Stipa ichu, Peruvian feather grass. Plant together with Russian sage for a dramatic look!Grow in a moderately fertile well-drained soil. Cut back plants in late winter to rejuvenate. Use it as a vertical accent in a mixed border or rock garden, or among shrubs and rocks on a hillside. Hoe the soil to prevent seedlings from spreading across the landscape. However, a field or bed packed with Peruvian feather grass is magnificent in autumn! Use it as an annual in cold winter regions.
