most gardeners and nurseries still use. Its flowers are buzz-pollinated, releasing pollen only to native bees that vibrate the anthers.

A tropical, frost-tender pepper grown for some of the hottest fruits in the kitchen garden — this single species includes the habanero, Scotch bonnet, ghost (bhut jolokia), and Carolina Reaper. Native to the Americas (the Amazon basin and the Caribbean), Capsicum chinense is a true perennial only in frost-free zones 10-11; across nearly all of North America it is grown as a heat-loving warm-season annual. It needs a long, hot season to ripen its lantern-shaped fruits, and the capsaicin in those fruits is potent enough to burn skin and eyes, so it rewards a sunny spot and careful handling.

The "busy lizzy" — by Missouri Botanical Garden's account "the most popular annual bedding plant in the U.S. today," prized for non-stop flowering in shade where most annuals sulk. A succulent-stemmed tender perennial from East Africa (Tanzania, Mozambique), it is grown as an annual everywhere but USDA zones 10-11, mounding 6-24 inches tall and covering itself with showy, slender-spurred, five-petaled flowers in pink, rose, red, lilac, purple, orange, white, and bicolors from June to frost. Worth knowing before you plant a whole bed: the species is susceptible to impatiens downy mildew (Plasmopara obducens), which can collapse a planting.

A frost-tender broadleaf shrub from tropical America grown across most of North America as a heat- and drought-tough annual bedding plant, container subject, or houseplant. Dense 2-inch hemispherical clusters of tiny five-lobed flowers — often white, yellow, orange, red, and purple mixed in the same head — bloom July to frost and draw hummingbirds and butterflies. The rough, aromatic foliage and every other part are toxic if eaten, and the species has escaped cultivation to become invasive along the warm-winter southern US coast.

A tender perennial from New Guinea grown almost everywhere in North America as a warm-season annual, prized for non-stop bright bloom in part shade — and, unlike common impatiens, in considerably more sun. It mounds 6-24 inches tall and 18-36 inches wide, carrying large, flat, five-petaled flowers in coral, salmon, pink, red, orange, lavender, and white above bold, often bronze-tinted dark foliage. Its real selling point is honest and practical: Impatiens hawkeri is resistant to impatiens downy mildew (Plasmopara obducens), the disease that collapsed plantings of Impatiens walleriana, making it the dependable shade-to-part-sun bedding plant where the common species can no longer be trusted.

A fast-growing, short-lived tropical fruit plant of tropical-American origin — POWO (Kew) records a neotropical origin around southern Mexico and Central America, and it is now grown throughout warm Brazil as the mamao, its presence recorded in Flora e Funga do Brasil. Although it looks like a small palm-like tree, it is really a giant single-stemmed herb: a soft, hollow, unbranched trunk topped by a crown of large, deeply-lobed, long-stalked leaves, with clusters of melon-like fruit borne directly against the trunk. It is one of the fastest food plants you can grow, often fruiting within a year of sowing, but it is short-lived and frost-tender (hardy in the ground only in roughly USDA zones 10a-11b). HONESTY: it is usually DIOECIOUS — most plants are either male or female — so you generally need a female plus a male (or one of the hermaphrodite forms) for the female to set fruit. The ripe fruit is edible and excellent fresh, but the unripe fruit and all the green parts ooze a white latex (papain) that can irritate skin and should not be eaten raw.

The garden petunia is a complex Brazilian-derived hybrid in the nightshade family, grown almost everywhere as a warm-season bedding annual for its funnel-shaped, often fragrant flowers in nearly every color except true brown and black. Missouri Botanical Garden ranks it second only to impatiens in annual bedding-plant sales, prized for non-stop bloom from late spring until frost. It is a tender perennial hardy only in USDA Zones 10-11, so most of North America treats it as a single-season annual.

A terrestrial bromeliad grown for its sweet, golden, edible fruit — the abacaxi of warm Brazil. POWO records it as South American in origin, its precise wild range obscured by ancient domestication, and Flora e Funga do Brasil documents Ananas in Brazil. The plant forms a low rosette of stiff, sword-shaped leaves, many forms armed with sharply toothed margins, from the centre of which a single stout stem rises bearing a dense cone of small purple flowers. Those flowers fuse together into the familiar multiple fruit (a syncarp), topped by a leafy crown that can itself be rooted to grow another plant. HONESTY: this is a frost-tender tropical, hardy in the ground only in roughly USDA zones 10a-11b, and it is slow — a plant takes well over a year from planting to a ripe fruit. Commercial clones are largely self-incompatible and, kept isolated from other clones, set the seedless fruit prized in the kitchen.

A spectacular semi-deciduous tropical tree, native from southern Mexico through Central America to northern South America (POWO, Kew) and widely planted across tropical Brazil as an ipe-rosa (recorded in Flora e Funga do Brasil). It is one of the great flowering street and park trees of the tropics: in the dry season it drops most of its leaves and then erupts into clouds of pink-to-pale-mauve trumpet-shaped flowers on bare branches before refoliating, blanketing the crown and dropping a carpet of petals below. A fast-growing, deep-rooted tree reaching roughly 40-80 feet, it forms a broad, rounded crown of palmately compound leaves and is grown purely as an ornamental shade and flowering tree. HONESTY: it is frost-tender, hardy in the ground only in USDA zones 10a-11b, and needs a tropical or frost-free subtropical climate; everywhere colder it cannot survive outdoors year-round. Once established it is fairly drought-tolerant thanks to its deep roots, but it is a large tree that needs real space.

A large, spreading tropical tree from sub-Saharan Africa, famous for the enormous grey, sausage-shaped fruits that dangle on long cord-like stalks beneath its rounded crown. Honesty first: where it is hardy (USDA zones 10a-12b) it grows into a 30-60 foot evergreen-to-semi-deciduous shade tree, and at night it opens large, maroon, foul-smelling, cup-shaped flowers that are pollinated by bats. The fruits are the headline and the hazard — they can reach about 2 feet long and weigh several pounds, and a falling fruit can genuinely injure a person or dent a car, so it must never be sited over patios, walks, or parking. The raw fruit is toxic and purgative to humans; it is used only after careful processing in traditional medicine and skincare, never eaten raw. It is frost-tender and strictly a warm-climate specimen tree, not a temperate-garden plant.

A tender perennial herb in the aster family (Asteraceae), grown for its remarkably sweet leaves — per the Missouri Botanical Garden PlantFinder the foliage contains glucoside compounds and tastes notably sweeter than sugar with no calories, which is why it is also called sweetleaf. Native to Brazil and Paraguay, it forms weak, floppy stems to 1-2 feet tall clothed in oblong, toothed leaves, with small showy white flowers in July and August. Winter hardy only in USDA zones 10-11; across most of North America it is grown as an annual or overwintered indoors, and leaves are best harvested before flowering.

A bold tropical aroid from the rainforests of southern Mexico through Panama, grown almost everywhere outside the frost-free tropics as a foliage houseplant. It is a climbing epiphyte: it sends adventitious aerial roots to scramble up tree trunks, and its huge glossy heart-shaped leaves develop the deep cuts and oval holes (fenestrations) that give it both common names. Mature plants in the tropics flower with a creamy aroid spathe and produce a cone-like fruit that is edible only when fully ripe. Indoors it rarely flowers and is prized purely for its dramatic, architectural foliage.

A long-lived epiphytic cactus from the Atlantic coastal forest of southeastern Brazil, grown indoors almost everywhere for its arching, segmented stems and its showy late-fall and winter flowers in hot pink, magenta, red, orange, salmon, or white. It is the plant most often sold and labeled as a 'Christmas cactus,' but the confusion is near-universal and worth getting right: this is the Thanksgiving, crab, or claw cactus, with sharp, claw-like teeth on the edges of its flat stem segments and a bloom season that runs from late fall into winter. The true Christmas cactus is a different plant, the hybrid Schlumbergera x buckleyi, which has smooth, rounded segment margins and blooms a few weeks later. Unlike a true desert cactus, it is a forest epiphyte that grows on tree branches in dappled light, so it wants bright indirect light, a free-draining mix, sparing water, and — to set its buds — cool nights and short days. A reassuring point that sets it apart from many houseplants: it is non-toxic to cats and dogs.

A tender perennial grown almost everywhere as a warm-season bedding annual, prized for blooming reliably from June to frost in white, pink, red, and bicolor. Its thick, waxy dark-green-to-bronze leaves minimize water loss, giving it real tolerance for hot, humid summers. Compact and mounding at 6-12 inches, it is a workhorse edger and container filler in sun-dappled part shade.

A large tropical evergreen tree from Asia and northern Australia, where it can reach 30 feet or more with a broad, rounded crown of arching, weeping branches clothed in glossy, pointed, 2-4 inch leaves. Across most of the world, though, it is grown as one of the most popular indoor trees, kept to 5-10 feet in a pot and valued for its graceful weeping form and dense, shiny foliage. It is hardy outdoors only in frost-free climates (USDA 10a-12b); everywhere colder it is a houseplant. Its single most famous trait is dropping its leaves dramatically whenever it is moved, drafted, over- or under-watered, or otherwise stressed - a habit new owners often mistake for death. The milky white latex in its stems and leaves is mildly toxic if eaten and is a well-known skin and airborne allergen.
