For most of botanical history the genus Parrotia was thought to hold a single species, the Persian ironwood (Parrotia persica) of the Caspian forests. Then came a small Chinese tree with a long and tangled paper trail. A fruiting specimen gathered in Jiangsu Province in 1935 sat in a herbarium drawer until 1960, when the botanist H.T. Chang described the specimen as a witch-hazel under the name Hamamelis subaequalis. The living tree, meanwhile, had vanished. The species was presumed extinct for half a century, until a 1988 expedition found the tree again, and only in the late 1990s did DNA settle the question once and for all: no witch-hazel at all, but a second Parrotia, sibling to the Persian across some 3,500 miles of Asia.
Passiflora caerulea is a vigorous evergreen vine climbing by tendrils. The leaves are deeply divided with narrow lobes. The flowers showy and intricate but ephemeral. Flowers three to four inches across and blue is typical for the species. This is a beautiful vine with striking flowers but can become rampant if not confined or restrained. It is native to Argentina.
Passiflora caerulea is a vigorous evergreen vine climbing by tendrils. The leaves are deeply divided with narrow lobes. The flowers showy and intricate but ephemeral. Flowers are three to four inches across and while blue is typical for the species 'Constance Elliott' is a white-flowered form. This is a beautiful vine with striking flowers but can become rampant if not confined or restrained. It is native to Argentina.
This is an herbaceous perennial vine climbing with tendrils. It has hairy lobed leave and 2 inch wide pink intricate flowers typical of Passiflora with feathery bracts beneath the flower. The vine is also noteworthy for the red fruits the size of small pullet eggs with the persistent bracts which hang on in fall as foliage dies down. An interesting vine for the sunny arbor or fence. We originally collected this as seed in San Antonio, Texas. Native to Central and South America and the West Indies but naturalized elsewhere in warm regions.
Few native plants look as improbable as the maypop. Passiflora incarnata, the wild passionflower of the American Southeast, opens intricate three-inch flowers of pale lavender and white, each ringed with a fringed corona of wavy filaments above a central column of stamens and styles. Spanish missionaries read the whole Passion of Christ into that structure, the corona for the crown of thorns, the five anthers for the wounds, the three styles for the nails, and gave the genus its devotional name. Common along field edges and roadsides from Virginia to Florida and west to Texas, the vine climbs by curling tendrils or sprawls across open ground.

Passiflora incarnata alba is the rare pure white form of the native maypop, the wild passionflower of the American Southeast. The flower keeps all the improbable structure of the species, an intricate three-inch bloom with a fringed corona above a central column of stamens and styles, but drained of every trace of lavender: white petals, white sepals, and a white corona, luminous and cool against the deep green foliage. The effect is a ghostly, refined version of a familiar roadside wildflower.

Passiflora 'Incense' is a passionflower bred for pure spectacle, an extraordinary cross between the native maypop, Passiflora incarnata, and the South American Passiflora cincinnata. The hybrid gathers the toughness of the native parent and the drama of the exotic one into a single deep-violet flower four to five inches across, the wavy corona filaments frilled and banded in purple and white, carrying a sweet, incense-like fragrance that gives the plant its name.
Passiflora 'Amethyst' is one of the most rewarding of the ornamental passionflowers, a vigorous hybrid grown for large, jewel-toned blooms of glowing red-purple. Each flower opens nearly flat, three to four inches across, the petals and sepals reflexing back to set off a short, banded corona and a lifted central column of stamens and styles. The parentage is somewhat uncertain, as with many old garden passionflowers, but the effect is unmistakable: an amethyst star held out along the vine.
Patrinia scabiosifolia 'Nagoya' is a tough, upright perennial from the meadows and grassy hills of East Asia, grown for airy, flat-topped heads of tiny golden-yellow flowers held high on wiry, branching stems. The species name scabiosifolia points to the deeply lobed basal leaves, which recall those of a scabious, and the whole plant reads as a chartreuse-gold answer to Queen Anne's lace, lending height and a see-through veil to a summer border. In Japan the species is one of the classic seven flowers of autumn, and 'Nagoya' is a garden selection prized for reliable, compact performance.
Patrinia villosa is a good perennial for warm climates, introduced to American gardens by Heronswood Nursery, and the appeal is easy to miss in a catalog photograph and obvious in a border. Broad flat clusters of small white flowers are held well clear of the foliage on wiry stems through summer, giving the effect of a white lace-cap floating above the planting rather than sitting in it. The basal leaves are coarsely toothed, ovate to rhomboid, and covered in the short white hairs that give the species its epithet. Plants run gently at the root, so a single crown widens into a colony over a few seasons without ever becoming a nuisance.
Penstemon digitalis is one of the most adaptable of the native beardtongues, a clump-forming perennial of moist meadows, prairies, and open woods across the eastern and central United States. 'Husker Red', selected at the University of Nebraska and named Perennial Plant of the Year in 1996, keeps all the toughness of the wild species but wears it in deep wine-red: a basal rosette of glossy maroon foliage that holds color from spring through fall.
This rare Penstemon is a very attractive perennial with deeply cut, fern-like leaves and tall spikes of pinkish-violet flowers, each two-lipped tube carrying the yellow-bearded sterile stamen that gives the genus the name beardtongue. The dissected foliage is not merely a nice feature; it is unique in the entire genus, and no other Penstemon anywhere in the world has leaves like these. Bloom comes in late spring on stems of a foot to two, held well above a low basal clump.
Small's beardtongue is one of the showiest and most obliging of the eastern native penstemons, a Southern Appalachian wildflower that carries tall spires of lavender-pink to rosy-purple tubular flowers in late spring and holds them for weeks. Each bloom is pale-throated and finely striped inside, a landing-strip for the bumblebees that work the flowers, and the whole plant rises from a handsome rosette of purple-veined foliage on reddish stems.
Persea borbonia, the redbay, is a handsome broadleaf evergreen native to the southeastern United States, ranging from coastal Virginia through Florida and west along the Gulf. A member of the laurel family and a close relative of the avocado, the redbay carries the same aromatic oils, and the glossy leaves have long been used in the southern kitchen much as bay laurel (Laurus nobilis) is, to season soups, stews, and gumbo.
Phlox carolina 'Kim' is among the best of the Carolina phloxes, a selection found by the plantswoman Jan Midgley in Alabama and grown ever since for good health and honest flower power. From a low, tidy clump of narrow, almost lime-green leaves rise sturdy stems eighteen to twenty-four inches tall, each carrying an open, airy cluster of pale to bright pink flowers, five petals apiece, hovering just above the foliage from late spring into early summer. Where the border phloxes so often finish the season spotted and tired, 'Kim' holds clean, fresh foliage from spring straight through fall.
Wild blue phlox turned up in the Woodlanders catalog almost by insisting on it, growing in the woods around Aiken the way the plant has for as long as anyone can remember. We have watched these colonies for years, and taking this long to offer them is either a comment on our patience or on our woody bias. Possibly both.
'Shortwood' is one of the best of the tall garden phloxes, a strong pink that stands up straight and blooms for weeks in the heart of summer. Each large, domed panicle is packed with fragrant flowers, clear rose-pink around a deeper magenta eye, and the whole plant reads from across the garden, four feet of upright color that never seems to flop.
Phlox pilosa, the downy or prairie phlox, is a native of open woods, prairies, and glades across much of the eastern and central United States, and 'Eco Happy Traveler' is one of the most rewarding garden selections, made for a spreading habit and a long run of clear rose-pink bloom. The soft, downy stems and narrow leaves give the plant the common name, and the whole low mat is topped in late spring by loose clusters of fragrant, five-petaled flowers.
Phoebe cavaleriei is a broadleaved evergreen of the laurel family, and one of the handsomest of them. The leaves are leathery, four to seven inches long, oblanceolate to obovate, deep glossy green above and a pale greenish white beneath, so the whole canopy changes color as the wind turns the foliage over. Crushed, the leaves give off a pleasant spicy scent, which is the family signature and the reason bay, cinnamon, and sassafras all count as cousins. The bark is reddish brown with fine longitudinal striations while the young branches stay green. Flowers come between May and July, yellow to yellowish white and barely an eighth of an inch long, followed by round fruits about half an inch across seated in persistent tepals. Nobody grows this tree for the flowers.
Phoebe chekiangensis is one of a group of Chinese evergreens that could give the American South a whole new kind of shade tree. Upright and clean-limbed, the tree carries dense, leathery, dark green leaves much like those of the related redbay, glossy and handsome the year round, and grows at a steady pace into a small to medium tree of real presence.
