Smooth sumac is a bold, colony-forming native shrub of the eastern and central United States, in time reaching the scale of a small tree, and one of the finest plants going for a hot, dry, sunny site where little else will thrive. The long, pinnately compound leaves give an almost tropical texture through summer, and the plant spreads by root suckers into broad, picturesque colonies, or can be held to a single tree-like specimen where the suckers are controlled.

Staghorn sumac is a bold native shrub or small tree of the northeastern United States and Canada, growing fifteen to thirty feet on stout, forking stems clothed in fine velvety hairs, the texture and antler-like branching that give the plant the name. The big, pinnate leaves are bright green through summer and turn a spectacular blend of yellow, orange, and red in fall, one of the great autumn shrubs of the eastern flora.

Rohdea japonica, the sacred lily or Nippon lily, is a bold, slow, tufted evergreen perennial grown above all for foliage, and this selection carries the darkest leaves of all, an almost black, glossy green that anchors a shaded planting through the whole year and lights up a winter landscape when little else holds. Rather sizeable red berries ripen in tight clusters, half-hidden at the base of the leaves, a quiet second season for anyone who looks closely.
Rosemary is a timeless classic in both the garden and the kitchen, an aromatic evergreen shrub of the sun-baked Mediterranean coast, so distinctive that botanists long kept rosemary in a genus apart, Rosmarinus officinalis, before recent study moved the herb into the sages as Salvia rosmarinus. The old genus name means dew of the sea, for the plant's love of bright, salt-swept coastal hillsides. Slender, needle-like, deep green leaves clothe the woody stems the year round, and soft blue flowers open along them from winter into spring.

Rudbeckia fulgida var. fulgida is the true orange coneflower, the wild species that stands behind the famous 'Goldsturm', quieter, finer, and later to bloom than that celebrated garden child. From a low clump of dark, roughly hairy leaves rise branching stems two to three feet tall, each ending in a small golden daisy about two inches across, the deep yellow rays set around a low dome of brown-black. Where many of the black-eyed Susans have blazed and faded by August, the orange coneflower is only getting started, carrying many small flowers from late summer well into October.
Rhaphiolepis umbellata is the hardiest of the Yeddo hawthorns, an evergreen member of the rose family (Rosaceae) that grows wild on the sea cliffs and coastal thickets of Japan and Korea. The genus name joins the Greek raphis, a needle, with lepis, a scale, a nod to the narrow bracts beneath the flower clusters, while the species epithet umbellata describes the way the blossoms gather into rounded, umbel-like heads. Western gardeners know the shrub as Indian hawthorn, a slightly misleading name, since the plant hails from East Asia rather than the subcontinent and is no true hawthorn at all.
Fragrant sumac is a versatile deciduous shrub native across much of the eastern and central United States, where the plant threads scattered woodlands, rocky slopes, and open banks. The trifoliate leaves, often mistaken at a glance for poison oak, are entirely harmless, and a crushed leaf releases the clean, lemony-resinous scent that gives the plant every one of the common names, from fragrant sumac to skunkbush, depending on the nose. The genus name Rhus is the old Greek and Latin word for the sumacs, and the epithet aromatica names the scent directly.

Ruellia caroliniensis, the Carolina wild petunia, is a modest, long-blooming native that carries far more ecological weight than the quiet flowers suggest. From early summer into fall, a steady succession of lavender to violet-purple trumpets, each an inch or two across and lasting only a single day, opens along upright stems a foot or two high, replaced faithfully the next morning so that the plant is seldom out of bloom for months on end.
Ruscus aculeatus, Butcher's Broom, is a low evergreen shrub of the asparagus family, native to the woodlands of southern Europe, the Mediterranean, and the Middle East, and reaching north into the milder parts of the British Isles. What look like glossy, spine-tipped leaves are not leaves at all but flattened stems called cladodes, which take over the work of photosynthesis while the true leaves are reduced to tiny scales. The generic name comes from the Latin ruscum, the old word for a butcher's broom, and the epithet aculeatus means prickled, for the sharp point that tips each cladode.
