Apple serviceberry, Amelanchier x grandiflora, is the graceful natural hybrid of two eastern native serviceberries, the downy and the smooth Allegheny, and 'Princess Diana' is among the loveliest selections of the group. The plant appeared in a cultivated garden in Elm Grove, Wisconsin in the mid-1980s and was granted U.S. Plant Patent 6,041 in 1987, chosen for a wide, gracefully spreading canopy, generous white bloom, and fall color that arrives early and holds late. Where many serviceberries grow stiffly upright, 'Princess Diana' reaches outward, a small tree with the airy, layered poise the name suggests.
Smooth false indigo is a rare deciduous shrub of sandy southern streambanks, carrying pinnate, compound leaves whose leaflets are notably large and rounded, a softer, more luxuriant texture than the ferny foliage of the common false indigos. In early summer the branch tips raise slender spikes of tiny blue to purple flowers, each lit with the bright orange anthers typical of the genus.
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'.
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.
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.
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.
Baccharis halimifolia is a plant of edges and thresholds, growing where the land loosens and blurs into water: salt marsh margins, ditches, tidal creeks, and back dunes. In fall, when most things are shutting down, the groundsel bush erupts into a soft storm of white seed fluff, like a marsh firework frozen mid-explosion. This is the shrub that coastal Louisiana calls manglier, that botanists call groundsel bush or eastern baccharis, and that local healers have quietly trusted for generations.

Baptisia alba, white wild indigo, is a striking native perennial of tall spires of white, pea-like flowers over deep blue-green foliage. Native to the eastern and central United States, the species carries a rich history as a dye plant, used by Native American peoples and early settlers as a substitute for true indigo, and the genus name, from the Greek bapto, to dip, records that role.
When Woodlanders began in 1980, this was about the only Baptisia known to gardeners; we went on to introduce many of the species that have since become popular garden perennials. Baptisia australis, blue wild indigo, is a long-lived native, essentially a prairie plant of open glades on limestone soil, with handsome olive-green compound leaves topped in spring by spikes of bright indigo-blue, pea-like flowers.
Baptisia megacarpa, the Apalachicola or bigpod wild indigo, is a rare and remarkable native of the floodplains and forested slopes of the Florida Panhandle, southeastern Alabama, and southwestern Georgia. The species grows on sandy ridges and stream terraces in the Chattahoochee River drainage, finely tuned to that particular corner of the South.
