Growing to less than 2 feet tall and wide, 'Purple Dome' covers itself with semi-double, deep purple, daisy-like flowers from late summer to midfall. In addition to being mildew resistant, it attracts butterflies. It's great as a border specimin and as a cut flower.

(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.

Boltonia asteroides Boltonia asteroides
(False chamomile)
Be the first to rate this plant
Hardiness Zones: 1 2 3 4 5 6 7 8 9 10 11

Boltonias are vigorous perennials grown for their sprays of aster-like flowers, which appear above clean, gray-green foliage. Their vigorous nature makes them suitable for naturalizing. They are also great in the border (and for cutting), but will benefit from frequent dividing to keep in bounds, and may be cut back in late spring for more compact plants.

Boltonia asteroides 'Snowbank' Boltonia asteroides 'Snowbank'
(False chamomile)
(1 user review)

Boltonias are vigorous perennials grown for their sprays of aster-like flowers, which appear above clean, gray-green foliage. Their vigorous nature makes them suitable for naturalizing. They are also great in the border (and for cutting), but will benefit from frequent dividing to keep in bounds, and may be cut back in late spring for more compact plants. 'Snowbank' produces masses of white flowers in late summer.

Darmera peltata Darmera peltata
(Indian rhubarb, Umbrella plant)
Be the first to rate this plant
Hardiness Zones: 1 2 3 4 5 6 7 8 9 10 11

Darmera's flower stalks emerge from the ground on naked stems in spring, and are followed by cupped, rounded but indented leaves up to 24 inches across. The foliage forms a lovely, vase-like clump, 4 feet tall and 3 feet wide. The flower clusters are composed of many 5-petaled, starry, pink or white florets with conspicuous stamens. This native of the western U.S. is found growing along woodland stream banks, and helps to add a tropical look to temperate gardens. Darmera makes a distinct and long-lasting foliage statement in moist conditions, and exhibits autumn color also. 

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

Summer-long bloom and a tough constitution make the mat-forming ice plant a perfect groundcover. Two-inch magenta blossoms with white anthers are produced in midsummer and late summer.

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

Long-lasting, terminal clusters of lime green bracts and flowers punctuate the meandering 'arms' of this ground-hugging species. The chalky seafoam foliage looks great spilling over a stone wall in a rock garden or at the edge of any bed.

Helleborus 'Ivory Prince' Helleborus 'Ivory Prince'
(Hellebore)
(1 user review)
Hardiness Zones: 1 2 3 4 5 6 7 8 9 10 11

Year-round gray-green foliage persists through shade and snow and is fairly deer and rabbit resistant. Flowers appear in early spring with daffodils and tulips. This cultivar produces flowers that sit well above the foliage and point upward, which adds to its showiness.

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

Heuchera 'Caramel' has H. villosa parentage, so it's more tolerant of heat and humidity that other heacheras. It has glowing, apricot-hued foliage that grows up to 12 inches tall and 20 inches wide. Pink flowers appear in spring. This plant performs well in both garden beds and containers, or as a groundcover when planted en masse. It may be evergreen on warmer climates.

'Midnight Rose' is a striking heuchera with burgundy leaves heavily splashed with hot pink. The plant grows to 10 inches tall and 16 inches wide and produces small flowers in spring, though this plant is grown primarily for its foliage.

Persicaria polymorpha Persicaria polymorpha
(Giant fleeceflower)
(1 user review)
Hardiness Zones: 1 2 3 4 5 6 7 8 9 10 11

This massive herbaceous shrub needs a lot of room to show off its vase-shaped form, but it does not spread or self-sow like some of its relatives. It blooms close to the ground from June and continues throughout the summer atop 6-foot-tall stems. The large, white, astilbe-like blossoms fade to pink and then reddish-brown as the season comes to a close.
