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.
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 '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 'Winter Red' is the winterberry other winterberries are measured against. A large, rounded female of the southern strain, 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.
Yaupon is the small-leaved evergreen holly of the southeastern coastal plain, native from Virginia to Texas and a member of the holly family, Aquifoliaceae. Adaptable almost to a fault, salt tolerant, drought tolerant, and content in sun or shade, the species takes shearing as neatly as boxwood and has served Southern gardens for generations as hedge, screen, and clipped structure. 'Hoskins Shadow' is a standout among the named forms: a dense, fast-growing shrub or small tree, 15 to 20 feet in time, chosen for unusually large, dark green foliage and, above all, for cold hardiness well beyond the ordinary yaupon.

Yaupon holly is a small-leaved evergreen shrub or small tree of the southeastern United States, native from coastal Virginia south to Texas. Adaptable to a fault, salt tolerant, drought tolerant, and willing in sun or shade, yaupon takes shearing as gracefully as any boxwood, which has made the species a Southern mainstay for hedges, topiary, and clipped evergreen structure. The tiny white spring flowers are easy to miss, but the bees do not miss them, and on female plants they give way to a heavy crop of small, translucent berries that hang on well into winter.

The anise trees, genus Illicium, are aromatic broadleaf evergreens of the star-anise family, Schisandraceae, named from the Latin illicium, an allurement, for the scent of their leaves. Illicium floridanum, the Florida anise, is the Southeast's own contribution, a shade-loving evergreen native along shaded streambanks and seepage slopes from the Florida panhandle to Louisiana. 'Halley's Comet' is one of the best selections, a vigorous but compact form with especially dark foliage and a heavy show of velvety, star-shaped flowers in deep wine-red.
Among the wild irises of North America, Iris fulva is the one that broke the color rules. Where the family runs to blues, purples, and yellows, the copper iris opens in warm coppery red to burnt orange, a shade no other native iris offers, carried on slender stems in late spring and early summer with a soft, slightly drooping poise. The Latin fulva, meaning tawny or reddish-brown, records that unusual color, and the common names, copper iris and red iris, say the same thing more plainly.
Few native perennials burn as bright as Lobelia cardinalis, the cardinal flower, whose late-summer spikes of pure, velvety scarlet stop traffic in any garden. The species ranges across much of North America along stream banks, wet meadows, and ditches, and takes the common name from the vivid red of a cardinal's robes. From a low rosette of broad green leaves rises a stiff, unbranched stem hung with tubular flowers built, as luck would have it, precisely to the reach of a hummingbird's bill.
Lonicera sempervirens 'Leo' is the coral honeysuckle at its free-flowering best, a selection of the native red honeysuckle that covers itself in bright red, yellow-throated trumpets over an unusually long season. The tubular flowers pour nectar for ruby-throated hummingbirds, which find the vine as irresistible as gardeners do, and the blue-green leaves, some fused right around the stem, make a cool foil for all that heat.
Malvaviscus arboreus, affectionately known as Turk's cap, has charmed gardeners for generations with vibrant, coiled blooms that never quite open, each red flower staying furled like a little turban, which is exactly how the plant earned its name. A close cousin of the hibiscus in the mallow family, Malvaceae, this tough, subtropical shrub carries a story as rich as the scarlet flowers, and two more common names besides: wax mallow and sleeping hibiscus.
'Jacob Cline' is the beebalm to beat for sheer red, a native perennial that throws big, deep-crimson flowerheads on tall stems through the heart of summer. The whorled, tubular blooms sit atop four to five feet of square, mint-family stems, and they pull in hummingbirds, bees, and butterflies with a persistence few perennials match; in one major trial 'Jacob Cline' was the single best beebalm for hummingbirds.
Oxydendrum arboreum, the sourwood, is one of the loveliest and most distinctive trees of the Eastern American woods, and among the very last to flower each year. The name tells the story twice over: Oxydendrum joins the Greek oxys, sour or sharp, and dendron, tree, while the common name echoes the same tang, for the leaves, twigs, and bark all taste sourly of oxalic acid when chewed. A member of the heath family alongside azaleas, rhododendrons, and blueberries, sourwood stands alone as the sole species in the genus, native to well-drained, acid woodland soils from southern Pennsylvania to the Florida panhandle and west toward Louisiana, most abundant in the lower Appalachians.

Turkey oak earns the name from the leaf, three-lobed and clawed and splayed exactly like the track a wild turkey leaves in sand, which is fitting, because sand is where these trees live. Quercus laevis is the signature oak of the deep sandhills, the droughty white-sand ridges of the longleaf country from the Carolinas to the Gulf, ground so poor and so hot that most trees simply decline the invitation.
Nuttall oak is named for Thomas Nuttall, the restless English-American naturalist who botanized the young United States more thoroughly than almost anyone of his generation. Long known as Quercus nuttallii, the tree now carries the name Quercus texana in most botanical usage, a change that has caused no end of confusion, since the name once belonged to a different oak. Whatever the label, this is a large deciduous red oak of the Southern bottomlands, at home in the floodplain forests of the Gulf Coast and the Mississippi valley.
'Reagan' is a richly colored selection of the Florida azalea, Rhododendron austrinum, chosen in the wild in Florida near the Apalachicola River, the great blackwater river whose ravines shelter some of the Southeast's rarest plants. Where the typical Florida azalea runs to clear gold and orange, this form pairs yellow petals with deep reddish-pink buds and flower tubes, so that from a distance the whole shrub takes on a warm, red-flushed glow uncommon in the species.
Flame azalea is the showiest of all the native azaleas, and the one that stops hikers in their tracks on the Appalachian balds each June. The large, funnel-shaped flowers open in a fiery range that runs from clear yellow through gold and apricot to blazing orange and scarlet, carried in loose trusses just as the new leaves expand. For all that color the flowers are, unusually, without scent, but nothing about a flame azalea in full bloom feels the lack.
'Dawn at the River' is a fine selection of the native flame azalea, Rhododendron calendulaceum, one of the most spectacular of all the wild deciduous azaleas of the eastern mountains. The species blankets woodland slopes and high mountain balds through the southern Appalachians, from Pennsylvania to Georgia, where the famous flame-colored display draws pilgrims to places like Gregory Bald each June. The species name calendulaceum means resembling Calendula, the marigold, a nod to the vivid orange of the flowers, while the common name flame azalea catches both that fire and the way the upright buds stand like candle flames.
The Oconee azalea is the flame azalea of the lowlands, and for a Southern gardener that difference matters. Where the mountain flame azalea pines for cool Appalachian summers, this Piedmont cousin was born to the heat, thriving in the clay hills and stream bluffs of middle Georgia and South Carolina and taking the humidity of the Deep South in stride. The reward is the same fire in the flower: bright orange to orange-red trusses, sometimes shading to salmon or gold, opening in mid-spring.
Fragrant sumac is a versatile deciduous shrub native across much of the eastern and central United States, where the plant threads scattered woodlands, rocky slopes, and open banks. The trifoliate leaves, often mistaken at a glance for poison oak, are entirely harmless, and a crushed leaf releases the clean, lemony-resinous scent that gives the plant every one of the common names, from fragrant sumac to skunkbush, depending on the nose. The genus name Rhus is the old Greek and Latin word for the sumacs, and the epithet aromatica names the scent directly.

Littleleaf sumac is a big, bushy deciduous shrub of west Texas, the Southwest, and adjoining Mexico, built for heat, sun, and drought. The compound leaves are made up of tiny leaflets that give a fine, almost feathery texture, and they turn rose to purple in fall, an unusual and lovely tone among the sumacs. Tough and dryland-hardy, the plant is well worth trying in the South and any hot, well-drained garden.
