Island alum root. The most robust Heuchera in our opinion, this reliable native grows to 2’ tall with a 2’ spread. The lobed, heart-shaped green leaves form a basal clump and are often mottled with gray or pale green markings. Numerous cream-colored flowers appear on tall stalks from February to April and move gracefully in the slightest breeze. Plants perform best with moderate summer water but are surprisingly drought tolerant in shady situations. An exceptional choice for naturalizing under native oak trees, we recommend it with enthusiasm. Hardy to 10F. Santa Cruz, Santa Rosa, and Channel Islands.
