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

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.

(Vesper iris)
Be the first to rate this plant
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.

The velvety leaves of this choice species are pale green with long, silky hairs. The angora-like feel of the foliage is matched by its heavenly aroma of fresh mint. It bears clusters of dainty white blossoms in spring, but remains an exceptional foliage plant throughout the year.

(1 user review)

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

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

The Volcano® series of fragrant, abundantly-flowering, compact Phlox has been bred for high levels of natural disease-tolerance. This is wonderful news for Phlox fans, who until now have often had to deal with powdery mildew when growing other Phlox varieties. -Anthony Tesselaar Plants
