Hypericum densiflorum earns the name densiflorum, densely flowered, in high summer, when the twiggy shrub disappears under rounded clusters of small golden flowers, each one a starburst of fine stamens above five clean yellow petals. Bees work the blooms from July into September, and as the show fades the narrow dark green leaves turn a warm yellow, giving way in winter to reddish, lightly peeling bark on the older stems.
Hypericum edisonianum is a Florida endemic with an upright, colony-forming habit, sending up reddish-brown stems clothed in small, leathery, gray-green leaves and topped in the warm months with four-petaled yellow flowers, each brushed with a dense tuft of stamens. As the stems age the bark peels away in thin strips, a subtle textural detail on a shrub that spreads by clonal growth into a low thicket.
Hypericum kalmianum is the tidy, cold-hardy member of the clan, a compact rounded shrub barely knee-high, densely branched, with narrow bluish-green leaves set in pairs along curiously four-angled stems. From July into September the plant disappears under bright golden flowers, each a shallow cup filled with a full boss of stamens, the bloom arriving in the heat of summer when the color is most welcome.
Hypericum lissophloeus is the tree among the St. John's Worts, a graceful evergreen that climbs to ten feet or more on slender trunks dressed in smooth, copper-colored bark that peels in thin sheets. The leaves are needle-fine and deep green, so that from a distance the plant reads almost like a small conifer until summer, when small bright yellow flowers scatter along the stems and settle the question of family.
Hypericum lloydii is one of the fine-textured St. John's Worts, a low, wiry evergreen shrub clothed in needle-like leaves so slender that the plant carries a heathery, almost coniferous look. Through the summer the stems light up with showy yellow flowers, each a shallow cup packed with stamens, held above foliage that stays green through the year.
Hypericum myrtifolium is the tidy, blue-leaved member of the group, an evergreen shrub whose small, leathery leaves clasp the stems in neat overlapping ranks and carry a soft glaucous, blue-green cast. In summer the bushy little frame fills with bright yellow flowers, each one a shallow cup brimming with stamens, the show carried on a plant that looks more like a miniature tree than a scrambling subshrub.
Hypericum prolificum lives up to the name, prolific, disappearing each summer under a heavy crop of bright yellow flowers, each three-quarters of an inch to an inch across and stuffed with a golden brush of stamens. The shrub is dense and rounded, with arching branches, narrow shiny leaves, and reddish, exfoliating bark that peels to show paler layers once the foliage thins.
Hypericum stans is the four-petaled member of the family, a small, upright shrub to about three feet with broad, clasping, blue-green leaves and shreddy, peeling bark. Through summer the stems carry bright yellow flowers an inch across, and where most St. John's Worts open five petals, these show four, set in a neat cross above a pair of large leafy sepals.
Ilex amelanchier is one of the surprises of the genus, a holly that drops the leaves in fall and carries none of the usual prickles. This rare native grows as a tall deciduous shrub or small tree, and the female plants, this one among them, hang dull, matte red berries on unusually long stems, a soft-toned, almost muted display quite unlike the glossy scarlet of a Christmas holly.
Ilex cassine, the dahoon holly, is an elegant evergreen native of the southern wetlands, and this is a fruiting female, the sex that carries the crop of small, glossy red berries. Unlike the fiercely spined American holly, dahoon holds narrow, smooth-edged, bright green leaves that are a pleasure to plant near a path, and in fall and winter the branches string themselves with scarlet fruit against that clean green. Grown as a large shrub or a small tree, dahoon is one of the most useful evergreen hollies for the South.
Ilex cassine, the Dahoon Holly, is one of the most useful evergreen hollies of the South, an upright shrub or small tree with bright green, oval, nearly spineless leaves. Female plants carry heavy crops of small, bright red berries, but this is a male selection, grown not for fruit but as the pollen partner that lets nearby female Dahoons set that red winter display.
Ilex coriacea, the large gallberry, is a tall evergreen holly of the Southern wetlands, close kin to the familiar inkberry but built on a bigger scale, with broader, leathery, dark green leaves and larger fruit. On female plants the berries ripen to a shining black, a quiet contrast to the glossy foliage through fall and winter.
Ilex glabra 'Nigra' is the inkberry chosen for good looks in every season, a compact, rounded evergreen holly with unusually rich, dark green leaves. Where the wild inkberry can bronze and dull through a hard winter, this selection was picked to hold a deeper, cleaner green, and the smooth, spineless foliage stays handsome on a tidy frame that runs lower and denser than the run of the species.
Ilex glabra, the inkberry or gallberry, is one of the finest native broadleaf evergreens of eastern North America, rooted in the sandy, acid soils of the coastal plain from Nova Scotia and New Jersey south through Florida and across the Gulf states. In wet pinelands, pocosins, and boggy edges this holly has long been a defining presence, and wherever the ground runs lean, sandy, and moist, inkberry settles in.
Ilex 'Sand Pond' is a Woodlanders introduction with a good story and better berries, a natural hybrid between two southeastern native hollies: the stately American holly, Ilex opaca, and the fine-textured myrtle-leaf holly, Ilex myrtifolia. The cross carries small, narrow, glossy evergreen leaves midway between the parents, on a plant that colors up each fall with an unusually heavy set of large red berries.
Ilex opaca, the American holly, is the classic evergreen holly of the eastern woods, a medium-size tree with tough, leathery, spine-edged leaves and, on female trees, the bright berries that have meant Christmas for generations. 'Fallaw' keeps the familiar form but changes the color of the fruit: where the wild tree ripens red, this selection hangs clear amber-yellow berries, an uncommon and cheerful contrast against the dark evergreen foliage.
Ilex opaca, the American holly, is the classic evergreen holly of eastern woods, a medium tree with tough, spine-edged, leathery leaves and the bright red berries that have meant Christmas for generations. 'Selected Red' is one of the good ones, a female clone Woodlanders propagated from a group of hollies planted many years ago in Aiken, South Carolina, chosen for very good foliage and an abundant crop of bright red fruit.
Ilex verticillata 'Jim Dandy' is a small shrub with an outsized job. Winterberry, the native deciduous holly, puts on one of the great shows in the winter garden, bare stems crowded with brilliant red fruit, but only female plants carry that fruit, and only when the right male blooms alongside them. 'Jim Dandy' is that male for the early-flowering winterberries, a dwarf pollinizer bred to bloom in step with them.
Ilex verticillata 'Maryland Beauty' is winterberry doing what winterberry does best, and a little more of it. This native deciduous holly loses the leaves in fall to reveal bare gray stems packed with fruit, and 'Maryland Beauty' was singled out from the northern strain for an especially heavy crop of bright red berries, a dense, glowing display that holds through the winter.
Ilex verticillata is the winterberry, the native deciduous holly grown not for evergreen leaves but for the astonishing display that comes after they fall: bare gray stems packed end to end with bright fruit, lit up across the dead of winter. 'Winter Gold' plays that trick in an unexpected color, trading the usual fire-engine red for warm gold blushed with soft orange-pink, a glowing, gentler note against snow.
