Description
A North American native grass, Side Oats Grama is a rarity among ornamental grasses in that it sports actual flowers when in bloom. Inflorescences of purplish-tinged flowers appear on arching stems above the foliage in early to mid summer. These bracts hang uniformly from one side of the stem while brilliant red-orange anthers dangle below and delicate white stigmas protrude above. These inflorescences fade to tan as the seeds mature having a distinctly oat-like appearance when dry. The narrow, bluish-gray leaf blades form a dense clump growing 18 inches tall with flowers rising to 3 feet. Fall bring golden foliage that sometimes develops interesting hues of orange and red. An excellent texture plant that anyone can grow!
Wildlife Assets
Side Oats Grama Grass it is cited as a food source or larval host for at least five types of skipper moths. It also feeds many bird species throughout the winter months and provides nesting material.
Landscape & Garden Uses
Growing 2 to 3 feet tall with a spread of 1 to 2 feet wide, Side Oats Grama Grass is ideal for use as an accent in smaller garden spaces or in groupings or mass plantings in larger spaces and on slopes where it provides excellent contrast and texture almost year-round. Oddly enough, Side Oats Grama Grass can also be grown as a lawn that can be mown regularly to a height of 2 to 4 inches tall. A fine addition to ornamental grass gardens, native plant gardens, bird and wildlife gardens, prairie gardens and cottage gardens.
Suggested Spacing: 2 to 3 feet apart for mass plantings; 5 feet or more apart for space between plants

Growing Preferences
Side Oats Grama Grass are exceptionally easy to grow in most any type of soil from sandy to heavy clay. It prefers a moist but well-drained soil of average fertility but is also tolerant of dry soils. We suggest at least 6 hours of direct sunlight per day for best overall performance. We usually leave the foliage and the seeds in place during the winter to provide food for birds, winter interest in the landscape, and to protect the crowns. We cut plants back to the ground in late winter or early spring before new growth begins to emerge from the ground. We’ve seen absolutely no problems with insects or disease.
