Eastern bluestar is the bluestar most gardeners know, a robust native perennial with broader, willowy oval leaves and the clear blue, star-shaped flowers that name the genus, carried in clusters at the stem tips in spring. Amsonia tabernaemontana grows happily in deep, moist soil in part shade, and rewards almost any reasonable site with bloom and easy good health.
Flame acanthus, better known as hummingbird bush, is a tough, airy deciduous shrub for hot, dry places, hung from late spring until frost with slender orange to red tubular flowers that ruby-throated hummingbirds cannot resist. Small, pointed leaves give a light, open texture, and the long bloom season makes Anisacanthus wrightii one of the best hummingbird plants for the southern garden.
A pumpkin-orange selection of the classic flame acanthus, Anisacanthus wrightii 'Pumpkin' trades the usual scarlet for warm, glowing orange, lighting the late-season garden with the same slender, tubular, hummingbird flowers. The clone was discovered at the San Antonio Botanic Garden and is generally taken to be the selection known as 'Pumpkin'.
Few spring sights stir the woodland gardener like wild columbine in bloom. Aquilegia canadensis hangs nodding red-and-yellow bells, spurred and lantern-like, over lacy blue-green foliage, catching the low light of April along forest edges, rocky outcrops, and Appalachian coves where the plant has grown for ages. The eastern red columbine, or simply wild columbine, is among the most beloved of native spring wildflowers.
Araucaria angustifolia is a living relic, one of the last of an ancient conifer family that shaded the dinosaurs across the supercontinent of Gondwana. The Paraná pine belongs to the Araucariaceae, kin to the Chilean monkey puzzle, the Norfolk Island pine, the Australian bunya, and the famously rediscovered Wollemi pine, a lineage once spread worldwide and now scattered mostly across the Southern Hemisphere. Despite the common name, the tree is no true pine at all, but something far older and stranger, holding stiff, sharp, dark green leaves on the branch for a decade or more.
The strawberry tree is a handsome broadleaf evergreen, a large shrub or small tree hung in fall and early winter with clusters of nodding, urn-shaped, pinkish-white flowers, just as the previous year's fruit ripens to warty, orange-red, strawberry-like globes. Flowers and fruit on the branches at once is the particular charm of Arbutus unedo, and the glossy leaves and shredding cinnamon bark hold interest year round.

A hybrid strawberry tree, Arbutus x andrachnoides crosses the strawberry tree, Arbutus unedo, with the Grecian strawberry tree, A. andrachne, and takes the best of both: white, bell-shaped flowers and pink, strawberry-like fruit on a small evergreen tree, over dark green leaves an inch and a half to four inches long. The real prize comes with age, when the bark peels away to a smooth, rich red-brown that rivals any madrone.
The uncommon white-berried form of coral ardisia, Ardisia crenata 'Alba' is a small, neat evergreen shrub of glossy, scallop-edged dark green leaves, hung in fall and winter with clusters of round white berries in place of the usual coral red. The pale fruit and shining foliage give a long season of quiet interest, indoors in a bright room or out in a shaded, frost-free garden.
Ardisia japonica 'Hakuokan' is a jewel of the Japanese shade garden, a low evergreen groundcover whose small, glossy, leathery leaves are edged in a clean band of creamy white. The green species, called yabukoji in Japan and marlberry in English, has grown wild in the woodland understory of Japan, Korea, China, and Taiwan for ages, spreading quietly by underground runners into knee-low colonies. 'Hakuokan', a name that reads roughly as white royal crown, is a variegated selection prized by collectors, slower and more compact than the plain species and all the more luminous for the pale margin that catches light in a dim corner.
Ardisia japonica 'Hinode' is a variegated form of the Japanese marlberry, each glossy, dark green leaf marked with a broad gold band down the center. Low and slowly spreading, this evergreen carpets shaded ground at eight to twelve inches, lit by the gold variegation and dotted in fall with bright red berries that hold into winter.
Aronia arbutifolia has grown in the wet woods and pocosins of the eastern United States for a very long time, largely unbothered by the horticultural world's attention. 'Brilliantissima' changed that. Selected for foliage with a deeper gloss and berries of a more saturated, almost lacquered red than the straight species, this is the form that finally made gardeners look twice at a native shrub long overlooked despite centuries of quiet usefulness.
Swamp milkweed brings beauty and biodiversity to the moist garden. Asclepias incarnata is a native perennial prized for domed clusters of rosy pink, vanilla-scented flowers and for a vital role in feeding pollinators, native to wet meadows, streambanks, and lowland prairies across much of North America. The plant takes happily to rain gardens, wet soils, and sunny borders alike, a natural for the ecologically minded gardener.
The white-flowered form of swamp milkweed, Asclepias incarnata 'Ice Ballet' carries the same upright, well-mannered habit as the species but trades rosy pink for clusters of pure, cool white, held atop sturdy three-to-four-foot stems through summer. The effect is fresh and luminous in a moist border, and just as useful to wildlife.
Butterfly weed is the orange star of the summer meadow, a strong-growing native perennial of eastern North America and a longtime favorite of gardeners. Flower color ranges from clear yellow to nearly red, but the typical Asclepias tuberosa blazes a vivid orange that butterflies, and the eye, find from across the garden.

Asimina obovata is the bigflower pawpaw, a Florida native that carries the largest, showiest blooms in a genus better known for its fruit. The pawpaws are the temperate outliers of the Annonaceae, the custard apple family whose tropical members include the cherimoya, soursop, and ylang-ylang, and Asimina alone among them ventures north into the sandy uplands of the American Southeast. The genus name descends from an early Native American word for the fruit, carried into English through the French asiminier, while obovata describes the egg-shaped leaves, broadest above the middle.
The cast iron plant earned the name honestly. Aspidistra elatior is the toughest of evergreen foliage plants, sending up broad, glossy, dark green blades straight from the soil and holding strong form year round in conditions that defeat almost everything else. A Victorian parlor favorite for surviving gaslight and neglect, the cast iron plant is just as valuable in the deep shade of the garden.
A boldly striped form of the cast iron plant, Aspidistra elatior 'Variegata' carries the same broad, leathery, evergreen blades, each brushed lengthwise with bands of creamy white over deep glossy green. The variegation lights up a shaded corner, and the toughness is all there too: this is a near-indestructible evergreen for difficult, low-light places.
Smooth aster is one of the cleanest and most dependable of the fall natives, and 'Bluebird' is among the best forms. Aster laevis 'Bluebird' builds an upright, vase-shaped clump of smooth, blue-green foliage, then opens, in late summer and fall, sprays of violet-blue daisies centered in gold, a generous late feast for bees and butterflies as the season winds down.
Aromatic aster is the toughest and most fragrant of the fall asters, and 'Raydon's Favorite' is the classic selection. Aster oblongifolius 'Raydon's Favorite' forms a dense, rounded mound of small leaves that release a clean, balsam-like scent when brushed, and in early to mid fall vanishes under a haze of lavender-blue, gold-centered daisies.
Aucuba chinensis is the lesser-known Chinese cousin of the familiar gold dust plant, a rare, broad, evergreen shrub for deep shade. The thick, leathery, dark green leaves are coarsely toothed and dusted with scattered yellow flecks, holding their color year round and bringing a glossy, tropical-looking presence to a shaded bed.
