June Grass is also known as Prairie Junegrass. This native, widely-distributed prairie grass will flower earlier than many other upland prairie grasses. Its plumes of silvery-green seed heads turn tan by mid-summer. The foliage supporting these seeds is also an attractive green-gray color. June Grass actively grows during the spring and fall when soil temperatures are cool. Its preference for dry, sunny conditions makes it a popular candidate for green roofs.
June Grass is easily grown in dry to medium, well-drained soils in full sun. It thrives in rocky or gritty soils, needs superior drainage and tolerates drought. Avoid wet and/or heavy soils or shade. Will self-seed in optimum growing conditions. Junegrass grows to mature height and flowers by June, but thereafter may go dormant in hot and humid summer climates. In cool summer climates, it will usually remain attractive until fall. Plants may be short-lived.
