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

A stunning, native dune grass, 'Dewey Blue' is perfect for coastal areas as well as inland gardens. Heat, drought, and humidity won't faze its noticeably graceful habit. This grass has exceptional blue foliage and a vigorous constitution. Airy, light beige flowers emerge in late summer and fall, persisting well into winter for a long season of interest. 'Dewey Blue' grows 4 to 5 feet tall and almost as wide.

'Prairie Fire' is a distinctly red form of switchgrass. Blue-green spring foliage turns shades of deep red by early summer and butter yellow in late fall. The grass persists into winter. 'Prairie Fire' has a fibrous root system that grows to more than 10 feet deep, making it drought tolerant. -Scott Vogt, Native grasses, Fine Gardening issue #124

Panicum Ruby Ribbons’ soft blue-green foliage emerges in the spring on upright, clumping plants. The foliage takes on a wine-red color in early summer, which intensifies as the season progresses. Flower heads appear in late summer, followed by ornamental seed heads, which, if left uncut, provide long-lasting winter interest.

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

'Shenandoah' is truly a plant for all seasons. In early summer, its leaf blades are tipped in red, and by autumn, the entire leaf is a rich burgundy color, topped by pink plumes. In winter, the leaf color fades to beige; the blades persist and offer cover to birds. 'Shenandoah' is a compact selection of an American native prairie grass. -Chris Kelley, Regional Picks: Midwest, Fine Gardening issue #120

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

The flowers of vesper iris open in the late afternoon over a period of several minutes, just about the time the sound of evening vespers might have wafted over an old monastery garden. It is a valuable addition to the garden also because of its late blooming season (high summer into early fall) and for its ability to bloom from seed started the same spring. The vesper iris has typical iris-looking leaf fans and abundantly branched, willowy bloom stalks rising to 4 feet. The inch-wide flowers range in color from pure white to violet.

A refreshing new look to an old time favorite ornamental grass! Pennisetum ‘Fireworks’ is the first variegated purple fountain grass. The midvein is the typical burgundy color and is flanked by hot pink margins. Produces beautiful red-burgundy foxtail flowers. Great accent plant and excellent in containers. -Santa Rosa Gardens

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

Penstemon palmeri Penstemon palmeri
(Palmer's penstemon)
(1 user review)
Hardiness Zones: 1 2 3 4 5 6 7 8 9 10 11

A native of the Southwest, Palmer's penstemon sports sharp, prickly, gray leaves and thrives in the harsh conditions. Snapdragon-like pale pink flowers boom in late spring or early summer, and their sweet-honey scent attracts bumblebees. Toothed, sage green leaves skirt the upright stems for the rest of the gardening season.This perennial wildflower is one of the largest penstemons. It looks good in the back of a border or as a focal point, perhaps near a path where its fragrance can be enjoyed or in an informal grouping with other native penstemons and grasses, or with other plantss that have similar maintenance and water requirements. -Katie Nicolich, Plants to know and grow, Fine Gardening issue #120

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.

This pure white phlox is valuable in the garden because of its abundant, fragrant flowers, its sturdy growth habit, and its resistance to powdery mildew. Growing to about 3 ½ feet tall and 2 to 3 feet wide, it blooms from early summer to early fall. It needs a consistently moist soil. Use it in a border or cottage garden. It will glow at dusk.

Pale yellow, four-inch-long flowers dangle all around the stems of this evergreen, fuchsia look-alike. Given a long enough growing season, it can reach 5 feet tall and as wide. Where not hardy, grow it as a tender perennial.

Physocarpus opulifolius 'Seward' Physocarpus opulifolius 'Seward'
(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.
