Mat alumroot is a tough, clump-forming perennial that adapts well to rocky slopes, borders, and woodland edges with partial shade. It produces slender spikes of creamy flowers in summer and requires very little supplemental care once established in well-drained soil. An excellent choice for native plant gardens, rock gardens, and erosion-prone slopes across western North America.
