Clinopodium coccineum ‘Ohoopee Yellow’ wears a contradictory name, since this is a clear, bright yellow-flowered form of a mint shrub that usually blooms in scarlet. Yellow forms turn up rarely in wild populations, and the floras note them in passing as a curiosity. This one was caught and kept.
Clinopodium georgianum is a low, aromatic shrublet of the mint family, grown for strongly scented foliage and clouds of soft pinkish-lavender flowers from late summer into fall, peaking around September when much of the garden is winding down. Where the scarlet calamint is a hummingbird firework, Georgia savory is the quiet one: smaller flowers, softer color, and a season that arrives when the bees have run short of options. Crushed, the leaves smell frankly minty, with a sweet edge that one nurseryman has compared to expensive peppermint candy.
Large-flowered scarlet calamint is a small, wiry, semi-evergreen subshrub of the Florida sandhills, close kin to the better-known red basil, Clinopodium coccineum, and distinguished chiefly by the size of the flowers. Slender scarlet tubes, generously long, open along the stems from spring through summer and are built precisely for hummingbirds, which find them quickly and come back. The leaves are small, neat and aromatic, throwing a clean mint scent when brushed, and the whole plant stays open and airy rather than dense, better placed at the front of a bed than in the middle of it.
Clytostoma callistegioides is one of those vines that feels as though the plant wandered out of an old botanical expedition: vigorous, evergreen, and brimming with the sort of charm collectors once crossed oceans to find. A close relative of our native crossvine (Bignonia capreolata), this South American cousin shares the same athletic climbing spirit but dresses in glossier, more refined foliage and carries larger flowers.
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.
The conradinas are dense, aromatic, low shrubs of the mint family, dressed in small, usually needle-like green or gray leaves and hung with little pale purple flowers. Six or seven species grow wild in the southern United States, most of them in Florida on sand or very sandy soil, and the genus carries an unusual weight of rarity: four species are federally listed, C. brevifolia, C. etonia and C. glabra as endangered and C. verticillata as threatened, with two more carrying state protection in Florida. Conradina canescens is the exception and the common one, a somewhat variable plant of the Gulf Coast dunes of northwest Florida and adjacent Alabama and Mississippi.
Conradina canescens ‘Gray Mound’ is a silver-leaved selection of the false rosemary that grows wild on the deep, pine-fringed sands of the northern Gulf Coast, in Alabama, Mississippi, and the Florida panhandle, where the species holds the back of the primary dunes and runs inland into sand pine scrub. A member of the mint family, this aromatic shrub carries soft, needle-like foliage in a ghostly silver-gray, and from March into November, heaviest in spring, offers pale lavender to bluish two-lipped flowers spotted with dark purple on the lower lip, which native bees work steadily.
This small to medium shrub is in the mint family. It is a small shrub with gray-green narrow Rosemary-like aromatic leaves. The flowers are bluish and larger than other Conradinas. It is native on old dunes and deep sandy soil at scattered locations along the east coast of Florida. It needs a sunny site with well-drained sandy soil. Conradina grandiflora is a federally listed endangered species. NOT FOR SALE IN INTERSTATE COMMERCE
Some years ago we introduced two selections of Conradina collected on the Styx River in southern Alabama, called 'Low Gray' and 'Low Green', and we hope those clones survive in cultivation somewhere still. On a return visit to the Styx River site we gathered several more cuttings from distinctly low-growing plants. This conradina haunts a sandy woodland and cutover near the Styx River, and may well represent a new, as yet undescribed species; what appears to be the same plant turns up some miles east on Blackwater State Forest in northwest Florida. The Styx River plant differs clearly from the taller, more upright Conradina canescens of the open Gulf Coast.
Coreopsis integrifolia, the Chipola River coreopsis, is a rare southeastern native that saves its show for the end of the season. When most of the summer flowers have gone over, this tickseed lifts deep golden-yellow daisies, each centered with a dark maroon eye, on slender stems well above the foliage, bringing fresh color to the fall garden. A choice and uncommon perennial, known in the wild from only a handful of counties, the plant is as valuable to the gardener as it is to the pollinators working late.
Native to the open prairies and meadows of North America, Coreopsis lanceolata, the lanceleaf coreopsis, has long been admired for bright, golden-yellow blooms and an easy, hardy nature. This perennial wildflower has been a staple of North American landscapes for a very long time, growing across a wide range of climates and soils, from sandy coastal ground to the rich prairies of the Midwest.
Coreopsis verticillata, the threadleaf coreopsis, is a clump-forming native perennial dressed in fine, thread-like foliage and covered through the long weeks of summer in small, bright yellow, daisy-like flowers. Native to the open woods and clearings of the eastern United States, threadleaf coreopsis has become one of the most popular of all garden perennials, an easy, airy, long-blooming plant for the sunny border.
There is a version of the flowering dogwood almost nobody has met. Cornus florida 'Suwanee Squat' was found in Suwannee County, Florida, by Bob Simons, a forest ecologist who spent half a century protecting the wild hardwood country of north Florida. As a young man in the early 1970s he walked a mixed-hardwood hammock outside Gainesville, decided the place was worth saving, and talked ten landowners and the state into making it San Felasco Hammock; that became the pattern of his life. A man who knew that kind of forest the way most of us know our own street is exactly the sort to notice a dogwood doing something a dogwood is not supposed to do. Woodlanders introduced his low, sprawling oddity to cultivation, and the plant has stayed scarce ever since, the kind of tree you mostly hear about secondhand from someone who saw one and never got over it.
Cornus florida, the flowering dogwood, is the beloved understory tree of the eastern North American woods, widely planted for the great show of white spring bracts (the true flowers are the small green knot at the center), and, in selections like this one, pink. A deciduous woodland tree that grows in moist, well-drained soil in sun or high, dappled shade, the dogwood rewards careful planting: set the root flare high, and never plant too deep.
This elegant small tree carries a graceful, vase-shaped habit that rounds out with age. Blooming two to three weeks after Cornus florida, the kousa dogwood opens striking, pointed flower bracts in late spring to early summer, extending the dogwood season. The bracts surround clusters of tiny true flowers in a star-like display that sets this dogwood apart.
This Chinese dogwood is a spreading, small to medium deciduous tree with clean foliage and showy white-bracted flowers. Unlike the native American flowering dogwood, the bracts are sharply pointed. The tree flowers about a month later than Cornus florida, and is apparently immune or resistant to some of the disease problems that trouble Cornus florida in certain areas. A fine ornamental for an open, semi-shady lawn or border.
The American smoketree, Cotinus obovatus, is an uncommon small to medium native tree, kin to the familiar European smoketree but bolder in leaf and rarer in gardens. The common name comes from the fruiting stage, when the loose, fuzzy flower panicles blur the whole crown into a soft haze of smoke. The broad, oval, blue-green leaves are noticeably larger than those of the European Cotinus coggygria, and they close the year in a spectacular blaze of orange, yellow, and red-purple, some of the finest fall color of any native tree.
Crataegus harbisonii is a small, thorny, deciduous hawthorn with unusually large leaves for the genus, white spring flowers, and red fall fruit. Behind that modest description stands one of the rarest trees in North America: Harbison's hawthorn was perhaps once fairly common around central Tennessee, but is now all but extinct in the wild.
The parsley haw, Crataegus marshallii, is a distinctive and graceful small native tree, named for the shiny, deeply dissected, parsley-like leaves that set the whole genus apart at a glance. White flowers centered with rosy-red stamens open in spring, followed by bright red fruit that lingers into fall.
Crinum americanum is the swamp lily of the southeastern coastal plain, a bulb throwing broad strap-shaped leaves two to three feet long in a loose arching rosette, with scapes of about the same height carrying two to six flowers in a terminal umbel. The flowers are the whole event: glistening white, six narrow tepals recurved into a star five or six inches across, the long filaments tipped with dark anthers and often flushed rose-pink toward the base. Fragrance arrives after dark, sweet and carrying, which tells you plainly what does the pollinating. Bloom comes in waves from late spring into autumn, and nearly year-round in frost-free gardens.
