Azerbaijan shrub desert and steppe

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.

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

A circumboreal evergreen groundcover with small white-pink urn-shaped flowers, glossy leathery leaves, and bright-red bear-edible berries. One of the most reliable native evergreen groundcovers for cold sandy sites; widely used in northern landscapes for slope stabilization + low-maintenance native plantings.

A cool-season Asian leaf vegetable grown for its loose, non-heading rosette of dark-green leaves carried on broad, juicy white stalks - the spoon-shaped petioles that distinguish it from heading cabbages. Missouri Botanical Garden PlantFinder records that the group spans varieties from 3 to 4 inches to 24 inches tall and is edible at every stage, from seedlings to small immature heads to large mature heads and even while flowering. The stems are mild and juicy while the leaves carry a cabbage-like flavor; like other brassicas it tolerates light frosts but bolts in summer heat.

A cool-season vegetable grown for its large, tight, terminal head of green flower buds on a thick edible stem, framed by waxy blue-green leaves. Grown as an annual; it grows poorly once daytime temperatures consistently exceed 80°F, so it is timed for spring and fall. Harvest promptly while the head is firm and tight, before the buds begin to open.

A slow-growing, long-season cool-weather vegetable grown for the miniature cabbage-like buds (1 to 2 inches wide) that form in the leaf axils along a single 2-3 foot stem. It is the same species as kale, cabbage, broccoli, cauliflower, and kohlrabi, differing only by cultivar group. Flavor improves after the first fall frost, so it is timed for a cool-temperature autumn harvest rather than summer heat.

A cool-weather leaf vegetable grown for its dense, edible head of tightly wrapped blue-green, red, or wrinkled (Savoy) leaves. A biennial almost always grown as an annual, it forms a 3-4 pound head in about 80 days and rarely flowers in cultivation. It shares its species with kale, Brussels sprouts, broccoli, cauliflower, and kohlrabi, and grows poorly once daytime temperatures stay above 80°F.

A cool-weather brassica grown for the large, tight head of aborted white flower buds - the "curd" - that forms at the center of a rosette of broad blue-green leaves. The same species as cabbage, broccoli, kale, Brussels sprouts, and kohlrabi, it is harvested before the curd ever opens into true flowers. Grown as an annual; notoriously fussy, with little tolerance for heat, drought, or cold, it does best in the cool temperatures of spring and fall.

A cool-season biennial vegetable in the carrot family (Apiaceae), grown as an annual for its crisp, edible ribbed leaf stalks. Apium graveolens is native to temperate Mediterranean Europe, Asia, and Africa - not North America. It demands rich, consistently moist soil and steady cool temperatures (60 to 75°F); heat and drought turn the stalks stringy and bitter, which is why it is one of the more finicky garden vegetables.

A warm-weather annual of the carrot family grown in herb gardens for two distinct crops from one plant: the lacy, strong-scented foliage harvested young as cilantro, and the aromatic dried seed harvested as coriander. The plant bolts and flowers quickly in hot weather, throwing up showy white-to-pale-lavender umbels and a marked leaf dimorphism - broad scalloped lower leaves give way to fine, thread-like upper foliage on the flowering stems. Fast and easy from a direct sowing, it is best succession-planted for a steady leaf harvest before heat triggers bolting.

Common juniper (Juniperus communis) has the largest natural range of any woody plant on earth. Missouri Botanical Garden calls it "the most widespread conifer growing in the world today", and the WGSRPD range mapped in this record runs to 130 botanical countries: a circumboreal band right around North America, Europe and Asia that reaches inside the Arctic Circle, plus one stranded population in the Atlas Mountains of North Africa. Its second claim is in the drinks cabinet. The waxy blue-black "berries" are fleshy seed cones rather than fruit, and they are the botanical that makes gin gin - the spirit category is legally defined by juniper being the predominant flavour, in EU spirit-drink law and in the US standards of identity alike. The honest caveat is that none of that makes it a good bet in most American gardens. MBG records "superior tolerance for cold temperatures and superior intolerance for heat and humidity" and states plainly that it is not recommended for planting south of USDA Zone 6, and it also notes that species plants are rarely sold in commerce - what a garden centre stocks is cultivars. Settle the habit question before buying, too, because the same species is a 9-to-12-inch prostrate mat on an exposed ridge, a 5-to-15-foot multi-stemmed shrub through most of the US, and occasionally a 45-foot tree.

An upright, multi-stemmed, suckering deciduous shrub in the olive family, grown for its intensely fragrant mid-to-late-spring (May) bloom of lilac-purple flowers in large conical panicles. Native to southeastern Europe and cultivated in North America since the early 1600s, it matures to 12 to 16 feet tall with blue-green, pointed-ovate to heart-shaped leaves. It needs cold winters and cool summers - and offers few ornamental features after bloom, with leggy form, no fall color, and summer powdery mildew.

The cultivated cereal oat, an erect cool-season annual grass grown for grain, forage, and - increasingly in gardens - as a fast, soil-building cover crop. From a spring or late-summer sowing it shoots up to 2 to 4 feet of slender, upright culms topped by an open, airy seed head (a spreading panicle) whose dangling spikelets ripen from green to gold. Domesticated in the Old World from wild oats, it is not a native wildflower but a true annual crop: it germinates fast, smothers weeds, builds biomass, and in cold zones conveniently winter-kills to leave an easy mulch in spring. Gardeners reach for it most as a green manure and erosion-stopping nurse crop, and for the soft, grassy texture and ripening-gold seed heads it adds while it grows.
