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.
Podocarpus macrophyllus, the yew pine, is a familiar evergreen conifer grown as a shrub or small tree across the southern United States, valued for dense, dark, strap-like leaves several inches long and a tidy, upright frame. 'Okina' is the variegated form, a relatively recent introduction from Japan, whose new growth emerges creamy white before settling to soft green.
This low-growing form of Podocarpus macrophyllus is a compact, spreading evergreen with flat, needle-like leaves that spiral tightly around the stems. Where the ordinary yew pine climbs into an upright shrub or small tree, this selection stays low and horizontal, building a dense, glossy green mat of steady year-round texture and structure.
A spring-blooming native of the eastern woodlands, found from Ontario and Quebec south through the Appalachians and as far west as Minnesota and Oklahoma, growing on rich deciduous forest floors, along streambanks, and at the bases of sandstone canyons. Polemonium reptans is one of those native plants that rewards close attention. The leaves are pinnately compound, with seven to twenty-one paired leaflets running up each stem like the rungs of a ladder, the source of the common name, which gestures all the way back to the biblical Jacob and his dream of a stairway to heaven. The genus name is older still: Polemonium honors King Polemon of Pontus, an ancient Greek ruler with a side interest in herbalism.

Poliomintha longiflora is one of the several aromatic plants that go by the name Mexican oregano, and one of the prettiest, a small evergreen shrub that flowers for months and seasons the pot besides. Slender, aromatic leaves clothe a rounded bush two or three feet high, and from spring well into fall the branches carry long, tubular flowers in soft lavender and pink, a steady supply of nectar in the heat when little else blooms.
Polygonatum commutatum, the great or giant Solomon's seal, is a bold native perennial of the eastern North American woodlands, sending up tall, unbranched, gracefully arching stems clad in broad, oval, alternate leaves. From the leaf axils along the underside of each stem hang small, creamy-white, bell-shaped flowers, usually in pairs, in late spring and early summer.

Polygonatum odoratum 'Variegatum', the variegated Solomon's seal, is one of the most graceful of all shade perennials, an Old World cousin of the native Solomon's seals grown for luminous, cream-edged foliage on arching stems. Each lance-shaped leaf carries a soft green center rimmed and streaked in creamy white, and the new stems flush a warm rose before greening.

Polyspora axillaris, the fried egg tree, is a glossy, small evergreen tree or large shrub of the tea family, Theaceae, native to southern China, Taiwan, and Vietnam and still rarely cultivated in the United States. A close relative of the native loblolly bay (Gordonia lasianthus), the plant bears abundant, showy white flowers three inches across.
Picture a midnight-green fountain unfurling in a woodland garden: that is Polystichum polyblepharum, the Japanese tassel fern. Native to Japan and South Korea, this evergreen fern forms elegant, shuttlecock-shaped clumps of glossy, bipinnate fronds to eighteen or twenty-four inches tall and wide, bringing shimmering texture and structure to shady corners. In spring the fiddleheads twist back on themselves, like silk tassels, before straightening into perfectly arching blades, lending a touch of theatrical grace to the early-season garden.
