The shrubs that furnish a garden. Small and medium shrubs are the versatile, human-scaled woody plants that fill borders, edge paths, and knit the taller structure to the ground, the layer most gardens rely on most.
'All Summer Beauty' answers the oldest complaint about mophead hydrangeas: that a single hard freeze or an eager pruner can wipe out a whole season of bloom. Where classic bigleaf hydrangeas flower only on old wood, this compact selection, three to four feet high and wide, blooms on both old and new growth, so the rounded heads keep coming through the season and return even after a winter that kills the older stems. The name is a promise the plant generally keeps.
'Mariesii' is a piece of hydrangea history still in commerce. In the late 1870s the English plant hunter Charles Maries, collecting in Japan for the famous Veitch nursery, sent home the first lacecap hydrangea to reach the West, at a time when European gardeners knew only the round mopheads. That introduction, named 'Mariesii' in his honor, opened Western eyes to the wild, flat-topped grace of the lacecap and became the parent of a whole line of classic cultivars, among them 'Mariesii Grandiflora', 'Mariesii Lilacina', and the blue 'Mariesii Perfecta'.
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.
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 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 nudiflorum is the early riser among the St. John's Worts, a slender, upright shrub that opens golden flowers as early as May, often a full month ahead of relatives. The blooms carry the many-stamened brush typical of the clan, set against broad, light green, oval leaves that give the plant a softer, leafier look than the needle-leaved species.
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 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 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.
Ilex verticillata ‘Winter Red’ is the winterberry other winterberries are measured against. A large, rounded female, six to ten feet high and wide, this native holly drops the summer leaves to reveal bare stems packed with profuse, glossy red berries, and where lesser clones fade, ‘Winter Red’ holds the color clean and bright deep into the season, right through the coldest months.
Ilex 'Raritan Chief' is a male winterberry with a long working day. A compact hybrid of the native winterberry, Ilex verticillata, and the Japanese winterberry, Ilex serrata, this deciduous holly was bred as a pollinizer rather than a show plant, and a long bloom season makes 'Raritan Chief' one of the most flexible pollinizers in the group.
Ted Stephens of Nurseries Caroliniana calls this one of his top ten favorite plants, and the reason is bloom. Indigofera amblyantha, the pink indigo, is a fast, airy, deciduous shrub from the streambanks of central China, a nitrogen-fixing legume in the vast genus Indigofera, and one of the longest-flowering hardy shrubs a Southern garden can grow.
Indigofera heterantha, the Himalayan indigo, is a graceful deciduous shrub from the mountains of the western Himalaya, a nitrogen-fixing legume grown for a long summer-into-fall run of rosy-purple pea flowers over ferny foliage. Michael Dirr, in his Manual of Woody Landscape Plants, notes that the species has performed admirably in his Georgia trials, and the plant has earned a quiet following among Southern gardeners for toughness and length of bloom.
