Description

Island Alum Root is a two foot perennial with 3' spikes of small pinkish flowers emerging from February to April. Native to the Channel Islands. This alum root likes part to full shade. A good edging plant in a shady border. The large 3"to 5" dark green leaves and spikes of small pinkish flowers make it appear very delicate but it's surprisingly drought tolerant. These plants are very lush near the coast as long as salt spray doesn't reach them. Deer eat this only when they are in extremely high populations. This Heuchera species is hardy to about 12 degrees F. It is the preferred groundcover under evergreen oaks in California. Beautiful in massed plantings under evergreen oaks. Plant about 2' apart with shredded redwood bark or shredded cedar bark as a 2"-4" mulch, unless there is sufficient oak leaves to use as mulch.
