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.
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.
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 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.
This Phoebe is a broadleaf evergreen tree in the laurel family, Lauraceae, and a relative of the redbay and the avocado in the genus Persea. The genus Phoebe gathers more than fifty species of evergreen trees and shrubs across subtropical and tropical Asia, long known in China as nanmu and prized for hard, fine-textured, aromatic timber used in fine furniture and building since ancient times.
Photinia integrifolia is a handsome broadleaf evergreen, a small tree or large shrub of the rose family, widespread through the hills of southern and southeastern Asia, from the Himalayas and the Western Ghats of India east into Southeast Asia, yet virtually unknown in American gardens. A relative of the familiar Chinese photinia (Photinia serrulata), the species carries the same glossy, leathery foliage but with untoothed, entire-margined leaves, the trait behind the epithet integrifolia.
Physostegia virginiana, the obedient plant, is a familiar native of moist meadows and streamsides across eastern North America, and 'Vivid' is the compact, richly colored selection that has become a garden standard. Upright spikes of deep rose-pink, tubular flowers rise on square, mint-family stems in mid to late summer, holding strong color into early fall when much of the border is fading.
Pieris phillyreifolia, the climbing fetterbush, is one of the strangest and most wonderful of Southeastern natives, an evergreen member of the heath family with a habit unlike any other hardy shrub. In cultivation the plant grows as a neat, small evergreen shrub of two to three feet, clothed in narrow, leathery dark green leaves about an inch long.
Pieris ryukyuensis is the lily-of-the-valley shrub of the Ryukyu Islands, the warm archipelago that trails south from Japan toward Taiwan, and 'Temple Bells' is a choice selection of this heat-tolerant species. The glossy, slightly toothed evergreen leaves emerge a warm bronze and mature to deep green, giving a polished, year-round presence on a dense, rounded frame of three to six feet.
Piloblephis rigida, wild or Florida pennyroyal, is a compact evergreen native mint from the sandy scrublands and pine flatwoods of Florida. The plant forms a low, tidy mound of fine, needle-like foliage that carries a clean, resinous, minty fragrance, released at a brush of the hand or on a warm afternoon in the sun.

Pinus patula is the weeping pine, and few conifers wear their needles so gracefully. Long, slender, and soft, the bright grass-green needles hang straight down from the branches in feathery curtains, so that the whole tree seems to pour toward the ground, especially in a light breeze. Fast-growing and open-crowned, this is a Mexican pine grown above all for that pendent, shimmering foliage.
The Himalayan white pine is one of the most graceful of the large conifers, a broad, elegant tree hung with long, soft, blue-green needles that droop from the branches in feathery sweeps. Borne five to a bundle in the manner of the white pines, the needles give the whole tree a silvered, weeping softness, and the long, resinous, banana-shaped cones dangle among them like ornaments.
Pithecoctenium cynanchoides, the monkey's comb, is a vigorous, tendril-climbing vine of the trumpet-creeper family, Bignoniaceae, native to the warm woodlands and thickets of South America. Semi-evergreen in mild climates, the vine climbs by many-branched tendrils and clothes a support quickly in heart-shaped, three-parted leaves, the terminal leaflet often turned into a grasping tendril of its own.
Pleioblastus distichus 'Mini' is the smallest of the running bamboos, a fine-textured dwarf that behaves more like a groundcover than a grove. The tiny, glossy leaves line up in flat, two-ranked sprays, fern-like and neat, on threadlike stems only eight or ten inches high, building a dense green carpet that can be mowed or edged like a lawn.
