Sechura desert

The Sechura Desert stretches along the western coast of Peru, running south of the Piura Region across the Piura and Lambayeque areas and reaching 20 to 100 km inland from the Pacific to the foothills of the Andes; it sits in the Neotropic realm and forms one of two arid ecoregions in One Earth's South American Coastal Deserts bioregion alongside the Atacama. Plant cover is generally sparse, but northern areas hold carob trees and mesquite, while willows, Tessaria species, evergreens, and beach grasses persist where water allows, and cacti occupy the arid rocky scrublands. The climate is one of the most arid on Earth, driven by the upwelling of cold coastal waters and subtropical atmospheric subsidence, with coastal fog supplying moisture and occasional El Niño years bringing heavy flooding. Despite low overall diversity the desert shelters distinctive wildlife, including the Sechuran fox, the endemic Peru Pacific iguana and coastal desert iguana, and endangered birds such as the white-winged guan and russet-bellied spinetail, though only a small fraction of the region is currently protected. For gardeners in hot, dry climates, the desert's native carob and mesquite (Prosopis) trees point to drought-hardy genera adapted to these conditions.

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 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.

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.

Tree

Full sun / 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.

Tree

Full sun / Part sun / Part shade

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

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

Full sun / Part shade

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

Full sun / Part sun / Part shade

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.

Tree

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.

Hydrangea arborescens

Annabelle hydrangea

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.

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.

Araya and Paria xeric scrub

The Araya and Paria xeric scrub stretches along Venezuela's northeastern Caribbean coast, covering the Araya and Paria peninsulas, the area around Cumaná, and the offshore islands of Margarita, Coche, and Cubagua. Its vegetation is a mosaic of salt-tolerant dune herbs, dry thorn scrub studded with columnar and prickly-pear cacti such as Stenocereus and Opuntia, and low deciduous woodland with trees including Bursera, Prosopis, and Parkinsonia, grading into semi-deciduous and evergreen forest on the higher hills. The climate is hot and markedly arid, with average temperatures around 24 to 27 degrees Celsius and rainfall that is very sparse on the Araya Peninsula but much higher on the wetter Paria slopes. The ecoregion harbors notable wildlife, most famously the threatened yellow-shouldered amazon parrot, alongside breeding sea turtles and a number of endemic plants, yet it is considered critically threatened by overgrazing, deforestation, sand extraction, and coastal urbanization. For gardeners in hot, dry climates, several drought-hardy genera native here, including the cacti Stenocereus and Opuntia and the flowering tree Parkinsonia, are widely grown as ornamentals.

Atacama desert

The Atacama Desert ecoregion runs as a continuous strip for nearly 1,000 kilometers along the narrow coast of the northern third of Chile, extending toward southern Peru, within the Neotropic realm. Its interior is one of the driest places on Earth and almost without vegetation, while life concentrates on coastal slopes and ravines where Pacific fog and winter drizzle sustain isolated oases known as lomas. Characteristic plants include columnar and cushion cacti such as Eulychnia, Copiapoa, Browningia, and Leucostele, alongside bromeliads on sandy ground and the endemic tamarugo tree, with around 550 species of ferns, gymnosperms, and flowering plants recorded. Endemism here can exceed 60 percent, and the desert is the largest fog desert on the planet, supporting a sparse but highly adapted fauna whose flagship is Darwin's leaf-eared mouse. For gardeners, several of its hardy succulents, notably Copiapoa cacti, are prized ornamentals well suited to arid, low-water plantings.

Caribbean shrublands

The Caribbean Shrublands ecoregion is a Neotropic strip of xeric scrub scattered across the low, dry islands of the Caribbean, including the Cayman Islands, all of Barbados, the coastal Windward Islands (parts of Grenada, St. Lucia, Martinique, Dominica, and Trinidad), and much of the Leeward Islands, from Guadeloupe's Grande-Terre and Marie-Galante to Antigua, Anguilla, St. Martin, St. Barthélemy, and the eastern Virgin Islands. Its vegetation is seral in character, grading from herbaceous coastal strand through scrublands and savannas to littoral woodland, and it sits within a broader island setting of tropical dry forests and mangroves. The climate is warm and tropical, with the Cayman Islands experiencing a humid regime, a distinct wet season from May to November, and persistent trade winds. The ecoregion holds notable island endemism: the Cayman Islands alone support 26 herpetofauna species, about three-quarters of them endemic, while the critically endangered Grenada dove, Grenada's national bird, persists in mature dry scrub lowlands and hillsides. Habitat loss and introduced species are the leading threats to these naturally limited coastal scrub habitats.

Cuban cactus scrub

The Cuban cactus scrub is a xeric shrubland ecoregion strung along the leeward, southeastern coast of Cuba, concentrated in the provinces of Guantanamo and Santiago de Cuba and covering roughly 3,300 square kilometers. Its vegetation is dominated by columnar cacti and other succulents alongside palms, organized into coastal scrubland zones rooted in shallow rendzina soils derived from coralline limestone; characteristic woody genera include Bursera, Croton, Acacia, and Cordia. The climate is semidesert, receiving less than 800 mm of rainfall a year with a prolonged dry period and average temperatures near 26 degrees Celsius. The ecoregion is an important center of plant diversity and endemism, sheltering endemic reptiles such as the Cuban rock iguana along with the flagship Cuban flower bat, a key pollinator of its native flora. For gardeners working hot, dry coastal sites, the region is home to drought-hardy ornamental cactus genera native here, including Opuntia, Harrisia, Pilosocereus, Melocactus, and Leptocereus.

Galápagos Islands xeric scrub

The Galápagos Islands xeric scrub covers Ecuador's Galápagos archipelago, roughly 128 volcanic islands scattered across the Pacific some 960 km west of the South American mainland. Across the lowland arid zone the vegetation is drought-tolerant scrub and dry forest, characterized by palo santo (Bursera graveolens), the endemic guayabillo (Psidium galapageium), coastal saltbush (Cryptocarpus pyriformis) and Maytenus, and several endemic cactus genera including the tree-like prickly pears (Opuntia), Jasminocereus, and Brachycereus. The climate is semi-arid and oceanic with two seasons: a warm wet season from about December to May and a cooler, drier garúa season, while rainfall climbs sharply with elevation so that higher slopes carry moister Scalesia woodlands. The islands hold around 500 native vascular plant species, roughly 180 of them endemic, and the ecoregion is the celebrated home of the giant Galápagos tortoise and an emblem of evolutionary endemism. Its native flora is now critically threatened by introduced and invasive species, including goats and numerous non-native plants, though nearly the entire ecoregion lies within Galápagos National Park.

Guajira-Barranquilla xeric scrub

The Guajira-Barranquilla xeric scrub is an arid shrubland ecoregion strung along the Caribbean coast of Colombia and Venezuela, occupying the Guajira Peninsula and the Ranchería river valley and reaching out to the ABC Islands of the Leeward Antilles. Its dry lowlands are dominated by thorny trees and succulents, with characteristic genera including Acacia, Prosopis (mesquite), and a wealth of cacti such as Opuntia. The climate is hot and dry, with low and highly variable annual rainfall and warm temperatures year-round, a pocket of true xerophytic vegetation within the otherwise wet Neotropics. The region is notable as habitat for a large community of Caribbean flamingo (Phoenicopterus ruber) alongside a diversity of birds and bats, and much of the Serranía de Macuira is protected within Macuira National Park. For gardeners drawn to drought-tolerant plantings, the Los Flamencos Sanctuary here is recognized as a center of plant diversity for Salvia, the bromeliad Hechtia, and native cacti.
