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.
A graceful native onion, Allium cernuum, the nodding onion, lifts loose clusters of pink to lavender, bell-shaped flowers that bend over in a soft arc at the top of slender stems, swaying through mid and late summer above tufts of grassy, blue-green foliage. The nodding habit gives the plant a particular charm, and the flowers draw native bees, butterflies, and other pollinators in good numbers.

Sweet almond verbena is grown for one glorious thing above all: scent. From midsummer until hard frost, Aloysia virgata tips every branch with slender spikes of small white flowers that pour out an intoxicating vanilla-almond fragrance, strongest in the late afternoon and evening and carrying clear across a garden. Butterflies and hummingbirds work the spikes all season.
Ampelaster carolinianus is a woody, scrambling, semi-evergreen vine that climbs through shrubs and over stream banks along the coastal plain of the southeastern United States, opening lavender-blue flowers in November and December when every other aster has long since finished. The climbing aster keeps a private schedule, and that contrary timing is the whole charm.
Few vines work as hard for as little as the coral vine. Antigonon leptopus comes out of Mexico with heart-shaped leaves, tendrils that grab any small object within reach, and long sprays of small papery flowers in a hot, slightly unreasonable pink from midsummer until frost stops the show. The flowers are borne in such quantity that the whole plant seems to fizz, and the common names have piled up accordingly: coral vine, queen's wreath, Mexican creeper, chain of love, and, in the Gulf South, confederate vine. Bees find the plant before you do.
Swamp milkweed brings beauty and biodiversity to the moist garden. Asclepias incarnata is a native perennial prized for domed clusters of rosy pink, vanilla-scented flowers and for a vital role in feeding pollinators, native to wet meadows, streambanks, and lowland prairies across much of North America. The plant takes happily to rain gardens, wet soils, and sunny borders alike, a natural for the ecologically minded gardener.
Hardy begonia is the surprise of the shade border: a true begonia that survives a cold winter. Begonia grandis carries large, pointed, olive-green leaves lit with red veins and flushed deep rose-red beneath, and in late summer and fall hangs loose clusters of soft pink flowers on red-tinted stems, a cool, luminous note when most shade plants have finished.
Crossvine is a high-climbing, semi-evergreen native vine with bright trumpet flowers, and 'Helen Fredel' is a large-flowered selection in red-orange with a yellow throat, a shade between the old varieties 'Atrosanguinea' and 'Tangerine Beauty'. Climbing high by tendrils and adhesive holdfasts, the crossvine flowers heavily in early summer and again, more lightly, later, and shows to best effect on a fence, an arbor, or a trellis in sun or part shade.
Crossvine is a high-climbing, semi-evergreen native vine, and 'Tangerine Beauty' is the famous tangerine-orange selection, opening a spring blaze of bright orange, trumpet-shaped flowers and blooming again, more lightly, through the season. Climbing high by tendrils and adhesive holdfasts, the crossvine shows to best effect on a fence, a wall, or a trellis in sun or part shade, where the early trumpets draw hummingbirds in numbers.
Crossvine is a vigorous, semi-evergreen native climber that ascends by tendrils and adhesive holdfasts, and var. atrosanguinea is the red one: where the typical crossvine flowers orange, this striking selection, introduced by Woodlanders, carries abundant deep red to red-purple trumpets, often over narrower, longer leaves. The flowers even smell faintly of mocha on a warm day.
Bouvardia ternifolia, the firecracker bush, is a compact, heat-loving shrub of the southwestern United States and Mexico, hung from late spring to frost with clusters of long, slender, scarlet-red tubular flowers. Few plants pull hummingbirds in like this one: the bright tubes are pitched exactly for their bills, and the bloom keeps coming through the hottest months when little else holds color.
Buddleia alternifolia, the fountain or alternate-leaf butterfly bush, stands apart from the usual butterfly-bush crowd. A deciduous shrub native to northwestern China, the fountain butterfly bush is the most cold-hardy of the genus, and is grown above all for a weeping form and an early-season flood of fragrant, lavender-purple bloom.
Buddleia lindleyana, Lindley's butterfly bush, is the elegant outlier of the genus, an open, arching shrub from China hung in summer with long, slender, gracefully curved racemes of purple-violet flowers. Where most butterfly bushes carry stiff cone-shaped panicles, this one drapes, the curving spikes nodding from the tips of the branches from June until frost.
Buddleja salviifolia, the sage-leaf butterfly bush, is a medium to large evergreen shrub from the sun-soaked hillsides of South Africa, and despite the exotic origin the plant has proven remarkably hardy in southeastern gardens, coming through winters at the University of Georgia's Athens trials with quiet resilience.

Few hardy shrubs put on a show like Caesalpinia gilliesii, the desert bird of paradise, whose summer flowers open clear yellow and send out a spray of long scarlet stamens like fireworks caught mid-burst. A legume from the dry country of Argentina and Uruguay, long naturalized across the American Southwest, the plant carries ferny, blue-green, mimosa-like foliage that sets off the flamboyant bloom. Botanists now place the species in the genus Erythrostemon, meaning red stamen, though gardeners still know the plant as Caesalpinia.
Callerya reticulata, the evergreen wisteria, is one of the most graceful vines for the Southern garden, and one of the most refined. Once known to botanists as Millettia reticulata and Wisteria reticulata, this evergreen climber is not a true wisteria, though the cascading habit and aristocratic bearing recall one. A vine for porches and pergolas, the evergreen wisteria prizes quiet bloom over brash spectacle, and carries both fragrance and folklore in the tendrils.
The genus name says it: Callicarpa, from the Greek kallos, beauty, and karpos, fruit, beautiful fruit, a genus named for exactly what it does. Callicarpa americana, the American beautyberry, is the southeastern native that gives the genus a calling card. From late August into November, the plant sets dense clusters of small drupes in a luminous magenta-purple, a color that registers as almost unreal in the late-summer landscape, somewhere between fuchsia and amethyst, with no real precedent among native fruits. The berries gather in tight whorls around the stem at every leaf node, all the way down the arching branches, so that a mature shrub in October looks less like a shrub bearing fruit than a ribbon of purple glass beads strung along the branches.

Callicarpa americana 'Bok Tower' is the white-fruited form of the American beautyberry, swapping the species' electric magenta for clusters of clean, pearly white berries that ring the arching stems in late summer and fall. The pale fruit is cool and luminous, lovely against the green leaves and a striking foil to the purple-berried kinds, and just as good for the birds.
'Profusion' is the beautyberry that finally made the genus behave. A Dutch selection out of Callicarpa bodinieri var. giraldii, a deciduous shrub from west and central China, this clone was chosen for one quality above all: fruit, in quantity, on a young plant, without needing a second shrub nearby to make it happen. Upright arching canes reach eight to ten feet, carrying bronze-purple new growth that shifts to pinkish purple in autumn. Small lilac-pink flowers open at the end of summer, unremarkable and much loved by bees. Then in October the point of the whole thing arrives: tight clusters of berries in a violet so saturated and so metallic that first-time visitors routinely assume the shrub has been sprayed. The berries hold on long after the leaves have gone, which is exactly when a garden needs them.
Callicarpa formosana, the Taiwan beautyberry, is a handsome deciduous shrub that lines the stems with vivid purple berries in fall, the clusters glowing against the fading leaves for strong late-season color. Native to Taiwan and southern China, the Taiwan beautyberry is built for warm climates and keeps a fuller, more robust frame than the smaller Asian beautyberries.
The weeping bottlebrush is the one most Americans have already met without knowing the name, a small tree of crimson brushes and long hanging branchlets planted through Florida and the Gulf Coast until a hard freeze thins the ranks and somebody plants them again. In the wild Callistemon viminalis runs down the eastern edge of Australia from Cape York into northeastern New South Wales, and almost always along water: creek banks, seasonal channels, the damp sand beside a watercourse. That habitat explains the two things that set this species apart from the rest of the genus. The branches hang rather than stand, giving the whole tree a fountain habit that carries even out of flower, and the roots will tolerate heavier ground and less than perfect drainage, which almost no other bottlebrush will.
