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" 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.
