'Alison' is a sister selection to the famous 'Alice,' both drawn from the same native species by the same discerning eye. Hydrangea quercifolia, the oakleaf hydrangea, grows wild in the rich woods of a small Southeastern range centered on Alabama, where the naturalist William Bartram admired the shrub in the 1770s and where the oakleaf now serves as Alabama's official state wildflower. Of all the native shrubs of the region, few offer so much across so many seasons.
The oakleaf hydrangea is the great four-season native shrub of the American Southeast, a large deciduous plant with oak-like leaves, white summer panicles, and peeling cinnamon bark. Hydrangea quercifolia grows wild in the rich woods of a small range centered on Alabama, where the naturalist William Bartram admired the shrub in the 1770s, and where the oakleaf is now the official state wildflower. 'Harmony' is one of the boldest selections the species has produced.

Hydrangea quercifolia grows wild in the rich woods of a small range centered on Alabama, where the naturalist William Bartram admired the shrub in the 1770s, and where the oakleaf now serves as the state wildflower. 'Snowflake' is one of our favorites, and one of the most distinctive oakleafs ever selected.
Hydrangea serrata 'Woodlander' is a Woodlanders introduction with a story, a compact, small-leaved mountain hydrangea grown from seed collected at the Chollipo Arboretum in Korea and selected here for real garden charm. Daintier than the big bigleaf hydrangeas, this is a refined shrub of two to four feet, carrying flat lacecap flower heads of clear blue in acid soil, ringed with showy sterile florets around a center of tiny fertile ones. The serrated leaves take on a handsome purplish cast that deepens toward autumn.
Few native bulbs command a wet margin the way Hymenocallis liriosme does. From a basal fountain of arching, strap-shaped, glossy green leaves rise leafless scapes, each crowned with several large white flowers whose narrow segments splay outward like pale spider legs around a central membranous cup. The fragrance arrives at dusk, sweet and carrying, a signal to the night-flying moths that pollinate the blooms in late spring and early summer.
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 frondosum 'Sunburst' is the garden-refined face of a tough native shrub, a compact, rounded selection that mounds to about three feet and fills each summer with powderpuff golden flowers, the largest in the species at nearly two inches across, each a dense brush of stamens over broad yellow petals. The leaves are a cool blue-green, and as the season turns the older stems reveal red-brown, exfoliating bark, so the shrub keeps a quiet interest well past bloom.
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.
