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.
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.
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.
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.
Pinckneya is a large shrub or small deciduous tree with showy pink flowers that are not flowers at all. What carries the colour is a single enlarged sepal on some of the blooms, expanded into a soft rose-pink blade three or four inches long, so a tree in full display looks convincingly like a poinsettia that has escaped into a Georgia bog. The true flowers are smaller, greenish-yellow, tubular, and easy to overlook beside the bracts. The leaves are oval and four to five inches long, and the whole plant is loose and open rather than dense.
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.
