(='Rubra') An unusual and dramatic grass, slowly forming a low clump. Leaves are green at the base, with red tips that become more intense over the summer and fall until they appear to glow. Effective as an edging, in the rock garden, and especially when mass planted. Although this prefers moist soil, plants require good drainage, especially in winter. Remove any all-green shoots if they appear. Clumps may be easily divided in the spring. Seldom flowers.
