Mid-Atlantic US coastal savannas

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.

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.

Subalpine fir (Abies lasiocarpa) is the narrowest conifer in western North America and, for most gardens, the wrong tree. It is a timberline species: the US Forest Service silvical account puts its climate at a mean July temperature of 45 to 60°F, with more than 24 inches of precipitation of which much falls as snow, on ground that is frozen or under snow for a large part of the year. Bring it down the mountain into a hot summer, a humid one, or a polluted one and it sulks, thins and dies, and it does so slowly enough that people keep watering it. The Lady Bird Johnson Wildflower Center calls it a spire-like evergreen of 30 to 50 feet with stiff horizontal limbs branched to the ground, and that spire is the whole ornamental argument - a crown so narrow it can be a fifth as wide as it is tall, which is a snow-shedding adaptation rather than a nursery selection. At and above treeline it stops being a tree at all and grows as krummholz, low sprawling mats scoured by wind, and reproduces by LAYERING: a branch pressed into the ground roots and becomes a new stem, so a single tree can leave behind a ring of clones that mountaineers call an atoll. Two honest problems follow it down into cultivation. It is slow and, for a conifer, short-lived and structurally weak - thin bark, persistent dead branches, easily windthrown - and its pest list is serious: balsam woolly adelgid (Adelges piceae), introduced from Europe and the most destructive insect on this species in the Cascades, and the western balsam bark beetle (Dryocoetes confusus), which together with Armillaria root rot drives the mortality complex that has killed subalpine fir across large areas of the Rockies. Like every true fir it carries its cones UPRIGHT on the upper branches, dark purple ripening brown, and those cones never fall whole - they shatter on the tree and leave a bare central spike standing on the branch, which is the single quickest way to tell an Abies from a Picea at a glance.

A tall, summer-growing cormous perennial from across sub-Saharan Africa, grown for arching spikes of large, hooded, orange-to-red-and-yellow flowers in summer over fans of sword-shaped leaves. This is the widespread wild African gladiolus and a key ancestor of the big garden gladioli. Unlike the winter-growing Cape bulbs, it is a SUMMER-GROWING corm: plant in spring, grow and flower through summer, then it dies back to a dormant corm for winter. It wants full sun, well-drained soil, and summer moisture, and is one of the hardier species gladioli - surviving to about USDA zone 7 with a deep winter mulch or by lifting the corms in cold-winter areas. The corms are toxic and irritant if eaten and have been used in traditional medicine, never as food. In the wild the hooded flowers are pollinated by sunbirds and long-tongued insects.

A deciduous Eastern-Asian fruit tree with a rounded, spreading crown that the Missouri Botanical Garden lists at 20 to 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 to 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 bushy, semi-evergreen small shrub (subshrub) grown for an exceptionally long succession of two-lipped flowers - classically bright red or magenta-pink, with many named cultivars such as the bicolour 'Hot Lips' - borne from early summer right up to the first frosts. Its small aromatic leaves are often said to smell of blackcurrant when crushed. One of the very best garden plants for pollinators in a hot, dry, sunny spot, it is tough and free-flowering but only borderline hardy (RHS H4): in cold-winter climates it needs a warm, sheltered position and sharp drainage and is often grown as a tender perennial. It is an ORNAMENTAL salvia and is NOT the culinary sage (that is Salvia officinalis) - it is grown for flowers and pollinators, not for food.

Bear's breeches is a bold Mediterranean perennial whose dramatically lobed, glossy leaves inspired the Corinthian column capital of classical architecture. Its wild native range spans the central and eastern Mediterranean - Italy, Sicily, Sardinia, the Balkans, Greece, the Aegean, Anatolia and the Levant, plus NW Africa (Morocco, Algeria, Tunisia); it is naturalised (not native) further west into Iberia. In gardens it serves as an architectural statement plant, producing tall white-and-purple flower spikes in summer on established clumps. The honest catch is its root system: fleshy, deep-running tuberous roots regenerate readily from the smallest fragment, making Acanthus mollis genuinely difficult to eradicate once established and a declared invasive in Australia and New Zealand, so site selection is a permanent decision.

A handsome, intensely aromatic broadleaf evergreen tree native to coastal California and southwestern Oregon, where it grows from a dense, rounded shade tree of 30 to 75 feet down to a multi-stemmed large shrub on harsher sites. The narrow, glossy, dark-green leaves are richly scented - crush one and the pungent, spicy oil is unmistakable - and small clusters of pale yellow-green flowers in late winter and early spring give way to round, olive-like fruit that ripens from green to purple. It is one of the most fragrant trees of the West Coast and a tough, drought-adapted evergreen for zones 7-9, but it carries two important cautions: the oils are strong enough to earn it the nickname 'headache tree,' and it is a major foliar host and reservoir for Phytophthora ramorum, the pathogen behind Sudden Oak Death, so it should not be planted near oaks or tanoaks in affected regions.

A broadleaf evergreen shrub from Japan, China, and Korea, grown for showy 3-5 inch winter-to-spring flowers in white, pink, red, yellow, and lavender against glossy, leathery, dark green leaves. The most widely cultivated camellia, with thousands of named varieties and a single straight-species form whose broad overlapping petals surround a dense boss of golden-yellow stamens. Winter hardy only to USDA zones 7-9, it needs moist, acidic, organically rich soil and the shelter of part shade.

Loropetalum chinense is an evergreen shrub native to woodlands and thickets across southern China, Japan, Taiwan, and adjacent parts of Southeast Asia, valued in gardens for its distinctive ribbon-like flowers and, in the popular purple-leaved forms, year-round burgundy foliage. It thrives in zones 7-9 as a bold structural shrub or hedging plant, blooming most heavily in late winter to early spring. The honest catch is its absolute dependence on acidic soil: even slightly alkaline pH triggers iron chlorosis, and in the Southeastern US a bacterial crown gall disease can cause rapid branch dieback and plant death, making site preparation and soil testing non-negotiable before planting.

Chinese holly (Ilex cornuta) is the only plant in this holly group that is not from here, and that is the first thing to say about it. It is native to eastern China and Korea, it is sold across the American South by the pallet, and Missouri Botanical Garden records plainly that "it has naturalized from garden plantings in North Carolina and Alabama". Kew's data adds introduced occurrences in Alabama, Arkansas, California, Florida, Louisiana, both Carolinas and Tennessee, and the mechanism is the plant's own selling point: birds eat the showy red drupes and carry the seed into woodland edges. On its merits it is a genuinely tough broadleaf evergreen - 8 to 15 feet each way, heat and drought tolerant, deer-proof, comfortable in city conditions, and carrying the most distinctive leaf in the genus, a stiff rectangular blade to four inches with three big spines at the blunt end rather than the wavy spined outline of English holly. The catch beyond the escape risk is cold: it is zone 7 to 9, and Missouri Botanical Garden says flatly that "winter hardiness is a significant problem in St. Louis". Set against inkberry, yaupon and possumhaw in this batch, it is the one whose wildlife value stops at the fruit.

Cider gum is a fast-growing evergreen tree from the woodlands of Tasmania's central plateau and one of the most cold-hardy eucalypts: Trees and Shrubs Online calls it the hardiest of the tree-form eucalypts planted widely enough to judge, and the RHS rates it H5, hardy in most of the UK even in severe winters. Plants For A Future gives it long spells down to 7°F and short ones down to -0°F. Left unpruned it grows into a tree of 40 to 100 feet with peeling cream and brown bark and grey-green, sickle-shaped adult leaves, but many gardeners cut it back hard every spring to keep it in the rounded, glaucous-blue juvenile foliage it is best known for. Small white flowers in clusters of three appear on trees allowed to mature, usually in summer or autumn in British gardens. The name refers to its sweet sap, which the Aboriginal people of Tasmania fermented into a drink called way-a-linah. The leaves hold eucalyptus oil, which is poisonous if swallowed (Plants For A Future reports deaths after ingestion of 4-24 ml of eucalyptus oils), so keep foliage, prunings and any oil away from children and pets. Outside its range it has naturalized in woodland and on roadsides in south-eastern England, where it occasionally regenerates from seed, while in the wild it is assessed as Endangered on the IUCN Red List.

A tuberous-rooted member of the aster family native to Mexico and Central America, grown for showy summer-to-fall blooms in nearly every color except blue. Hybrids in commerce span ten flower-form groups (single, anemone, collarette, waterlily, decorative, fall, pompon, cactus, semi-cactus, and miscellaneous) and range from 1 to 6 feet tall. Winter-hardy only to USDA Zones 7-10; in colder regions the tubers are lifted in fall and stored frost-free, so most North American gardeners grow it as a summer annual.

David viburnum is a compact, mound-forming evergreen shrub native to western China (its provenance usually given as the Sichuan / Yunnan region), grown for its bold, deeply three-veined glossy leaves, small clusters of white flowers in late spring, and - when fruiting - striking oval drupes in a distinctive metallic turquoise-blue. It holds the RHS Award of Garden Merit and suits the front of borders, shaded corners, and containers in cool-temperate to mild climates. The honest catch is a fundamental one: it is dioecious, so you must plant at least one male and one female together to get the celebrated blue fruit - a single plant in isolation will never berry, and many gardeners discover this only after years of waiting.

A graceful, large evergreen conifer from the western Himalayas, prized as a specimen for its broadly pyramidal form, gently nodding leader, and sweeping branches whose tips droop in soft, weeping curtains. Slender blue-green to gray-green needles are borne in dense whorled clusters on short spurs, and barrel-shaped upright cones sit on the upper branches, ripening from blue-green to reddish-brown and disintegrating on the tree. In the landscape it typically reaches 30 to 50 feet (with much greater potential in age and ideal sites), needs real room to spread, and is the most heat- and warmth-tolerant of the true cedars - thriving in zones 7-9 where spruce and fir falter, but it does want good drainage and is not a small-garden tree.
