Aster novae-angliae ‘Purple Dome' Aster novae-angliae ‘Purple Dome'
(New England aster)
(9 user reviews)
Hardiness Zones: 1 2 3 4 5 6 7 8 9 10 11

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.

Aster oblongifolius 'October Skies' Aster oblongifolius 'October Skies'
(October skies aster)
(2 user reviews)
Hardiness Zones: 1 2 3 4 5 6 7 8 9 10 11

'October Skies' is a dwarf aster that is low to the ground and mounding. It flowers in the fall when most other plants have finished for the season, covering itself with hundreds of dark sky-blue flowers.

Aster tataricus Aster tataricus
(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.

Dennstaedtia punctilobula Dennstaedtia punctilobula
(North American hay-scented fern)
Be the first to rate this plant
Hardiness Zones: 1 2 3 4 5 6 7 8 9 10 11

This fern's lacy foliage smells of freshly mown grass and carpets the woodland or a moist, partially sunny site. The green lushness turns golden in the fall. It is a good choice for rapid naturalizing. Use in a woodland garden or near water features.

Digitalis obscura Digitalis obscura
(Sunset foxglove, Willow-leaved foxglove)
Be the first to rate this plant
Hardiness Zones: 1 2 3 4 5 6 7 8 9 10 11

This foxglove has long-lasting flowers in seductive shades of burnt umber. Its glossy, linear leaves are evergreen in mild climates, but turn brown in colder climates.

(Blue fescue, Gray fescue)
(1 user review)

These compact tufts of 8-inch-long powder-blue leaves are well suited for edging and naturalizing in the rock garden. 

Galanthus elwesii Galanthus elwesii
(giant snowdrop)
Be the first to rate this plant
Hardiness Zones: 1 2 3 4 5 6 7 8 9 10 11

The giant snowdrop has larger flowers and broader leaves than the more common G. nivalis, but grows to the same 4 inches tall and wide. Its white, nodding blooms appear in late winter, signalling spring around the corner.

Galanthus nivalis Galanthus nivalis
(common snowdrop)
Be the first to rate this plant
Hardiness Zones: 1 2 3 4 5 6 7 8 9 10 11

Snowdrops are some of the earliest bulbs, and flowers in general, to bloom in spring. Galanthus nivalis is the most common species, and its cultivars are the most commonly grown snowdrops on the market. They are reliably hardy and perennial. They grow to 4 inches tall and wide and flower in mid- to late winter, long before most other plants. They are the first sign of spring around the corner. Flowers are nodding and white.

Helleborus × hybridus cvs. Helleborus × hybridus cvs.
(Hellebore)
Be the first to rate this plant
Hardiness Zones: 1 2 3 4 5 6 7 8 9 10 11

From late fall through winter, the leathery leaves of hellebores stay glossy, cheery, and green. Hybrids of H. orientalis and other species have a clump-forming habit and leathery leaves. They begin blooming in February or March in a range of shades, adding much needed color very early in the season. The blooms last for a very long time, especially if the weather stays cool. Hellebores are tolerant of summer heat and humidity. -Marty Hair, Regional Picks: Upper Midwest, Fine Gardening issue# 127

Helleborus odorus 'Double Queen' Helleborus odorus 'Double Queen'
(Lenten rose, hellebore)
(1 user review)
Hardiness Zones: 1 2 3 4 5 6 7 8 9 10 11

Hellebores begin blooming in mid-winter in a range of colors, adding much needed color very early in the season. They bloom when the temperature is below freezing, even amidst the snow. Protect from cold winter winds, especially when not insulated by snow, to avoid damaged foliage. Avoid ingestion of all plant parts and contact with the sap.

('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. Grow it in garden beds, as an edger, or in containers, where it will blend well with a multitude of other plants.
