Plants that turn their faces to the light. This is the roll call for the open, sun-struck parts of the garden, the borders and banks that bake from morning to evening, where the toughest, brightest, most floriferous plants do their best work.
To see Styrax japonicus properly you have to look up. The leaves ride along the tops of the branches, all turned to the sky, while underneath, in late spring, hang rows of small white bells on slender stalks, so the whole horizontal tier of the tree seems lit from below. Stand beneath one in bloom and the common name explains itself.
The Sunquat began as an accident in a Beeville, Texas dooryard in the early 1940s, when a man named Leslie Cude noticed a seedling carrying fruit that looked like a small lemon and behaved like a kumquat. Walter Swingle, the great citrus authority of the day, took one look and guessed a cross of Meyer lemon and kumquat, which is where the name Lemonquat comes from and how it entered the collections as Citrus limon × Fortunella. The trouble is that the curators who have kept the tree at Riverside ever since have come to doubt him. The fruit, they think, points to a mandarin somewhere in the parentage rather than a lemon, which would make the plant a mandarinquat wearing the wrong label. Nobody has settled the question. The plant has gone out as Sunquat, Lemonquat, Lemondrop, and Marmaladequat, four names for one tree, each a different theory and not one of them proven. Asking a citrus to hold still long enough to be classified rather misunderstands the family.
Symphyotrichum oblongifolium, the aromatic aster, saves the best of the season for last. Long after most perennials have folded, this tough native throws up a low, spreading mound of stiff, well-branched stems and buries the whole clump under small violet-blue daisies, each lit with a bright gold eye, from early fall well into November. The show arrives just as the garden goes quiet, and the flowers hum with the last bees and butterflies of the year.
Bald cypress is the great deciduous conifer of the southern swamp, a long-lived, stately tree of river margins, bottomlands, and blackwater sloughs across the southern United States, and one of the most beautiful native trees the region has to offer. Soft, feathery, two-ranked needles clothe the branches in a light, bright green through summer, then turn a warm russet-orange and fall, leaving a broad, pyramidal frame bare for winter.
A Victorian-era English selection of one of the great trees of North America. The species, Thuja plicata, the western red cedar, is the dominant conifer of the Pacific Northwest coastal rainforest, the tree that towers 150 to 200 feet above the forest floor in old-growth stands of British Columbia, Washington, Oregon, and northern California, with individual specimens documented at over a thousand years old. To the Coast Salish, Haida, Tlingit, Kwakwaka'wakw, and other Pacific Northwest Indigenous peoples, western red cedar is the Tree of Life: the wood used for longhouses, dugout canoes, totem poles, and ceremonial regalia; the bark woven into baskets, mats, capes, and dress; the whole tree a structural and cultural foundation for thousands of years. That natural rot-resistance comes from the same volatile terpenoids that give the crushed foliage a sweet, cedary fragrance, the smell of the Pacific Northwest forest itself.
Tibouchina granulosa, the purple glory tree, is a Brazilian showstopper long grown in Florida and the warm South, a large shrub or small tree in frost-free gardens and a root-hardy dieback perennial where winters brush freezing. Glossy, deeply pleated, prominently veined leaves set off the flowers, which come smaller but far more abundantly than those of the better-known princess flower, Tibouchina urvilleana, so the whole plant seems dusted with purple through the warm months.
This variegated form of Confederate jasmine, or star jasmine, is grown as much for the foliage as the flowers. Each leathery, evergreen leaf is bordered and splashed with creamy white, often flushed pink in cool weather, and the leaves run larger than on most forms of Trachelospermum jasminoides, so the vine reads as a soft, marbled cloud of green and cream on a fence or trellis even out of bloom.
This is a Trachelospermum, one of the star jasmines, offered here as an unnamed selection. Like others in the genus, the plant is a twining, self-clinging evergreen vine with glossy, leathery, dark-green leaves that clothe a fence, trellis, or arbor in dense green through the year and take readily to clipping into a clean, structured cover.
Blue vervain rises in summer as a candelabra of slender, pencil-thin spikes, each one lit from the base upward with tiny, five-lobed flowers in a saturated purplish blue that few native perennials can match. Verbena hastata is a clump-forming perennial of eastern North America, reaching two to four feet in good ground and occasionally stretching to six, on stiff, square, hairy stems that branch toward the top. The lance-shaped leaves are sharply toothed and rough to the touch, a coarse green foil for the refined flower spikes above. Bloom comes slowly and deliberately from July into September, only a few florets open on each spike at any moment, so the plant seems to smolder for weeks rather than flare all at once.
Ironweed earns the name twice over. The stems are stiff enough to stand through a hurricane season without staking, and the seedheads that follow the flowers rust to the exact color of weathered iron. But the reason to grow Vernonia noveboracensis is the purple: not the tidy lavender of garden asters but a saturated, almost fluorescent violet that arrives in late July and holds into October, riding five to eight feet up on strong green stems above a mass of long, finely toothed leaves. Few native perennials carry a color this pure so late in the year.
'Chindo' is a bold, glossy-leaved evergreen viburnum, a vigorous selection grown for both ornamental drama and Southern toughness, hung in season with cascading clusters of brilliant red fruit. Few broadleaf evergreens offer this combination of shine, structure, and seasonal display at so substantial a scale.
The cinnamon-leaf viburnum is one of the great broadleaf evergreens of the genus, a substantial, dignified shrub from the mountain forests of western China, where mist gathers in the valleys and plants grow with quiet endurance. The species name cinnamomifolium means leaves like cinnamon, for the large, glossy, deeply triple-veined leaves that echo those of a true cinnamon tree, tooled and leathery as fine bookbinding. This is a plant that holds the line rather than blooms and fades with the hour.
Luzon viburnum is one of the quiet unknowns of Southern gardening, a handsome large shrub grown around Houston for years and almost nowhere else in the United States. Woodlanders collected this plant in the Houston area, where the species had already proven durable and undemanding in Gulf Coast heat. Viburnum luzonicum comes from open forest, scrub, and roadside thickets across southern China, Taiwan, Vietnam, and the Philippines, and the epithet points to Luzon, largest of the Philippine islands, from which Robert Allen Rolfe described the species at Kew.
They carry their Roman name almost unchanged. Tinus was what the Romans called the shrub two thousand years ago, the name Pliny the Elder set down in his Natural History, and when Linnaeus came to catalogue them he simply kept it. The reason gardeners have held onto Viburnum tinus just as long is that they flower in the cold. While the rest of the garden is shut down for winter, they cover themselves in tight clusters of deep carmine buds that open a few at a time across weeks into small white flowers, so they carry both colors at once through the bleakest stretch of the year. The foliage is the second argument, dense and dark and glossy, evergreen to the ground with none of the gapping that lesser shrubs fall into. 'Spring Bouquet' is the compact, well-behaved selection, rounding into a tidy four to six feet, which makes it the one to reach for when you want a hedge, a low screen, or a piece of evergreen structure that also happens to bloom in February. Metallic blue-black berries follow for the birds, set best when more than one plant grows nearby. They take shade, salt, and coastal wind without complaint. Few evergreens hand you this much in the dead of winter, which is precisely the season you'll be grateful for it.
Weigela is a deciduous shrub of rounded habit and opposite oval leaves. This cold-hardy old-fashioned favorite is native to eastern Asia. 'Java Red' is an old variety also known as 'Foliis Purpureis'.
A native tree that bites back, and can numb a toothache. Zanthoxylum clava-herculis, the toothache tree or Hercules' club, is a small to medium deciduous tree of the citrus family, native along the coastal Southeast from Virginia to Florida and Texas. The genus name Zanthoxylum means yellow wood, and the species clava-herculis, the club of Hercules, names the stout, spiny, club-shaped trunk that is the tree's signature.
A rain lily that flowers on a whim of the weather. Zephyranthes fosteri, Foster's pink rain lily, is a bulbous perennial of the amaryllis family, native to Mexico and hardy in the warm South, grown for vivid, crocus-like pink flowers that appear as if overnight after summer and autumn rains.
Woodlanders has long been a leader in offering citrus and citrus hybrids hardy well beyond the usual citrus belt, and the 'Razzlequat' is one of the odder and hardier of the lot. The plant is a cross between the Australian desert lime, Eremocitrus glauca, a tough, drought- and cold-tolerant native of the arid Australian interior, and, most likely, the familiar 'Meyer' lemon. From the desert lime parent come thorny, wiry branches, small narrow gray-green leaves, and a hardiness and drought tolerance rare among citrus; from the lemon come size and flavor.
A cold-hardy citrus with a Woodlanders pedigree. Woodlanders has long led in offering citrus and citrus hybrids that stand outdoors beyond the usual citrus belt, and the calamandarin is one of the toughest. Likely a hybrid of a mandarin, Citrus reticulata, and a calamondin, the calamandarin blends easy-peeling, tangerine-like fruit with the cold tolerance that calamondin brings to the cross.
