Flint Hills tallgrass prairie

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 to 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 1 to 4 feet 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 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 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 dense, conical-to-narrow-pyramidal evergreen tree native to eastern and central North America, prized as a screening and foundation conifer. Flat, fan-like sprays of scale-like, aromatic yellow-green foliage clothe the tree from the ground up, and red-brown bark exfoliates on mature trunks. Wild trees can reach 40 to 60 feet but cultivated plants typically stay near 20 to 30 feet; small urn-shaped cones and dense evergreen cover make it valuable food and shelter for birds.

A medium-to-large native shade tree of central and eastern North America, reaching 50 to 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.

American beautyberry (Callicarpa americana) is a loose, open, arching deciduous shrub of the southeastern and south-central United States, grown almost entirely for one spectacular autumn trick. Through summer it is a quiet green background plant, carrying small clusters of pink-to-lilac flowers tucked into the leaf axils. Then, from late summer into fall, those clusters ripen into tight whorls of vivid magenta-purple berries that wrap right around the stems at every leaf joint, so the arching branches look strung with beads. Songbirds strip them through fall and early winter. It is an easy, fast-growing, forgiving native that asks for little: full sun to part shade, ordinary well-drained soil, and room to arch. Site it where the fall berry show can be seen, because in leaf and flower it is plain, and in fruit it is one of the most distinctive shrubs you can grow.

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 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 to 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 to 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 stately, classic tall border perennial - the parent of the great Elatum-hybrid delphiniums - grown for towering, densely packed spires of spurred flowers, most famously an intense pure blue (also purple, white, or pink), each bloom centred on a contrasting tuft of petals known as the "bee." It rises on tall hollow stems above deeply palmate-lobed leaves and flowers in early to mid summer. Magnificent but high-maintenance and load-bearing in its honesty: the tall spikes need staking and shelter from wind, the plant is hungry, thirsty, fairly short-lived, a slug magnet on its emerging shoots, and it dislikes hot, humid summers, performing best in cool-summer climates. It is also HIGHLY TOXIC in all parts (diterpenoid alkaloids), and the sap can irritate skin - which is also what makes it reliably deer-resistant. POWO (Kew) places it native to the mountains of Europe across to Siberia and central Asia; RHS rates the species fully hardy (H7) and has given the Award of Garden Merit to many of its hybrids.

Colorado blue spruce (Picea pungens) is a narrow, stiffly pyramidal conifer from the central and southern Rocky Mountains, and the source of nearly every silver-blue evergreen in cultivation. The colour is real and is the reason it is planted: the needles carry a waxy bloom that reads anywhere from grey-green to an almost metallic pale blue, sharpest on selected cultivars. In its native range, between roughly 6,000 and 11,000 feet from Wyoming and Idaho south to Arizona and New Mexico, it is a cool-climate mountain tree of moist stream sides and canyon bottoms. Planted far outside that range - which is where most people meet it - it is one of the most reliably disappointing conifers in the eastern United States, where humid summers bring on needle cast and cytospora canker and a fifteen-year-old specimen often loses its lower branches and never recovers them. It is also planted far too small: the nursery pyramid becomes a 30-to-60-foot tree. Given cool air, full sun, room, and honest expectations, it is superb and long-lived.

Common laburnum, or golden chain tree (Laburnum anagyroides), is a small deciduous tree of the mountains of central and southern Europe, growing 15 to 30 feet tall and famous for one spectacular moment: in May and June it drips with long, fragrant, pendulous chains of golden-yellow pea flowers. It is a classic ornamental - the material of the great laburnum arches - but it comes with a serious, load-bearing warning. Every part of the tree is poisonous. NC State rates its poison severity High and warns it "may be fatal if eaten"; the seeds, held in pea-like pods that children can mistake for edible peas, are the most dangerous part. Plant it for its beauty with clear eyes about siting it away from where children and livestock browse.

A large, graceful evergreen conifer of cool, moist eastern North American forests, reaching 40 to 70 feet with a dense, pyramidal-to-conical crown and arching, feathery branches that sweep nearly to the ground. Short, flat, dark-green needles with two white bands beneath line slender twigs, and small drooping cones hang from the branch tips. The most shade-tolerant of the eastern conifers, it makes an elegant specimen or tall screen where soils stay consistently moist and cool. HONESTY: across much of its eastern range it is under serious, frequently lethal attack from the hemlock woolly adelgid (Adelges tsugae); do not plant it as a long-term backbone tree without committing to monitoring and treatment.

Fraser fir (Abies fraseri) is an evergreen fir endemic to the high-elevation southern Appalachian Mountains of southwestern Virginia, western North Carolina, and eastern Tennessee, where it grows only on cool, moist, fog-drenched summits above roughly 4,000 feet. It is a modest-sized conifer, usually 30 to 50 feet tall with a narrow, spire-like crown, soft flattened dark-green needles with silvery-white undersides, and erect purple cones whose papery bracts curl back over the scales. It is best known as one of the most popular Christmas trees in North America, prized for its balsam fragrance, soft non-prickly needles, and excellent needle retention. The honest catch is that it is a true mountain plant: it needs cool summers, high humidity, and acidic, evenly moist but well-drained soil, and it does poorly in the heat and humidity of the lowland South, roughly anywhere below or south of USDA zone 7. Its wild stands are also in serious trouble - the introduced balsam woolly adelgid has killed the great majority of mature wild trees since the mid-20th century, and the species is assessed as Endangered.

Grand fir (Abies grandis) is one of the great trees of the Pacific Northwest and a poor choice for most gardens, and those are the same fact rather than two: it is built for cool, wet, deep-soiled maritime ground and it is built enormous. Missouri Botanical Garden gives it 100 to 250 feet with a 4 to 6 foot trunk, says it performs poorly in most areas of the eastern United States, and states flatly that it is not recommended for planting south of USDA Zone 6. It is also fast - the coastal form can put on more than 5 feet a year while young - so the mistake compounds quickly, and it is not a durable tree in return: historically it reached nearly 300 years, but 100 is more typical under modern stress. Its bark is thin and it cannot seal a wound with pitch, so fire scars, pruning cuts and logging damage open the trunk to heart rot, and east of the Cascades a trunk carrying Indian paint fungus is rotten inside whether or not the crown looks it. Balsam woolly adelgid, bark beetles, root rot and needle rust are all on Missouri Botanical Garden's problem list, and western spruce budworm epidemics killed grand fir at scale in the eastern Cascades and the Blue Mountains in the late twentieth century. What is genuinely wonderful about it belongs on the label too. The needles are flat, blunt and laid in two neat horizontal ranks like the teeth of a comb, and along one side of a twig they alternate short, long, short - a sawtooth that white fir rarely shows and the quickest way to name the tree. Crushed, they smell strongly of tangerine, which is why it is also called stinking fir, and no other fir in this group smells like it. The cones stand UPRIGHT on the upper branches and never fall whole; they break apart on the tree in autumn and leave a bare spike standing on the branch, which is the single cleanest way to separate any Abies from a spruce or a pine.

Japanese holly is a dense, small-leaved evergreen shrub native to Japan, Korea, eastern China, and adjacent regions of eastern Asia, widely grown as a boxwood substitute for formal hedging and topiary. It tolerates heavy shearing well and thrives in acidic soils in a range spanning USDA zones 5b-8b. The honest catch is twofold: the glossy black berries are toxic to humans and pets (a genus-wide trait of Ilex), and the species is listed as invasive in parts of the eastern United States, where bird-dispersed seedlings colonise native woodland edges.

Korean fir (Abies koreana) is a compact, slow-growing evergreen fir from the high mountains of southern South Korea, where it is confined to cool, misty summits, most famously Hallasan on Jeju Island. In gardens it makes a dense, neat, conical small tree, usually 15 to 30 feet over many years, with short broad needles that are dark green above and marked beneath with two vivid white bands, so the whole tree flashes silver when the wind turns the foliage. Its signature is the cones: erect, cylindrical, and an intense violet-blue when young, and unusually it bears them freely even on young plants only a few feet tall, which is why it is one of the most collected ornamental firs and holds the RHS Award of Garden Merit. The honest catch is that it is a true mountain conifer: it wants cool summers, steady moisture, and acidic, well-drained soil, and it resents heat, drought, and urban pollution, so it disappoints in hot lowland gardens south of about USDA zone 7. It is also Endangered in the wild, where warming is widely blamed for pushing its shrinking high-altitude stands, most visibly on Jeju, further up the mountains.

A large, fast-growing European evergreen conifer reaching 40 to 60 feet (sometimes far taller in age) with a broadly pyramidal crown and a distinctive habit: the main branches sweep upward or outward while the slender secondary branchlets hang straight down in graceful, drooping curtains. Stiff, four-sided dark-green needles clothe the twigs, and it bears the longest cones of any spruce - pendulous, cylindrical, 4 to 6 inches long, ripening from reddish to tan-brown. Long planted in North America for windbreaks, tall screens, Christmas trees, and timber, it is cold-hardy and adaptable in cool climates but is NOT heat-, drought-, or humidity-tolerant and falters toward the warm (zone 7) edge of its range.

Redvein enkianthus is a deciduous shrub endemic to Japan, valued for a two-season display: pendant clusters of creamy-white, red-veined bell flowers in spring followed by some of the most intense scarlet-to-copper autumn colour of any garden shrub. It holds an RHS Award of Garden Merit and is considered the hardiest of its genus, surviving to around -20°F (zone 4b). The honest catch is non-negotiable soil chemistry: it demands consistently moist, fertile, acid soil (pH 4.5-6.0) and will sulk or die in alkaline or clay ground - no amount of surface treatment permanently corrects a limey site, so confirm soil pH before planting. Note too that, as a member of the heath family, its tissues are best treated as toxic if ingested.

Rocky Mountain juniper (Juniperus scopulorum) is the western counterpart to eastern redcedar, and the two are confused constantly - with good reason, because where their ranges meet across the Great Plains they hybridise freely and intermediate trees are genuinely hard to name. Start with the caveat: Missouri Botanical Garden has no species-level page for it at all, only cultivar entries, and the species is the wrong plant for a hot humid climate. The Lady Bird Johnson Wildflower Center is blunt about it - drought and salt spray are fine, high humidity and high night temperatures are not - so this is a plant for the dry interior west and the plains, not the Southeast. What it offers there is unusual. It is a narrow, slow, drought-hard tree of dry rocky foothills, 30 to 50 feet on a good site and often far less, with shredding red-brown bark, blue-grey scale foliage, and high tolerance of caliche and limestone - the mirror image of the acid-soil hollies in this batch. It is dioecious like them, so the waxy blue-black cones appear only on female trees with a male nearby, and those cones are cones rather than fruit, taking about 18 months to ripen. It also lives an extraordinarily long time: the Jardine Juniper in Utah is over 1,500 years old and a New Mexico specimen counted 1,888 rings. The hard restriction is cedar-apple rust, for which it is an alternate host - do not plant it near an orchard.

Scots pine is the only pine native to northern Europe and one of the most widely distributed conifers in the world, ranging from Scotland and Spain across Eurasia to eastern Siberia and Mongolia. It is a long-lived, architectural tree prized for its distinctive orange-red upper bark, glaucous blue-green paired needles, and sculptural open crown that develops with age. In the garden it delivers year-round structure and strong wildlife value, but the honest catch is scale and mess: at full size it easily tops 60 to 80 feet, drips resin, sheds persistent acidic needle litter that suppresses ground-layer planting beneath it, and in parts of eastern North America and New Zealand it is listed as an invasive species that can spread into open habitats.

A vigorous, semi-evergreen climbing vine from subtropical southern South America, grown for its intricate, unmistakable flowers - white-to-pale-blue petals beneath a crown of blue-and-purple-banded filaments. POWO (Kew) and Flora e Funga do Brasil record it as native to southern Brazil, Argentina, Uruguay and Paraguay. It is by far the hardiest commonly-grown passionflower, root-hardy to roughly zone 6b/7 and resprouting after a freeze, and it climbs fast by tendrils to clothe a fence, arch or trellis. The egg-shaped orange fruit that follows is edible but bland and insipid - it is NOT the commercial passion fruit - and the leaves and unripe fruit contain cyanogenic compounds, so only the ripe pulp is safe to eat. Its vigour is a warning as much as a virtue: in mild climates it suckers and self-seeds and can become weedy or invasive, so give it room and curb it.

China fir is a large evergreen conifer native to south-central and southeastern China, grown for its bold, lance-shaped needles and strong pyramidal silhouette that makes it a striking focal point in large gardens. It performs well in zones 6b–9b in moist, well-drained soil with full sun to partial shade, reaching 30 to 75 feet in cultivation (much taller in native forest). The honest catch is its housekeeping habit: dead needles persist on interior and lower branches for years, coating the lower trunk in persistent brown ruffs that many gardeners find untidy - and because the species sprouts vigorously from the stump if cut or damaged, a careless prune can leave you with an unwanted multi-stemmed form.

Japanese apricot (Prunus mume) is a small to medium deciduous tree native to southern China and long cultivated across East Asia for its intensely fragrant late-winter blossoms and processed fruit (ume). In a Western garden it earns a focal-point role as one of the few trees that flowers in the heart of winter, ahead of forsythia and weeks before cherries. The honest catch is timing: flower buds open in January through February and are routinely killed by even a single night below 23°F, making the display unreliable in USDA zone 6 and northward without a sheltered south-facing wall; the raw seeds also contain amygdalin and must never be eaten unprocessed.

Persian silk tree is a fast-growing, deciduous small tree native to a broad arc from Iran and the Caucasus east through China and Korea, prized for its show-stopping pink powder-puff flowers in summer and delicate, fern-like bipinnate foliage. It thrives in hot, dry, sunny sites and establishes quickly, making it a striking focal-point specimen in zones 6b-9b. The honest catches are several: in the southeastern United States it is a documented invasive weed, seeding prolifically and escaping into roadsides and forest margins; it is short-lived in much of its US range due to mimosa vascular wilt (Fusarium); and its seeds, bark, and leaves contain toxic compounds, so fallen seedpods should be kept away from children and pets.
