Fountain Grass (purple)

Height: 12-36 inches
Position: Full sun to very light shade
Soil: Fertile, moist, wet, or well-drained soil

Fountain Grass is an upright-open, mound forming plant. This is an excellent ornamental grass. It should be used as an accent or specimen plant, in the middle of borders. A mass planting produces a colorful display when in full bloom. Fountain Grass does well as a transitional grass between formal and natural areas. Flowering occurs in July and goes through the fall. Flower color changes from whitish purple to coppery purple. Fall foliage is yellow-gold.
