Jasminum officinale var. grandiflorum, the Spanish or Royal jasmine, is the large-flowered, intensely fragrant jasmine of perfume and tradition, a semi-evergreen twining vine that opens clusters of pure white, star-shaped flowers whose scent is among the most prized in the plant world. Larger-flowered and more tender than the common poet's jasmine, this is the plant behind jasmine absolute, the costly essence at the heart of classic perfumery.

Jasminum x stephanense, the Stephan jasmine, is the rare pink-flowered hybrid of the group, a cross between the red jasmine, Jasminum beesianum, and the poet's jasmine, Jasminum officinale. The vigorous, semi-evergreen scrambling vine carries small, soft pink, fragrant flowers over slender stems clothed in fine pinnate leaves, combining the pink of one parent with the hardiness and perfume of the other.
By late summer, when many shrubs have said their piece, Lespedeza thunbergii 'Spring Grove' is only clearing its throat. The many woody, arching stems bend into a green fountain through the season, then bow lower still under a long, generous fall of rose-purple pea flowers carried in racemes six to eight inches long. 'Spring Grove' is a newer selection said to hold darker purple flowers and a tidier, better habit than the old standard 'Gibraltar', and the photographs here come courtesy of the JC Raulston Arboretum.
Spicebush is the shrub that tells you the ground is good. Early land surveyors in the eastern states used Lindera benzoin as an indicator of rich agricultural soil, and the rule holds in the garden: where spicebush thrives, most things will. The plant is a common understory shrub of moist, rich woods from Ontario to Florida and west to Texas, growing six to twelve feet in a loose rounded mass, often colonial from root sprouts, and every part smells of citrus and pepper when bruised.
In the dead of winter, when the garden asks for little and gives less, Lonicera × purpusii answers with perfume. This winter honeysuckle is a hybrid of two Chinese species, Lonicera fragrantissima and Lonicera standishii, and carries the best of both: small, creamy-white, tubular flowers that open along the bare stems from late winter into early spring, throwing a clean, lemon-sweet fragrance that carries yards on a mild day.
Magnolia virginiana, the sweetbay magnolia, has long been a tree of distinction in the American landscape, ranging from the cool wetlands of Massachusetts to the Gulf Coast. Across that span the species wears two very different guises. In the northern states the sweetbay is a smaller, often shrubby tree that drops its leaves in winter; in the Deep South the species reaches fullest expression as Magnolia virginiana var. australis, the evergreen southern sweetbay, a large and enduring tree of great grace.
This is the uncommon pink-flowered Turk's cap, a soft-toned form of the familiar scarlet Malvaviscus arboreus, a subtropical relative of the hibiscus in the mallow family, Malvaceae. The flowers carry the same charming quirk as the red kind: two to three inches long, they never open flat like a hibiscus but stay furled in a little turban, glowing here in clear pink rather than red.
Malvaviscus drummondii is the small Turk's cap, the wild, native cousin of the larger Mexican wax mallow and, for many Southern gardeners, the better plant of the two. A relative of the hibiscus in the mallow family, Malvaceae, this shrubby perennial is native to Texas, the Gulf Coast states, and on south, and grows wild in the dappled shade of woodland edges and stream banks where few other bright flowers will bloom.
'Pam Puryear' is the soft-pink small Turk's cap, a lovely departure from the usual fire-engine red of this tough native mallow. The furled, never-quite-open flowers keep the charming Turk's cap form, less than two inches long and produced without pause through the hot months, but here they glow a gentle shell pink that reads cool and quiet in the summer border.
Myrcianthes fragrans is a member of the myrtle family native to the hammocks and coastal scrub of Florida and the Caribbean, the same botanical neighborhood as guava and allspice, which says something about the family character and the quality of the fragrance involved. Crush a leaf and the scent is immediate and specific: nutmeg with a citrus edge, clean and resinous in a way that makes the plant worth encountering even out of flower. The tiny, deep green leaves hold the aromatic oils responsible, and keep that quality year-round.
Black gum is one of the longest-lived hardwoods in eastern North America; individual trees have been aged past six hundred and fifty years, standing quietly in swamp margins and rocky uplands while everything human around them came and went. The names alone are a small history lesson. Nyssa was a water nymph of Greek myth, sylvatica means of the woods, so the botanical name reads as water nymph of the forest; tupelo comes from the Creek ito and opilwa, tree and swamp; and the old northern name pepperidge is the one a Connecticut baker borrowed for her farm and her bread company. Curiously, no part of the tree is gummy at all. What black gum does own is the autumn. They are among the first trees to turn and among the fiercest, the glossy summer leaves igniting into scarlet, orange, and deep wine-purple weeks before the rest of the woods has given the season a thought, an early flare that signals birds to the ripening blue fruit. The wood is so cross-grained it is nearly impossible to split, which sent it into tool handles, chopping bowls, and, where trunks went hollow with age, into bee gums, the log hives that made gum a synonym for beehive across Appalachia. Black gum is notoriously hard to move at any size, which is exactly why you so rarely see a big one for sale, and exactly why you should start one small, now, and let them outlive you.

The purple firespike answers a quiet complaint of the warm-climate gardener, that the tropical border runs to reds and hot corals and forgets the cooler end of the spectrum. Odontonema callistachyum carries erect spikes of tubular, lavender-to-amethyst flowers at the tip of nearly every branch, each spike lengthening to almost a foot as the buds open in succession from fall into spring. The genus name joins the Greek odous, a tooth, with nema, a thread, for the small toothed filaments within the bloom, while the epithet callistachyum means, simply and accurately, beautiful spike. The leaves are broad, glossy, and faintly fleshy, a lacquered dark green that holds the plant together as a handsome mound even between flushes.
A true olive for the shade, Olea yunnanensis is the sort of plant that rewards the gardener who reads labels twice. The genus is the olive genus, kin to the ancient Mediterranean fruit tree and to the sweet olives and privets of the same family, yet this species hails from the mountains of Yunnan in southwestern China rather than the sun-baked hills of the Old World. The narrow, leathery, dark green leaves carry an unmistakable Osmanthus cast, glossy above and paler beneath, and build into a dense, rounded evergreen canopy that holds the year.
Penstemon digitalis is one of the most adaptable of the native beardtongues, a clump-forming perennial of moist meadows, prairies, and open woods across the eastern and central United States. 'Husker Red', selected at the University of Nebraska and named Perennial Plant of the Year in 1996, keeps all the toughness of the wild species but wears it in deep wine-red: a basal rosette of glossy maroon foliage that holds color from spring through fall.
Phlox carolina 'Kim' is among the best of the Carolina phloxes, a selection found by the plantswoman Jan Midgley in Alabama and grown ever since for good health and honest flower power. From a low, tidy clump of narrow, almost lime-green leaves rise sturdy stems eighteen to twenty-four inches tall, each carrying an open, airy cluster of pale to bright pink flowers, five petals apiece, hovering just above the foliage from late spring into early summer. Where the border phloxes so often finish the season spotted and tired, 'Kim' holds clean, fresh foliage from spring straight through fall.
Physostegia correllii, Correll's obedient plant, is a rare and handsome member of the mint family, a robust, upright, somewhat succulent perennial rising from thick, spreading rhizomes. Among the false dragonheads the species stands out for unusually dark, glossy green leaves and cool purplish-pink flowers streaked and spotted with darker purple, an inch long and packed into dense terminal spikes.
In Japan they call the shrub tobira, short for tobira no ki, the door tree, because the cut branches were hung in the doorway at Setsubun to turn back demons at the threshold of spring. The broken wood smells rank, which was rather the point: bad spirits, like most of us, would rather not walk through a bad smell. The genus name is kinder and more exact, pitta and sporos, pitch and seed, for the resin that coats the black seeds and glues them to whatever bird carries them off.
Podranea ricasoliana, the pink trumpet vine or Port St. John's creeper, is a fast-growing evergreen climber from the warm regions of South Africa, a member of the trumpet-creeper family, Bignoniaceae, prized for showy, trumpet-shaped flowers.
Polygala x dalmaisiana, the sweet pea shrub, is a fast-growing evergreen hybrid of two South African species (P. oppositifolia and P. myrtifolia), grown for a nearly year-round show of orchid-like flowers on an open, informal frame.
The English laurel is a large broadleaf evergreen shrub grown for bold, glossy foliage, spires of small white flowers, and, at times, small cherry-like red-to-black fruits. The species is variable, with a number of cultivated forms, and the plant is native to eastern Europe and Asia Minor.
