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.

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

'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

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

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.
