For gardeners in a hurry. Fast-growing plants close the gap between a bare new garden and a full one, putting on real size in a season or two to give shade, screening, and structure while the slower, longer-lived plantings catch up.
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.
Salvia microphylla 'Deltoid' is a shrubby form of the littleleaf or baby sage grown for warm salmon-coral flowers and neat, triangular, deltoid leaves. The small tubular blooms open over a long season and read as a soft coral against the fine, glossy foliage, a gentler tone than the hot scarlet of many littleleaf sages.
Salvia microphylla 'Hot Lips' is the famous temperature-shifting bicolor of the littleleaf sages, and the trick is worth the fame. In the cool of spring the flowers may open pure white or pure red, but as summer heat builds they turn strikingly two-tone, white below with a bold red lip, so that a single plant can carry white, red, and red-and-white flowers all at once. The show runs from late spring until frost.
Salvia uliginosa, the bog sage, is an airy, sky-blue perennial grown for clouds of clear, cool blue flowers held on tall, slender, branching stems from midsummer into fall. The species name uliginosa means of marshes, and the plant lives up to it, thriving in the moist ground most sages refuse, so the bog sage fills a niche few others in the genus can.
Salvia urticifolia, the nettleleaf sage, is an uncommon herbaceous perennial native to the Appalachians and the wider Southeast, grown for cool blue-to-violet flowers set off by a pair of white marks in the throat. The bloom comes in the freshness of mid to late spring, the flowers hovering above serrated, nettle-like leaves, and in a generous year a lighter second flush may follow in late summer.
Peacock moss is not a moss at all but a very low, spreading fern relative, a spikemoss whose scale-like leaves clothe trailing stems that root as they run and knit into patches across moist, shaded ground. The great distinction of Selaginella uncinata is color: in good light the foliage takes on an iridescent, metallic blue-green sheen, the peacock shimmer that gives the plant a common name.
Palm grass earns the name at a glance. The broad, pleated blades of Setaria palmifolia fold and arch like the fronds of a young palm, bringing a lush, tropical boldness to a border that most grasses cannot match. This is a plant grown for presence and texture rather than flower, a bright green statement in beds, containers, and the wilder corners of a garden where form is welcome.
Cup plant is a giant of the summer prairie, a statuesque perennial that rises on stout, square stems to eight feet or more and lifts a crown of bright yellow, daisy-like flowers above the border. The name comes from a quirk of the foliage: the large, coarse leaves are perfoliate, joined in pairs around the stem to form a shallow cup that catches and holds rainwater. Silphium perfoliatum belongs to the sunflower tribe of the aster family, Asteraceae, and shares that clan's generosity of bloom.

Gesneriads are supposed to be houseplants. Somebody should tell Sinningia sellovii, which comes out of a hard woody tuber the size of a fist, throws arching stems three or four feet long, hangs them with scarlet tubular flowers from early summer until frost, and then dies back to the ground and does the whole thing again the following year in USDA zone 7b. Gardeners who know the family only through florist gloxinias tend to find this genuinely disorienting, which is a good reason to grow the plant near the front gate.
Florists across the South have a name for the green that turns up at every wedding worth attending and every Christmas mantel worth dressing: Jackson vine. Southern smilax, if that is how you came up. The town of Evergreen, Alabama took its name from this very plant, which gives you some idea how far Smilax smallii has wound itself into the region's notion of celebration. Looped down a staircase, run along an altar, drawn the length of a table, they are the foliage that announces something is happening here.
Stauntonia hexaphylla is a handsome, vigorous evergreen climber from the woodlands of Japan, Korea, and China, grown as much for glossy year-round foliage as for the famous fruit. The palmate leaves are cut into five to seven leathery, dark-green leaflets, held on a strong, twining vine that clothes a support densely from top to bottom. A member of the Lardizabalaceae, Stauntonia counts Akebia, the chocolate vine, and Decaisnea, the blue-sausage tree, as relatives.
Styrax obassia, the fragrant snowbell, is the bold-leaved cousin of the more familiar Japanese snowbell, a small deciduous tree from the mountain woodlands of Japan, Korea, and China. Where Styrax japonicus hides small bells beneath fine, layered branches, the fragrant snowbell wears large, rounded, almost tropical leaves up to eight inches across, and hangs long, drooping chains of white, bell-shaped flowers that carry a sweet perfume through the late-spring garden.
Copper Canyon daisy is a big, aromatic, autumn-flowering marigold from the mountains of southern Arizona and adjacent northern Mexico, grown as much for the scent as the show. Brush against the finely divided, fern-like foliage and the plant releases a strong, distinctive fragrance, a mix of citrus, anise, and marigold that some find intoxicating and others frankly pungent. Tagetes lemmonii builds a soft, shrubby mound three to four feet high and wider still.
Imagine a shrub that looks like a conifer caught in an airy, pink-flowering daydream. Tamarix ramosissima, often called tamarisk or saltcedar, is a deciduous shrub or small tree with fine, scale-like leaves that read as cedar from ten feet away, yet drop in winter. That contradiction is the charm: conifer-like texture on a plant that is no conifer at all.
American basswood is one of the great shade and honey trees of eastern North America, a fast, stately deciduous tree with large, heart-shaped, softly toothed leaves and a broad, rounded, generous crown. Tilia americana has been cherished by Indigenous peoples, European settlers, and naturalists alike, and goes by a string of names: linden, bee tree, and lime, though the tree is no relation to the citrus lime. In late spring and early summer, hanging clusters of pale yellow, sweetly fragrant flowers open and hum with bees.

'Madison' is the cold-hardy Confederate jasmine, the selection that carries the beloved evergreen vine a full zone north of where the tribe usually stops. Vigorous and twining, with glossy dark leaves and the powerfully fragrant, white, star-shaped flowers that make star jasmine famous, this form has proved hardy into USDA zone 7, well beyond the reach of the standard Trachelospermum jasminoides.
