This seemingly unlikely hybrid crosses the familiar mountain laurel (Kalmia latifolia) with the diminutive, far less known sandhill laurel (Kalmia hirsuta) of the Deep South, two species that could hardly look more different. The cross was probably first made by the late, great Alabama nurseryman Tom Dodd, Jr., and further investigated by the Connecticut Kalmia expert Dr. Richard Jaynes, whose lifetime of work did more than anyone's to bring the genus into gardens.
Kerria is a monotypic genus, a single species that stands alone in the rose family (Rosaceae), native to the mountain woodlands of China and Japan. The old-fashioned kerria has bright green, arching stems and toothed leaves, and in spring the branches light up with flowers that in the common double form look like tiny golden roses. The genus honors William Kerr, the Kew plant hunter who sent the double-flowered form back to England from Canton in the early 1800s, and in Japan the plant is beloved as yamabuki, a name woven through centuries of poetry celebrating that spring yellow.
William Kerr arrived in Guangzhou in 1803 as the first professional plant hunter posted permanently in China, dispatched by Sir Joseph Banks and the Royal Botanic Gardens at Kew to send back whatever the southern port cities could offer. Among his returns was a double-flowered shrub with bright yellow, pompon-like blooms, gathered from cultivation and shipped to Kew in 1805. The genus was eventually named Kerria in his honor. His later years were less distinguished, marked by an opium habit and a thinning correspondence, and he died in Ceylon in 1814. The double-flowered form he introduced, 'Pleniflora', went on to become one of the most common shrubs in Victorian gardens, present in nearly every collection of the era and still widely planted today.
The Chinese flame tree is a fast-growing, upright ornamental of coarse, handsome structure, casting medium shade and broadening with age into a rounded crown of twenty to forty feet. A member of the soapberry family (Sapindaceae) native to southern China, Koelreuteria bipinnata carries large, twice-pinnate compound leaves that give the canopy a light, ferny texture through the growing season before turning soft yellow in fall.
The goldenrain tree is a deciduous member of the soapberry family (Sapindaceae), native to China and Korea and long cultivated across eastern Asia. Growing to a rounded twenty-five to thirty-five feet, the tree carries handsome pinnate compound leaves that cast a light, dappled shade, and in early to midsummer, later toward the north, the branches hang with large, airy panicles of small golden-yellow flowers, a soft rain of gold across the crown and the source of the common name goldenrain tree.
'Woodlanders Low Form' is a rare, shrubby selection of the goldenrain tree (Koelreuteria paniculata), a compact form that trades the usual rounded canopy for a low, dense frame of ten to twelve feet. The elegant, pinnate compound leaves and the showy summer panicles of small, bright yellow flowers are all present, simply gathered into a modest footprint that suits a small garden far better than the full species.
Seashore mallow is an erect, branching herbaceous perennial of the cotton family (Malvaceae), the same clan as hibiscus, hollyhock, and cotton, and the kinship shows in the flowers. Native to the brackish and salt marshes of the eastern United States, from New York and Delaware south to Florida and Texas, the species carries hibiscus-like blooms from midsummer well into fall, each a clear five-petaled cup around a central column of fused stamens. This selection, 'Alba', trades the usual soft pink for pure, clean white.
Among crape myrtles, Lagerstroemia fauriei is the aristocrat grown as much for bark as for bloom. A small, multi-stemmed, deciduous tree from Yakushima Island in southern Japan, first brought to botanical attention in the 1950s, the species reaches a graceful twenty-five to thirty-five feet with a rounded, vase-shaped crown. The summer flowers are white, carried in airy terminal panicles that are smaller and more delicate than the heavy trusses of the familiar Lagerstroemia indica.
'Bayou Marie' is a compact crape myrtle from the Dixie Series, a group of dwarf selections, chosen by David Chopin of Washington, Pennsylvania and introduced by Hines Nursery in California, in the same series as the purple 'New Orleans'. The flowers are the draw: abundant clusters of crinkled, crepe-textured pink blooms, each petal finished with a darker red to lavender edge that gives the whole shrub a lively, two-toned sparkle through the heat of summer.
'New Orleans' is a purple-flowered dwarf crape myrtle from the Dixie Series, a group that Michael Dirr, in his Manual of Woody Landscape Plants, describes as the miniature weeping crape myrtles for their low, softly cascading habit. The summer flowers are the rich violet-purple that gardeners rarely find at this small scale, crinkled and crepe-textured, borne in profusion across a mound of no more than two to three feet.
'Pixie White' is a true miniature crape myrtle, a low, compact selection that trades the usual upright tree for a small, spreading, often weeping mound. Through the warm season the plant covers the fine green foliage with clear, clean white flowers, the crinkled, crepe-textured blooms that name the whole clan, at a scale that fits the smallest garden.
'Pocomoke' is one of the smallest crape myrtles in cultivation, a dense, dwarf mound released by the U.S. National Arboretum in 1998 from the breeding program of Dr. Donald Egolf. A hybrid of the common crape myrtle (Lagerstroemia indica) and the Japanese species (Lagerstroemia fauriei), 'Pocomoke' belongs to the group of Arboretum introductions named for Native American tribes and rivers, and carries the deep rose-pink flowers that set the selection apart at such a tiny scale.
The Lakeland limequat is a citrus lover's answer to cold: a compact, productive hybrid that pairs the hardiness of the kumquat with the bright, tropical punch of Key lime. One of three limequats bred by W. T. Swingle of the U.S. Department of Agriculture in Florida in 1909 and named for the town of Lakeland, this cross (Citrus x floridana) joins the West Indian, or Key, lime with the round Marumi kumquat (Fortunella japonica). The result carries intense citrus flavor on a plant that thrives well beyond the usual citrus belt.
Few tender shrubs work as hard for as long as the lantanas, and Lantana camara 'Hybrida' distills the whole genus down to a single clear note of yellow. The species belongs to the verbena family, Verbenaceae, and hails from the West Indies and the warm reaches of Mexico south through tropical America, where the plant scrambles along roadsides and clearings in a haze of nectar and butterflies. The genus name is a borrowed one: Renaissance botanists lifted 'Lantana' from an old Latin name for the wayfaring tree, Viburnum lantana, whose domed flower clusters the lantana blooms happen to echo. The epithet camara is murkier, glossed variously as a vaulted chamber or a small boat, the true meaning long since lost to the record.
Every so often a plant arrives not from a breeder's bench but from a neighbor's yard, and Lantana camara 'Miss Huff' is one of those happy accidents. The selection was found in cultivation near Athens, Georgia, in the garden of the Miss Huff for whom the plant is named, and introduced to the trade by the former Goodness Grows Nursery. What set this lantana apart was cold tolerance: where most of the tribe sulk and die at the first hard freeze, 'Miss Huff' has proven the hardiest lantana in commerce, with well-established clumps shrugging off brief dips to a few degrees below zero and returning faithfully from the root even in zone 7.
Where the shrubby lantanas stand up, Lantana montevidensis lies down and travels. This is the trailing lantana, a low, weeping member of the verbena family, Verbenaceae, native to the warm grasslands of southern South America, from southern Brazil across Uruguay and Paraguay into Argentina. The species carries a place name in the epithet: montevidensis means of Montevideo, the Uruguayan capital near which the plant was first gathered and described, so the botanical name is really a small geography lesson tucked into Latin.
There are plants that offer fragrance, and then there are plants that conjure memory. Lavandula dentata, with silvery, sawtoothed leaves and near ever-blooming lavender plumes, belongs firmly to the second kind, a bearer of the sort of scent that lingers in a sun-warmed linen chest or in the folds of a well-worn book left on a porch rail.

Lavandula × intermedia is the lavender that finally makes sense of the Southeast. A natural and cultivated cross between English lavender (Lavandula angustifolia) and spike lavender (Lavandula latifolia), the plant is known in Provence as lavandin, and there the sterile, vigorous hybrid has long been the mainstay of the perfume fields, prized for a heavier yield of fragrant oil than either parent alone. The name records that middle ground: intermedia, intermediate, a lavender poised between the sweet refinement of the English kind and the camphorous punch of the spike.

Few late-summer plants command a border like Leonotis leonurus, the lion's ear of the South African veld. Tall square stems, the signature of the mint family, Lamiaceae, rise five feet and more before breaking into tier upon tier of burnt-orange flowers, each whorl circling the stem like a ruff. The velvety, curved tubes are the source of both common names, lion's ear and lion's tail, and the botany agrees: Leonotis comes from the Greek for lion's ear, and leonurus for lion's tail.

By late summer, when many shrubs have said their piece, Lespedeza thunbergii 'Spring Grove' is only clearing its throat. The many woody, arching stems bend into a green fountain through the season, then bow lower still under a long, generous fall of rose-purple pea flowers carried in racemes six to eight inches long. 'Spring Grove' is a newer selection said to hold darker purple flowers and a tidier, better habit than the old standard 'Gibraltar', and the photographs here come courtesy of the JC Raulston Arboretum.
