Overview

The Island Alum Root, Heuchera maxima, thrives in USDA zones 8-10. A semi-evergreen perennial, it boasts broad, scalloped leaves and tall, airy flower spikes. With a modest spread of up to 2 feet and height of around 3 feet, these plants are ideal for edging and ground cover in partial shade. The cream-colored blossoms, appearing in late winter to spring, attract hummingbirds, adding dynamic interest to shade gardens.
