Turn up the heat. The blazing beauties are the plants that bring fire to the garden, the hot reds, blazing oranges, and molten yellows that carry the sunniest, most exuberant color a border can hold.
Pine-leaved bottlebrush earns the name honestly: the foliage is fine, stiff, and needle-like, closer to a young pine than to the broad leaves of most bottlebrushes, and the whole shrub stands upright and a little spare, which is part of the charm. Native to southeastern Australia, this species is uncommon in cultivation in the southern United States, so growing one is a small act of plant collecting.
An exceptional cold-hardy bottlebrush, Callistemon rigidus 'Clemson' is a compact to medium evergreen shrub hung with brilliant red, brush-like flowers that bloom heavily in late spring and often rebloom through summer. Native to Australia, this selection defies expectations for the genus by thriving outdoors in upstate South Carolina, where winters are usually too cold for bottlebrushes.
Clinopodium coccineum is a small, aromatic, semi-evergreen subshrub of the mint family, native to the deep, well-drained sands of the southeastern coastal plain, from Mississippi and Georgia down into Florida. The loose, open frame and small, spicy-scented leaves would earn a quiet place on their own, but the flowers are the event: showy scarlet tubes carried over a long summer season, held out like little trumpets that hummingbirds cannot resist.
Colquhounia coccinea is a showy, soft-wooded shrub of the mint family, clothed in medium-sized leaves that are downy and pleasantly rough to the touch. Through late summer and fall come dense terminal spikes of orange-scarlet, yellow-throated flowers, a hot late-season color that hummingbirds and pollinating insects work eagerly. Plant in a sunny, well-drained site with good soil, where the arching stems can be trained against a warm wall.
Crocosmia 'Lucifer' is a vigorous, corm-forming perennial and one of the best summer plants for the southern garden, multiplying steadily in good, moist, neutral to acid soil in sun or light shade. Tall, arching spikes of brilliant red-orange, flame-colored flowers rise over the clump through early to midsummer, held above fans of pleated, sword-like green leaves.
Once thought lost to time and development, Cyrilla arida, known as Scrub Titi, is a botanical rarity with a story as striking as the summer bloom. The famed botanist J.K. Small first described this shrub in the early twentieth century from the desert-like scrub of central Florida. For decades the identity of Scrub Titi was debated and any wild presence uncertain, until a dedicated search led to rediscovery by Kenneth Wurdack and the Woodlanders team in Highlands County, Florida. That tiny remnant population may now be gone, and Cyrilla arida may no longer exist in the wild, which makes every plant in cultivation all the more precious.
Dicliptera suberecta is a member of the acanthus family, Acanthaceae, and hails from the grasslands of Uruguay and Argentina, a heritage that shows in a love of heat, sun, and lean soil. Gardeners know the plant by two names that between them tell the whole story: Uruguayan firecracker plant, for the volley of tubular blooms, and hummingbird plant, for the traffic those blooms draw.
A relic of the old Southern wilds, Erythrina herbacea, the coral bean, is a plant that commands attention, graceful yet defiant, wild yet refined. A legume native across the coastal Southeast, the coral bean shifts habit with the winter: in frost-free zones the plant grows as a woody shrub, branching boldly above the ground, while farther north the top dies down with the first hard freeze, only to rise again from a thick, gnarled rootstock when the heat returns, an emblem of Southern resilience.
The native fothergillas were choice but scarcely available garden shrubs when Woodlanders first began to offer them back in 1980. This one, a hybrid of Fothergilla gardenii and F. major, was found by Dr. Michael Dirr at the Mt. Airy Arboretum in Cincinnati, Ohio, and has since become the most widely grown fothergilla of all, and deservedly so.
Grevillea 'Canberra Gem' is a bold and unusual Australian evergreen, a hybrid of Grevillea juniperina and Grevillea rosmarinifolia that brings fine texture, vivid color, and a touch of the exotic to an adventurous garden. The narrow, needle-like foliage is often mistaken for a conifer, until late winter, when the shrub reveals a true identity in a profusion of rose-red, spider-like flowers that spill from the branches and catch the eye clear across the garden.
Grevillea rosmarinifolia is a fine-textured Australian evergreen, a rounded to semi-prostrate shrub whose narrow, deep green leaves look uncannily like rosemary, giving the plant both the species name and a handsome, needled presence the year round. The likeness is only skin-deep, for this is a member of the protea family, Proteaceae, worlds away from any herb.
Redwing is grown less for the flowers than for what follows them. Through the warm months this fast, twining, semi-woody climber carries loose clusters of small clear-yellow flowers along the stems, pretty enough in passing, but the real event comes after, when each pollinated bloom ripens into a bright red winged fruit, a samara built exactly like the spinning key of a maple. In quantity the red keys smother the vine and glow against the small, neat foliage, an unexpected and long-lasting display that few visitors can name.
Hibiscus coccineus, the scarlet rose mallow or Texas star hibiscus, is a tall, dramatic perennial native to the wetlands and swamps of the southern United States. Rising on strong, upright stems to six or ten feet, the plant lifts great scarlet stars above the summer garden, an American native that looks every bit as exotic as any tropical hibiscus and proves far tougher.
Hibiscus mutabilis has been grown in Southern gardens for so long that many people assume the shrub is a native, though the species traces to southern China, where gardeners prized the flowers centuries before the plant traveled west. The species name mutabilis, meaning changeable, describes the wild trick of the ordinary Confederate Rose, whose blooms open white in the morning and deepen to pink and then rose-red by evening. 'Rubrum' skips the performance and commits: the single flowers arrive already a saturated rose-red and hold that one deep tone through the day rather than shifting. For gardeners who love the late-season drama of the Confederate Rose but want a single, unwavering color, 'Rubrum' is the selection to plant.
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 latifolia is the holly that stops people in their tracks, an evergreen tree carrying the largest leaves of any holly, glossy, leathery, and up to eight inches long, more like a magnolia or a loquat than the little prickly leaves most gardeners expect. The edges are finely serrated rather than spined, the surface a deep polished green, and on female trees such as 'Alva' tight clusters of small red berries stud the branches through fall and winter.
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 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 spinigera is a holly with a deep past, a rare evergreen from the Hyrcanian forests that ring the southern Caspian Sea in northern Iran. Small, glossy, dark green leaves edged with fine spines clothe a dense small tree or large shrub, and on female plants such as this one bright red berries glow against the foliage through fall and into winter, the classic holly effect on an uncommonly ancient plant.
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.
