This is a vigorous grower. Its beautiful dark fruits, which arrive after the flowers, bring an abundance of birds.

Asarina scandens Asarina scandens
(Figwort, Creeping snapdragon)
(2 user reviews)

A half-hardy perennial, this sophisticated climber grows to 8 feet tall. It has a profuse show of 1.5-inch indigo, violet, pink, or white flowers. It's great for the cold greenhouse or conservatory, and will often bloom until the end of the year unless there is a hard frost.

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

Tatarian aster is an impressive, stately perennial with a flowering height of 3 to 6 feet. It can look you in the eye yet require no staking. More important, this aster flowers longer than any other garden aster, beginning in late September and early October and continuing into November. The 1-inch-wide, light lavender flowers are a magnet for local and migrating monarch butterflies. This plant tolerates many soil types, can form large colonies in a few years, and is easily divided.

Clematis crispa Clematis crispa
(Marsh clematis, Blue jasmine, Curly clematis)
Be the first to rate this plant
Hardiness Zones: 1 2 3 4 5 6 7 8 9 10 11

A deciduous climber native to the southeastern United States, Clematis crispa bears lavender-blue, bell-shaped flowers with curly edges in summer. Its blooms are not profuse, but their elegant shape makes this plant a good choice for trellises, growing through shrubs, or planting in damp areas. The flowers are slightly fragrant and are followed by attractive seedheads. It also makes an unusual cut flower.

Crambe cordifolia Crambe cordifolia
(Colewort)
(1 user review)
Hardiness Zones: 1 2 3 4 5 6 7 8 9 10 11

This species is notable in stature, forming a giant mound and producing a profusion of airy white flowers on tall stems in late spring to midsummer and then dying down in midsummer to late summer. Colewort can reach 8 feet high and about half as wide. Grow in a large border or open woodland.

Eremurus robustus Eremurus robustus
(Foxtail lily, Desert candle)
(1 user review)
Hardiness Zones: 1 2 3 4 5 6 7 8 9 10 11

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

This is the granddaddy of big-leaved perennials. No other plant can so thoroughly alter the scale of a garden while calling such attention to itself.

Helianthus angustifolius Helianthus angustifolius
(Swamp sunflower)
Be the first to rate this plant
Hardiness Zones: 1 2 3 4 5 6 7 8 9 10 11

A profusion of golden yellow flowers appears for two to three weeks starting in early autumn. Daisy-like flowerheads are 3 inches across with 15 to 20 yellow ray florets radiating from a flat-topped purple or dark brown cone. The entire plant looks like a giant flame, drawing the attention of gardeners and many species of butterflies, bees, and other nectar feeders.

Helianthus grosse-serratus Helianthus grosse-serratus
(Sawtooth sunflower)
(1 user review)
Hardiness Zones: 1 2 3 4 5 6 7 8 9 10 11

Sawtooth sunflower's abundant yellow daisy flowers bloom from late summer well into fall. The dark green, narrow leaves have a leathery gloss. A well-behaved plant, sawtooth sunflower forms a thick, slowly expanding clump. It can reach 10 feet and taller, depending on conditions.

Hibiscus moscheutos and cvs. Hibiscus moscheutos and cvs.
(Common rose mallow, Swamp rose mallow)
(2 user reviews)
Hardiness Zones: 1 2 3 4 5 6 7 8 9 10 11

This bold, strong-growing, woody-based perennial hibiscus has erect stems reaching up to 8 feet tall with 8-inch-wide, funnel-shaped flowers with spreading petals in shades of pink, white, or crimson.

Silphium laciniatum Silphium laciniatum
(Compass plant, Pilot plant, Polar plant)
(1 user review)
Hardiness Zones: 1 2 3 4 5 6 7 8 9 10 11

This tall, sturdy prairie plant makes an imposing statement in the garden with its large, deeply cut leaves and yellow sunflower-like flowers that face east and bloom in late summer and early fall. The leaves of the compass plant can grow up to 18 inches long and are deeply incised with a shape that looks like something from a painting by Matisse. They align themselves on a north-south axis to conserve moisture by avoiding the midday sun. This plant requires a few years to enlarge and flower, but once its deep roots are anchored, it will live for many years.

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

A coarse but bold perennial giant for the back of the border with yellow, daisy-like flowers in summer. Cups form where the toothed leaves meet the thick stems; birds are said to drink from the water held in the cups. Tough prairie natives that will self-sow, these plants need lots of sun and lots of room—a single plant can reach 7 or 8 feet tall and 6 feet across.

Thalictrum rochebruneanum 'Lavender Mist' Thalictrum rochebruneanum 'Lavender Mist'
(Meadow rue)

This hauntingly beautiful specimen has blue-green foliage along matte, purple-green, willowy stems. At 5 or more feet in height, it has a dramatic yet delicate garden presence. Its sprays of nodding lilac flowers have pale yellow stamens. Plant at the back of a border; it may require staking.

(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.
