The plants that come back. Herbaceous perennials rise from the crown each spring, flower through the warm months, and retreat to the ground in winter, returning larger the year after. They are the flowering heart of the border, the long-term investment that repays a gardener season after season.
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.
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.
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.
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.
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.

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.

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.

If any native perennial could be said to hum, the honor would go to Pycnanthemum muticum. From mid to late summer the blunt mountain mint gathers a shimmer of broad, silver-frosted bracts at the top of every stem, and within them open dense heads of tiny pink-to-white flowers that draw an almost comic density of life: bees of every kind, wasps, butterflies, skippers, moths, and flies working the nectar from dawn to dusk. In a three-year Penn State study that monitored eighty-six species, no plant drew a greater number and diversity of pollinators.
Rudbeckia nitida is a tall, luminous coneflower that trades the coarse hairiness of the common black-eyed Susans for smooth, glossy, dark green leaves and hairless stems, the shining foliage that gives the species a name. From a leafy base rise slender stems three to five feet tall, each carrying a large yellow daisy whose soft rays droop back from a raised, greenish-brown central cone, blooming through the heat of mid to late summer.
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.
Ruellia coccinea belongs to the acanthus family and comes from the Caribbean, native to Puerto Rico and the Virgin Islands, where the plant grows as a scarlet-flowered subshrub in warm, humid woodland. The Spanish common name, Yerba Maravilla, reads roughly as marvel herb, a fitting nod to the near-constant show. Through the whole of summer R. coccinea produces slender tubular flowers about an inch long, each opening into five spreading scarlet lobes, borne in clusters from the upper leaf axils and unfurling in succession from early summer until the first frost.
Salvia 'Phyllis Fancy' is a vigorous, large hybrid sage with a good pedigree, found as a chance seedling at the University of California, Santa Cruz Arboretum and named for a longtime volunteer there. The parentage is thought to involve Salvia leucantha, the Mexican bush sage, and possibly Salvia chiapensis, though the cross has never been confirmed.
'Cherry Queen' is a North Carolina-bred salvia from one of the most important salvia hybridizers America has produced. The cross is a deliberate one, between Salvia greggii, the autumn sage of the Texas and Mexican borderlands, prized for drought tolerance and a six-month bloom, and Salvia blepharophylla, a Mexican species whose name, eyelash-leaved sage, comes from the tiny fringe of hairs at the edge of each leaf (Greek blepharon, eyelash, and phylla, leaves). Blepharophylla carries the most saturated, signal-bright red flower in the whole genus, but the plant spreads by stolons in ways most gardeners do not want and resents cold winters, while greggii brings the bones and the durability. The breeder who put the two together was Dr. Richard "Rich" Dufresne of Candor, North Carolina, an organic chemist who became, more or less by accident, the leading American breeder of woody salvias for the eastern climate. Dufresne died in December 2018, leaving a body of work that includes 'Cherry Chief', 'Maraschino', and this selection, which Plant Delights Nursery called the most brilliant red they had ever seen on any hardy salvia.
Here is a salvia that wants what salvias are not supposed to want. Most of the genus comes from sunbaked Mediterranean hillsides, dry Mexican mountains, and dusty California chaparral, so that the very word Salvia is shorthand for full sun, gravelly soil, and a watering regime closer to neglect than care. Salvia koyamae, endemic to the cool wooded slopes of Honshu in Japan, breaks every rule, asking instead for shade, moist humus-rich woodland duff, and the cool morning light that filters through a deciduous canopy. This is, in short, the salvia to grow where hostas would otherwise go.
Salvia leucantha, the Mexican bush sage, is one of the great fall salvias, grown for arching wands of flower that seem spun from felt. Long spikes rise above the foliage in late summer and fall, densely packed with velvety purple calyces from which small white corollas emerge, a soft two-tone effect that catches low autumn light and holds for weeks. Few plants close the gardening year with such generous, easy color.
Salvia leucantha 'Midnight' is the all-purple form of the Mexican bush sage, and the difference is worth seeing. Where the common kind carries small white corollas against purple calyces, 'Midnight' drops the white altogether, so the long arching spikes read as pure, saturated purple from calyx to flower, a deeper and more solid color that carries even further across an autumn garden.
Salvia 'Anthony Parker' is a big, late-blooming hybrid sage with a charming South Carolina origin. The plant arose as a chance seedling in the Beaufort garden of the plantswoman Frances Parker, a cross between Salvia leucantha 'Midnight' and the pineapple sage Salvia elegans, and Frances rescued the young seedling from the path of the mower and named it for her grandson Anthony, then a year old, in 1994. From that lucky reprieve came one of the best late-season salvias for the South.
Salvia madrensis, the forsythia sage, is a big, robust perennial from the mountains of Mexico, grown for a late-season show of soft yellow. Broad, quilted, triangular leaves clothe stout, square, mint-family stems, and in fall the plant lifts terminal clusters of clear yellow flowers that recall a forsythia in bloom and give the sage its common name, an unusual color and a welcome one so late in the year.
Salvia mexicana, the big blue Mexican sage, is a tall, dramatic perennial grown for deep, saturated blue-violet flowers that arrive when the gardening year is winding down. The tubular blooms, set in contrasting calyces, are carried in long spikes above bold, heart-shaped leaves, and few plants bring so pure and deep a blue to the autumn garden.
