Heuchera maxima - Island Alum Root

Heuchera maxima is one of those California Native plants that probably deserves a spot in almost every garden. Heuchera maxima will survive in the oak understory with little or no help, though it looks a lot better with periodic summer watering. The Island Alum Root prefers an east exposure or mid day shade. Heuchera maxima tolerates most soil types, if it doesn't get too soggy. Heuchera maxima will form a clump 18 inches to two feet across. The flower stalks can be as much as two feet tall. The Island Alumb Root is hardy into the low teens.
