Hardiness Zones: 1 2 3 4 5 6 7 8 9 10 11

A better-behaved cousin to the less-than-polite trumpet vine, cross vine is a colorful solution for a fence or arbor with afternoon shade. Although this east Texas native is slow to establish, ‘Tangerine Beauty’ sports brighter, showier flowers than other cultivars and will reward your patience with loads of orange blooms in both spring and fall. Flowers bloom on old wood, so prune this vine immediately only after blooms fade. -Leslie Finical Halleck, Fine Gardening #147 (October 2012), page 74

Hardiness Zones: 1 2 3 4 5 6 7 8 9 10 11

Butterfly bushes are carefree deciduous shrubs that are reliably fragrant and easy to grow. Butterflies swarm to their blooms all summer long. 'Lochinch' has extremely fragrant lilac-blue flowers with orange eyes. It is a cross between B. davidii and B. fallowiana. Its arching, mounded habit typically reaches 3 to 5 feet in one season, but can grow much taller in the deep South. The 8-  to 12-inch-long flower spikes begin in late summer and bloom until frost, starting a little later than the B. davidii cultivars.

(Butterfly bush, Summer lilac)
(1 user review)
Hardiness Zones: 1 2 3 4 5 6 7 8 9 10 11

This sun-lover comes in hues from pure white to deepest purple. From midsummer until frost, butterfly bush earns its name as hordes of winged beauties flit from flower to flower in search of nectar. The lanceolate leaves are 10 to 12 inches long and white or grayish underneath. The honey-scented flowers are deep purple and grow in spikes, from July to October.

A well-behaved perennial from the mint family (Lamiaceae), variegated calamint has pale-green, oval leaves with strong white marbling. It sends up a wealth of clear-pink tubular flowers that muster an army of bees, butterflies, and hummingbirds from mid- to late summer.

Lesser calamint produces fine, upright stems which are covered with small, shiny, dark green leaves, forming a little bush from 12 to 18 inches tall, and twice as wide. In late August, it produces a cloud of infinitesimal pale lavender flowers that continue blooming for up to six weeks. As the days become cooler, the color of the tiny, lipped blossoms deepens.

Each of this plant's stunning lance-shaped leaves is the softest gray-green, edged subtly with a cream-colored pinstripe. These luminous 5-foot-tall plants are crowned with spires of delicate pink flowers with just a blush of salmon.

Hardiness Zones: 1 2 3 4 5 6 7 8 9 10 11

A great canna to start with if you're convinced you hate them is 'Madame Paul Caseneuve', from 1902. The pearly-bronze leaves and almost purple stems of this 3- to 5-foot-tall antique beauty are the perfect foil for its elegant, sensual flowers of soft pink shading to peach and apricot.

Canna 'Sémaphore' Canna 'Sémaphore'

Hardiness Zones: 1 2 3 4 5 6 7 8 9 10 11

Growing to 6 or 7 feet, 'Sémaphore' features slender, dark-bronze leaves topped by spikes of narrow-petaled flowers of an unusual glowing color that's not quite yellow and not quite orange; perhaps flickering tongues of flame would be the best description. It is a Victorian classic from 1895.

Cannas bear broad, smooth paddle-like leaves reminiscent of banana plants. The oversize leaves make it easy to create dramatic combinations with other, more finely textured plants. Each stout, fleshy stem is topped with attractive spires of brightly colored flowers. Cultivars vary widely in height, foliage, and bloom.

Two-foot-tall, stiff, orange-brown blades curve at the end like a shepherd’s staff. Burnished red-bronze foliage, which fades to flax at the tips, gives off a warm glow when backlit by the sun.

These plants can take worst of the a hot summer (heat, lack of water, and humidity) and still manage to perform well. They generally live four to five years before they need replacing, but during that time, they offer dependable foliage and pretty blue flowers from mid- to late summer. Blue-mist shrubs form low-growing, finely-textured mounds and are deer-resistant.

Bachelor's buttons bear charming and prolific flowers in hues of blue, pink, lavender, white, and maroon. Those with a true blue color are especially welcome in the garden as that color is rare in nature.

Ceratotheca triloba Ceratotheca triloba
(South African foxglove)
Be the first to rate this plant

A rare and graceful beauty, this plant is not a true foxglove, but its flowers are similarly shaped and hang in clusters. They come in shades of white and pink with pale violet stripes highlighting the inner throats. This plant’s soft coloring brings the delicacy typical of spring-blooming plants into the summer garden. The gray-green foliage has a distinctly nutty fragrance and is deer resistant. As a large-scale plant, South African foxglove holds its own when planted among shrubs and is best complemented by plants with deep purple foliage. It also makes a good cutting flower.

Cerinthe major ‘Purpurascens’ Cerinthe major ‘Purpurascens’
(Blue shrimp plant)
(1 user review)

Though subtly colored, Cerinthe major ‘Purpurascens’ draws comment wherever it inserts itself. The steely purple bracts and leathery gray foliage of this annual seem extraterrestrial poking up among more conventional herbaceous plants. It is an annual from the Mediterranean region with leaves like a eucalyptus and flowers like a purple euphorbia. This plant produces large black seeds that drop to the ground in late summer and germinate in fall to start the cycle all over again if growing conditions are right.

A hardy perennial, chamomile has aromatic, threadlike leaves that fill the air with a pleasing apple-pineapple scent. White, daisylike blooms appear in summer.

Cosmos are branching annuals with ferny foliage and pink, crimson, or white flowers that work well in the back of a border. Although introduced in 1799, cosmos did not beome popular for the garden or as the subject of breeding efforts until the early 1900s. The rest is now history. The variety 'Sensation' won the All-American Selection Award of Merit in 1936 for its clear colors of pink and white, on early-blooming, 3- to 4-foot-tall plants. 'Purity' is the glistening white form of cosmos in the 'Sensation' series. 'Sea Shells' has quilled florets. The Sonata Series cultivars are dwarf plants only growing to about a foot or two tall.

Arising in midsummer from neat clumps of fine-toothed foliage, a mass of soft yellow open bells, speckled brown inside, blooms along one side of a 3-foot-tall stem. Usually described as a perennial, it is more accurate to call it a biennial or short-lived perennial. If the flowering stalk is cut down after blooms have faded, it may rebloom in the fall. When a few flower stalks are left, the plant self-seeds.

'Indigo Spires' sage is a vigorous hybrid prized for its 12- to 15-inch-long, twisting spikes of dark violet flowers. It is a non-stop bloomer from early summer through fall. Blooming can be further encouraged by pinching stem tips early in the growing season and deadheading the spikes once they fade. 'Indigo Spires' quickly grows to 4 feet high, and can be grown as an annual where not hardy.
