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

'Husker Red' is one of the few penstemons that does well in wet winters and hot, humid summers. Ruby-toned leaves appear in spring, followed in late spring and early summer by 3-foot-high stems adorned by panicles of white blooms.  The flowers attract bees, hummingbirds, and butterflies, but the plants are not magnets for deer or rabbits. In autumn and winter, songbirds feast on the seed. For a stunning display, plant 'Husker Red' in groups. -Chris Kelley, Regional Picks: Midwest, Fine Gardening issue #120

(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.

(Summer Wine ninebark)
(1 user review)
Hardiness Zones: 1 2 3 4 5 6 7 8 9 10 11

Many gardeners know ninebark as an undistinguished shrub with ordinary green leaves, white flowers, and fall fruit. But 'Seward,' sold under the trademark name Summer WineTM, has outstanding burgundy leaves and pink flowers that bloom in early summer. This plant is super tough and makes a stunning focal point in a summer border.

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

The yellow to lime green foliage of 'Nugget' ninebark makes an interesting contrast with the exfoliating, cinnamon-colored bark. Clusters of white flowers appear along the stems in early summer, followed by dark brown seed capsules, which add winter interest. Unsheared, the plant has a vase-shaped growth habit. -David Graper, Regional Reports: Upper Plains, Fine Gardening issue #122
