Same as above except pure white flowers-nice addition to the garden edge or rock garden. These rhizomatous, clump-forming plnts are semi-evergreen with grass like foliage. They are ideal for the rock gardens or in desert gardens or used as an edging in the perennial boarder. The Iris like leaves are linear with upright stems bearing flat-cup shaped, white flowers with yellow throats. Blooms in summer. Use in full sun in normal to moist soils.
