Osmanthus burkwoodii is one of the most reliable and sweetly scented of the spring evergreens, a dense, compact shrub that disappears under clusters of tiny white flowers in April and perfumes the whole garden around it. The small, dark green, leathery leaves are finely toothed and glossy, holding their color and structure through the year, so that the plant earns a place long after the fragrance has faded.
Osmanthus x fortunei 'Natchez' is a hybrid that takes the best of two parents. The cross joins Osmanthus fragrans, the sweet olive treasured for its perfume, with Osmanthus heterophyllus, the false holly valued for tough, spiny, evergreen foliage, and 'Natchez' inherits both gifts: a dense, glossy, holly-leaved frame and a flood of fragrance in fall. The hybrid takes the name of the old river town of Natchez, Mississippi, a nod to the Deep South gardens where these tea olives have long been at home.
Osmanthus x fortunei 'San Jose' is a large, upright member of Fortune's tea olive, the garden hybrid that crosses the false holly, Osmanthus heterophyllus, with the sweet olive, Osmanthus fragrans. Among the fortunei clones, 'San Jose' stands apart for thinner, more finely toothed leaves and a taller, more upright habit, a plant that reaches for height where others spread.
Osmunda regalis, the royal fern, is a plant of stature and quiet nobility, at home where the woods remember water and time moves slowly. The genus Osmunda gives its name to an ancient family, the Osmundaceae, sometimes called the flowering ferns, with a fossil lineage that reaches back past the Jurassic; a royal fern in the garden is a living relic of a far older flora. The natural range runs from Nova Scotia to Florida in North America, and on through Europe, Africa, and Asia, making this one of the most widely distributed ferns on earth. Both the common name and the Latin regalis salute the same quality: among the largest and most robust of all North American herbaceous plants, the royal fern reaches four to six feet where truly content.

Osteomeles schweriniae, the bone apple, is a refined evergreen shrub in the rose family, close kin to hawthorn, cotoneaster, and photinia, and a botanical rarity seldom seen in American gardens. The genus name joins the Greek osteon, bone, and melon, apple, a nod to the stony hardness of the little fruits, while the species epithet honors the German dendrologist Count Fritz von Schwerin. Native to the dry valleys and open slopes of Yunnan and western Sichuan in southwestern China, the shrub carries very small, ferny, pinnate leaves along dense, wiry, arching stems, giving a fine texture unusual among broadleaf evergreens.
Oxydendrum arboreum, the sourwood, is one of the loveliest and most distinctive trees of the Eastern American woods, and among the very last to flower each year. The name tells the story twice over: Oxydendrum joins the Greek oxys, sour or sharp, and dendron, tree, while the common name echoes the same tang, for the leaves, twigs, and bark all taste sourly of oxalic acid when chewed. A member of the heath family alongside azaleas, rhododendrons, and blueberries, sourwood stands alone as the sole species in the genus, native to well-drained, acid woodland soils from southern Pennsylvania to the Florida panhandle and west toward Louisiana, most abundant in the lower Appalachians.

There is a moment in late winter, before anything else in the garden has stirred, when Parrotia persica opens the first flowers. They have no petals, just a tight cluster of crimson stamens emerging from scaled buds along bare grey branches, small and startling against the cold. Most people walk past them. The ones who stop tend to become collectors.
Parrotia persica 'Lamplighter' is a rare variegated form of the Persian ironwood, grown above all for the foliage: each leaf carries a broad, irregular border of creamy white around a grey-green center, so the whole canopy reads as soft, dappled light through the growing season. New growth can flush pink and rose before the variegation settles, and the effect is luminous rather than loud, a tree that brightens a shaded corner the way a lit lamp does, which is presumably how the selection came by the name.
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.
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.
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.
