Blue-stemmed goldenrod is the goldenrod for shade. Where most of the clan demand open sun, Solidago caesia threads through the dappled light of the eastern woodland, arching slender, blue-purple stems that carry small, brilliant yellow flowers packed into the leaf axils, so the bloom runs the whole length of each stem like a garland. That habit gives the second common name, wreath goldenrod, and the late-summer to autumn color arrives just as the shade garden begins to fade.
Styrax obassia, the fragrant snowbell, is the bold-leaved cousin of the more familiar Japanese snowbell, a small deciduous tree from the mountain woodlands of Japan, Korea, and China. Where Styrax japonicus hides small bells beneath fine, layered branches, the fragrant snowbell wears large, rounded, almost tropical leaves up to eight inches across, and hangs long, drooping chains of white, bell-shaped flowers that carry a sweet perfume through the late-spring garden.
In the open oak-hickory woodlands and fire-maintained savannas that once covered the upland South, Georgia aster was a fixture, a late-season native sending up violet-blue flowers in October and November at the precise moment when almost everything else had finished. That landscape is largely gone now, and the aster went with most of it.
Copper Canyon daisy is a big, aromatic, autumn-flowering marigold from the mountains of southern Arizona and adjacent northern Mexico, grown as much for the scent as the show. Brush against the finely divided, fern-like foliage and the plant releases a strong, distinctive fragrance, a mix of citrus, anise, and marigold that some find intoxicating and others frankly pungent. Tagetes lemmonii builds a soft, shrubby mound three to four feet high and wider still.
Cape honeysuckle is a rangy, vine-like evergreen shrub from southern Africa, grown for glossy, compound leaves like a trumpet vine's and, above all, for the showy clusters of orange to orange-red tubular flowers that hummingbirds and, in the wild, sunbirds cannot resist. A member of the trumpet-vine family, Bignoniaceae, the plant can be trained up a support, clipped into a loose informal hedge, or left to cascade over a wall or bank.
Few shrubs wear a name as plainly as this one. Odoratissimum is Latin for the most fragrant, the sweetest-scented, and sweet viburnum earns the superlative in late spring, when conical panicles of tiny white flowers open across the canopy and carry a soft, honeyed perfume on warm air. A member of the moschatel family, Adoxaceae, and a cousin of the elders and the arrowwoods, Viburnum odoratissimum ranges as a wild plant from the Himalayan foothills of India through Myanmar, Thailand, and Vietnam to China, Taiwan, Korea, and Japan, a broad Asian sweep that hints at the plant's easy adaptability in the warm garden.
A tough, glossy evergreen born of two Chinese parents and a Prague nursery. Viburnum x pragense is the cross of the leatherleaf viburnum, Viburnum rhytidophyllum, with the service viburnum, Viburnum utile, first raised by the plantsman Josef Vik at the Municipal Nurseries of Prague in 1955 and named for the city in 1959. The epithet pragense simply means of Prague, a rare instance of a garden hybrid carrying a birthplace rather than a botanist.
There are few sights more stirring than a wisteria in bloom, and 'Amethyst Falls' offers all the romance without the unruly habits of the Asian cousins. This refined selection of the native American wisteria, Wisteria frutescens, pours out cascades of fragrant, lavender-violet blossoms in late spring, with smaller flushes through summer, a soft echo of springtime returning again and again.
John Bartram collected Xanthorhiza simplicissima from the Carolina mountains sometime before 1776 and brought the plant back to his famous Philadelphia garden, which tells you two things: that yellowroot has been in cultivation for as long as this country has existed, and that people who know plants have always recognized something worth paying attention to here. The Cherokee had known the plant far longer, using the roots, sliced open to reveal a vivid, almost electric chrome yellow, as a dye, a bitter tonic, and a medicine for ailments from mouth sores to stomach complaints. The active compound is berberine, the same antimicrobial alkaloid found in goldenseal, and the roots produce berberine in striking quantity. Xanthorhiza is Greek for yellow root, and the name is no metaphor.
A native lily that answers the rain. Zephyranthes atamasco, the atamasco lily or rain lily, is a bulbous perennial of the amaryllis family, native to moist woods and meadows of the Southeastern United States. The name atamasco comes from the Powhatan people of the Virginia tidewater, an old word carried into botany, and the plant has also long been called Easter lily for the season of bloom.
