Threadleaf bluestar is grown for two seasons at once: a haze of soft, powder-blue stars in late spring, and a billow of fine, needle-thin foliage that turns a blazing clear gold in fall. Native to the Ouachita Mountains of central Arkansas, Amsonia hubrichtii forms a large, dense, shrub-like clump of upright stems clothed in those threadlike leaves, and the autumn color alone earns a place in any sunny border.
Most bluestars are smooth, cool customers; Amsonia ludoviciana is the outlier of the group. The Louisiana bluestar belongs to the dogbane family, Apocynaceae, and shares the clan's five-petaled, star-shaped flowers and milky sap, but the leaves set the species apart: narrow and willowy, and unusually clothed beneath with a grey-white felt, a woolly tomentum that catches the light and lends the whole plant a soft, silvered cast rare in the genus. In spring, clustered flowers of a clean sky-blue open at the tips of the upright stems, quiet and steely and worked over by the first butterflies of the season.
Dwarf bluestar is the compact, well-behaved member of the clan, a tidy mound of upright stems and soft green leaves topped in late spring with clusters of powder-blue, star-shaped flowers. Often treated as a low form of the eastern bluestar, Amsonia montana stays small and shapely, a fine choice where the taller bluestars would sprawl.
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'.
Madeira vine is a fast, twining, deciduous climber with fleshy, heart-shaped leaves and sprays of tiny, fragrant cream-white flowers in late summer and fall. Anredera cordifolia climbs by winding tuberous stems, and a warty crop of aerial tubers along the stems, some as large as a small potato, is the surest mark of the plant and a ready means of increase.

Few vines work as hard for as little as the coral vine. Antigonon leptopus comes out of Mexico with heart-shaped leaves, tendrils that grab any small object within reach, and long sprays of small papery flowers in a hot, slightly unreasonable pink from midsummer until frost stops the show. The flowers are borne in such quantity that the whole plant seems to fizz, and the common names have piled up accordingly: coral vine, queen's wreath, Mexican creeper, chain of love, and, in the Gulf South, confederate vine. Bees find the plant before you do.
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.
A bold, handsome fern grown for foliage that holds through the year, Arachniodes simplicior 'Variegata' carries large, glossy, dark green fronds, each division marked down the center with a clean gold stripe. The variegated East Indian holly fern brings a strong, almost architectural texture to the shade garden, and the gold-striped fronds light up a dim corner.
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.
A small shrub built like a miniature tree, Ardisia crenata rises on one clean stem to two or four feet, occasionally six, and carries a single tier of glossy dark green leaves at the top like a parasol. The leaf margins are thick and scalloped, waved just enough to catch the light along the edge. Small white to pale pink stars hang in nodding clusters in late spring, lightly scented, and are followed by the reason anyone actually grows the shrub: tight bunches of round, lacquer-red berries that hold from autumn straight through to the next flowering.
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.
Low, shining, and quietly territorial, Ardisia japonica travels on slender underground stems and knits a dense evergreen carpet eight to twelve inches high across ground that most groundcovers refuse. The leaves are gathered in loose whorls near the tips of the stems, glossy and finely toothed, dark enough to read as almost black in deep shade. Small white to pale pink stars nod beneath the foliage in midsummer, easy to miss unless you kneel, and the berries that follow ripen coral red and hang on through winter, often still bright when the next year's flowers open.
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.
