(Perfoliate Alexanders)
Be the first to rate this plant
Hardiness Zones: 1 2 3 4 5 6 7 8 9 10 11

This spring bloomer produces bright chartreuse floral domes atop bract-like, rounded leaves that are pierced by the flower's stem. This plant's form and color contrast well with spring bulbs. It grows 3 feet tall and 2 feet wide. Let it regenerate itself by self-sowing. It is a biennial or short-lived perennial that makes an excellent cut flower and produces worthy combinations with neighboring shades of maroons and blues. Grow it in large, mixed borders, naturalistic plantings, and open woodlands.

Sphaeralcea ambigua Sphaeralcea ambigua
(Desert mallow, Globe mallow)
Be the first to rate this plant
Hardiness Zones: 1 2 3 4 5 6 7 8 9 10 11

This shrubby, woolly perennial is native to the warmest, dry regions of the US and Mexico. Its large, rose-like salmon-colored flowers appear in loose clusters from spring to frost. It grows to 3 feet tall and almost as wide, and can bloom nearly year-round in warm regions.

Stachytarpheta urticifolia Stachytarpheta urticifolia
(Blue porter weed, Blue rat's tail, Nettleleaf velvetberry)
(1 user review)
Hardiness Zones: 1 2 3 4 5 6 7 8 9 10 11

This pest-free perennial blooms best during warm months. It is strange how these small blue flowers attract butterflies more than large-blooming, showy neighbors. Blue porter weed gradually reseeds nearby for a fresh batch of new plants. Mix with other species of Stachytarpheta for a variety of leaf shapes and colors ranging from purple to coral.

no image available Stipa arundinacea
(New Zealand wind grass, Pheasant's tail grass)
Be the first to rate this plant
Hardiness Zones: 1 2 3 4 5 6 7 8 9 10 11

This evergreen species makes a handsome specimen with narrow, arching foliage that is streaked orange in summer and becomes orange-brown in winter. Its fine, pendent flower inflorescences open purplish-green in midsummer and have a misty quality.

Stipa tenuissima Stipa tenuissima
(Mexican feather grass)
(5 user reviews)
Hardiness Zones: 1 2 3 4 5 6 7 8 9 10 11

No other grass exhibits quite the refinement of texture as this species. Its bright green foliage resembles delicate filaments that arise in elegant, vase-like clumps and spill outward like a soft fountain. All summer it bears a profusion of feathery panicles, which mature from foamy-green to blonde. It is native to the Americas.

Talinum paniculatum Talinum paniculatum
(Fameflower, Jewels of Opar)
(2 user reviews)
Hardiness Zones: 1 2 3 4 5 6 7 8 9 10 11

This tuberous-rooted tender perennial is related to portulaca, but has fleshy green leaves and delicate, wiry flower stalks. Stalks have a fine, see-through texture. Minute hot pink flowers are followed by carmine-colored seed pods that are showier than the flowers. The variety 'Kingwood Gold' has chartreuse foliage. Plants can grow to 3 feet tall and 2 feet wide.

Tetrapanax papyrifer Tetrapanax papyrifer
(Rice-paper plant)
(1 user review)
Hardiness Zones: 1 2 3 4 5 6 7 8 9 10 11

Large—to 20 inches across—almost rounded, lobed leaves colored a downy gray-tinged green contrast beautifully with almost any companion plant. This thicket-forming, sparsely branched, evergreen shrub, which behaves like an herbaceous perennial in Zones 6 and 7, produces thick, leafy shoots topped by white flowers borne on branching stems to 20 inches long in fall.

Thunbergia alata Thunbergia alata

(3 user reviews)
Hardiness Zones: 1 2 3 4 5 6 7 8 9 10 11

This tender perennial climber is evergreen in Zones 10 and warmer. Cheerful, 1.5-inch flowers in shades of orange and yellow cover this fast-growing vine. The blossoms have a simple form: 5 petals surrounding a brownish purple center. Where grown as an annual, plants can reach 8 feet; when grown as a perennial, 20 feet.

Trachelium caeruleum Trachelium caeruleum
(Blue throatwort)
Be the first to rate this plant
Hardiness Zones: 1 2 3 4 5 6 7 8 9 10 11

This species bears dome-shaped flower heads several inches across that are crowded with tiny, tubular amethyst or white flowers that look somewhat like the blooms of an allium. It has lance-shaped, toothed leaves in hues of cordovan purple or deep green brushed with plum highlights. It blooms over a long season. Though it is a perennial, blue throatwort performs wonderfully as an annual and blooms summer to fall. Plants grow to about 3 feet tall and wide.

Trachycarpus fortunei Trachycarpus fortunei
(Chinese windmill palm, Chusan palm)
Be the first to rate this plant
Hardiness Zones: 1 2 3 4 5 6 7 8 9 10 11

One of the hardiest palms, Chinese windmill palm has single stems with large, 4-foot-wide fans of sword-like leaves. It produces large plumes of yellow flowers in early summer; the flowers of female plants transform into bluish-black fruits. Chinese windmill palms may be shoot-hardy to Zone 6 if protected with 10 inches of mulch. With their rich fans and handsome habits, they make attractive specimens for formal outdoor spaces. These evergreen palms are native to the mountains and temperate regions of subtropical Asia. Plants can grow to 20 feet tall and 8 feet wide.

Tripsacum dactyloides Tripsacum dactyloides
(Eastern gamagrass)
Be the first to rate this plant
Hardiness Zones: 1 2 3 4 5 6 7 8 9 10 11

In early summer, slender stems are topped with flowers that produce a crop of jointed seeds. Clumps get large and die out in the center, so division is necessary. Autumn frosts turn the leaves attractive shades of red-bronze. -Scott Vogt, Native grasses, Fine Gardening issue #124

(Canary creeper)
Be the first to rate this plant
Hardiness Zones: 1 2 3 4 5 6 7 8 9 10 11

This annual or perennial climber grows vigorously, yet does not strangle its host. Its edible leaves are deeply divided like the fingers of a hand, and its bright yellow flowers are outrageously formed: The larger, upper petals are deeply fringed and look like tiny birds' wings; the smaller, lower petals are spurred. It blooms in summer and autumn and can climb up to 12 feet.

(Flame nasturtium, Scottish flame flower)
Be the first to rate this plant
Hardiness Zones: 1 2 3 4 5 6 7 8 9 10 11

This tender perennial climber has edible, hand-shaped leaves and crimson red flowers in summer and fall which are uniquely textured. Their softly squared petals are held apart from each other at the flower's mouth and the rear tapers to long spurs. The blooms yield blue fruits. Flame nasturtium climbs up to 10 feet.
