North Atlantic moist mixed forests

The North Atlantic moist mixed forests stretch along the western and northern coasts of Ireland and Scotland, taking in southwest and west Ireland, western Scotland and the Outer Hebrides, the far north of Scotland, and the Northern Isles of Orkney and Shetland. Much of the landscape is now open blanket bog, dwarf-shrub heath, and rugged sea-cliff country, but the surviving semi-natural woodland is dominated by upland birch, native Scots pine (Pinus sylvestris), and Atlantic oak forest noted for its exceptional richness of mosses, lichens, liverworts, and ferns. The climate is warm-temperate with a strong oceanic influence, with annual temperatures generally ranging from 3 to 15 degrees Celsius and relatively high rainfall of roughly 1,000 to 1,500 mm. Despite extensive historical deforestation that left it classified as critical/endangered by the World Wildlife Fund, the ecoregion supports nearly a million breeding seabirds, including the world's largest gannet colony and Atlantic puffins, with the golden eagle as its flagship species. Gardeners in similar cool, wet, maritime climates may recognize natives of these heaths, such as ling heather (Calluna vulgaris) and bell heather (Erica cinerea).

Yucca filamentosa

Adam's needle

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.

Shrub

Full sun / Part shade

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 bold, clump-forming evergreen perennial from South Africa, grown for big rounded umbels of trumpet-shaped blue (or white) flowers held on tall bare stalks above arching, strap-shaped leaves in mid-to-late summer. It is widely sold as "lily of the Nile," but that is a misnomer - the plant is South African (the Cape provinces and KwaZulu-Natal), not from the Nile. Spectacular and easy in warm climates, this evergreen Agapanthus is frost-tender, so in cold-winter areas it is grown in a container and overwintered under cover. The RHS has given several Agapanthus praecox forms its Award of Garden Merit and rates this evergreen species half-hardy (H3 - needs winter protection).

Perennial

Full sun / Part shade

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.

Annual

Full sun / Part shade

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.

Pachysandra procumbens

Allegheny spurge

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.

Hippeastrum x hybridum

Amaryllis

Hippeastrum x hybridum is a complex garden hybrid derived from six or more wild Hippeastrum species native to tropical and subtropical South America, developed through intensive breeding since the late 18th century and now the dominant "amaryllis" sold worldwide as a holiday bulb. It produces spectacular trumpet-shaped flowers - 5 to 8 inches across - on stout leafless scapes in red, pink, white, orange, salmon, or bicolour, making it one of the most dramatic winter-flowering houseplants available. The honest catch is toxicity: the entire plant, especially the bulb, contains lycorine and related alkaloids at concentrations that cause vomiting, salivation, tremors, and hypotension in pets and children, so it must be placed out of reach and handled with care.

Perennial

Part sun / Part shade

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.

Shrub

Full sun / Part sun / Part shade

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.

Tree

Full sun / Part shade

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.

Shrub

Full sun / Part sun / Part shade

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.

Tree

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.

Perennial

Full sun / Part shade

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.

Shrub

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 to 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.

Tree

Full sun / Part sun / Part shade

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.

Tree

Full sun / Part shade

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.

Tree

Full sun / Part sun / Part shade

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.

Tree

American red raspberry

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.

Liquidambar styraciflua

American sweetgum

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.

Platanus occidentalis

American sycamore

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.

Amur maple (Acer ginnala, accepted by Kew's Plants of the World Online as Acer tataricum subsp. ginnala) is a small, fast-growing deciduous tree or large multi-stemmed shrub from northeastern Asia - the Russian Far East, northeastern China, and Korea. At 15 to 20 feet it fits where a full-size maple cannot, and it earns that place with three seasons of interest: fragrant greenish-yellow flowers in spring, which is an unusual scent for a maple and an early nectar source for bees; small glossy three-lobed leaves through summer; and reliable, often brilliant red-to-orange fall color that arrives early. It is also one of the hardiest maples, tolerant of cold, wind, dry soil, and a wide range of pH. The honest catch, and it is a serious one for North American gardeners, is that it self-sows prolifically and has escaped cultivation to become invasive across parts of the US Midwest and Northeast, where its shade-tolerant seedlings crowd native shrubs and understory trees in open woods, savannas, and prairies. Several states list it as invasive or a noxious weed. Check your local invasive-species list before planting, and be prepared to remove seedlings if you do.

Dierama pulcherrimum, angel's fishing rod, is an arching, more-or-less evergreen cormous perennial in the iris family (Iridaceae), endemic to the open summer-rainfall grasslands of the Eastern Cape of South Africa. It forms grassy tufts of long, narrow leaves from which tall, wiry, arching flower stems rise to about 4.9 feet (occasionally to 5.9 feet), each hung with pendulous, bell-shaped rosy-pink to purple flowers in summer - the namesake "fishing rod" silhouette over a pond or in a gravel garden. It is the load-bearing caution to note that this is only a borderline-hardy plant: RHS rates it H4 (hardy to roughly 14 to 23°F / USDA ~8b-9), so in colder zones it needs a sheltered, sunny, sharply drained spot, a winter mulch, or container/glasshouse protection, and it resents disturbance once established. It is not recorded as toxic - though it is grown purely as an ornamental and is not a food plant, so treat it as inedible. It is well-behaved (Least Concern in the wild, no recorded weediness) and suits borders, pond margins, and containers in mild-temperate gardens.

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.

Appenine deciduous montane forests

The Apennine deciduous montane forests occupy the higher elevations of the Apennine Mountains running down the spine of the Italian peninsula, surviving as disconnected patches that stretch southward for over 350 kilometers through central Italy. The dominant cover is montane broadleaf forest led by European beech (Fagus sylvatica), often mixed with silver fir (Abies alba), deciduous oaks (Quercus), maples (Acer), whitebeams and rowans (Sorbus), with cold meadows and grasslands taking over above the treeline. The climate is temperate-cool and notably wet, with rainfall ranging from roughly 1,000 mm in the southern mountains to 2,500 mm in the north and abundant winter snow at altitude. The ecoregion is the last stronghold of the critically endangered Marsican brown bear and the endemic Apennine (Abruzzo) chamois, and a 2017 assessment found about 46 percent of its area falls within protected reserves such as Abruzzo, Lazio and Molise National Park. For gardeners, several ornamental woody genera native here, including holly (Ilex aquifolium), yew (Taxus baccata) and linden (Tilia), are familiar temperate landscape plants.

Azores temperate mixed forests

The Azores temperate mixed forests cover the Azores archipelago, an autonomous region of Portugal whose nine principal volcanic islands lie roughly 1,350 to 1,500 km west of the Portuguese mainland. Lowland areas retain little natural vegetation, but above about 500 meters elevation enclaves of evergreen shrub forest persist, characterized by trees such as Laurus azorica, Juniperus brevifolia, Picconia azorica, and Erica azorica. The Gulf Stream gives the islands a mild maritime climate for their latitude, with summer averages near 21 degrees C and winter averages around 14.5 degrees C, and frost does not occur below 500 meters. The ecoregion is home to the endemic Azores bullfinch and the endemic Azores noctule bat; native laurel and juniper forests have been heavily displaced by introduced poplar, oak, and chestnut and by aggressive invasives. Gardeners may recognize native ornamentals from here, including the Azores blueberry (Vaccinium cylindraceum) and Azorean holly (Ilex perado subsp. azorica).

Balkan mixed forests

The Balkan mixed forests stretch across southeastern Europe, spanning Albania, Bosnia and Herzegovina, Bulgaria, Greece, Kosovo, Montenegro, North Macedonia, Romania, Serbia, and Turkey, reaching from the Black Sea toward the Adriatic. Deciduous oaks dominate most of the ecoregion's lower forests, most prominently Hungarian oak (Quercus frainetto) along with Turkey oak (Quercus cerris) and downy oak (Quercus pubescens), giving way above roughly 800 to 1,200 meters to European beech and conifers such as black pine, Scots pine, Bosnian pine, Macedonian pine, silver fir, and Norway spruce. The climate ranges from humid subtropical to humid warm-summer continental with wet winters, and a few high-rainfall pockets have been considered temperate rainforest relicts. The region is exceptionally rich and conservation-critical, hosting the greatest concentration of threatened mammal species in Europe, with the saker falcon as its flagship; the Shar Mountain area alone holds over 2,000 plant species, around 400 of them endemic to the Balkans.

Baltic mixed forests

The Baltic mixed forests stretch along the western and southern shores of the Baltic Sea, spanning northeastern Germany, northwestern Poland, eastern Denmark, and the southernmost tip of Sweden. Despite the name, the ecoregion does not reach the Baltic states; its woodlands are dominated by European beech (Fagus sylvatica), mixed with oak, ash, maple, linden, elm, hazel, rowan, and birch, alongside planted Norway spruce, forming beech, oak-beech, and pine-oak forest communities. The climate is mild and maritime, with mean annual temperatures roughly 7-13 degrees Celsius, gentle winters, and summers whose hottest months rarely exceed 20 degrees Celsius. The region supports around 340 bird species and serves as habitat for the aquatic warbler, described as the rarest passerine in mainland Europe, while mammals such as European otter, roe deer, red deer, wild boar, and wolf persist; the ecoregion is classified as Critical/Endangered. For gardeners, several native trees here, including silver birch, Norway maple, English oak, and European hornbeam, are familiar temperate ornamentals.

Cantabrian mixed forests

The Cantabrian mixed forests stretch across southwestern Europe, running along the coastal Cantabrian Mountains and Galician Massif of northern Spain, south into northern Portugal, and northward through the westernmost Pyrenees into southwestern France. Oak and beech woodlands predominate, with lowlands of English oak (Quercus robur), sweet chestnut (Castanea sativa), and European ash (Fraxinus excelsior) giving way to upland forests of sessile and Pyrenean oak (Quercus petraea and Quercus pyrenaica) and European beech (Fagus sylvatica), interspersed with montane heaths. The climate is mild and humid Atlantic, transitional between the Mediterranean and oceanic zones, with cold, snowy winters and more Mediterranean conditions in Galicia. This is the far-southwestern stronghold of the brown bear and shelters the critically endangered European mink, the rare Pyrenean desman, and the Cantabrian capercaillie, with Picos de Europa National Park alone hosting many orchid species. Gardeners may recognize natives such as sweet chestnut and the heathers of its montane heathlands.

Caspian Hyrcanian mixed forests

The Caspian Hyrcanian mixed forests form an 800-kilometer belt nestled between the Caspian Sea and the Elburz Mountains, lying mostly in northern Iran with portions reaching the Lenkoran lowlands and Talysh Mountains of southeastern Azerbaijan. These are temperate broadleaf and mixed deciduous forests, with Oriental beech the dominant species and characteristic trees including chestnut-leaved oak, European hornbeam, Persian ironwood, the Persian silk tree, and relict genera such as Caucasian zelkova and wingnut. The climate is humid and semi-subtropical at lower elevations, grading to oceanic and humid continental conditions in the mountains, and the high humidity drives exceptional forest productivity. The forests are an ancient Pleistocene refuge often called the "mother of European forests" because many plants dispersed across the continent from here after the glaciations; they were designated a UNESCO World Heritage Site in 2019 (expanded into Azerbaijan in 2023) and shelter wildlife such as the flagship Persian leopard, brown bear, and wolf. Several of their native trees, including the Persian silk tree and Persian ironwood, are familiar to gardeners as ornamentals.
