How to Grow Heuchera maxima

Overview

Heuchera maxima, also known as island alum root, Channel Islands coral bells, or Jill of the rocks, is a stunning addition to any garden. With its vibrant foliage and delicate flowers, this member of the saxifrage family is sure to impress.

Growing Conditions

Heuchera maxima thrives in partial shade to full sun conditions with well-draining soil rich in organic matter. It prefers cooler temperatures and is ideal for temperate climates or protected spots in hotter regions.

Planting & Care

Plant Heuchera maxima in spring, spacing plants 1-2 feet apart to allow room for growth. Water deeply when the top inch of soil becomes dry, and mulch around the base to retain moisture. Fertilize with a balanced organic blend once or twice during the growing season.

Common Problems

Watch for powdery mildew in humid conditions and treat promptly with an organic fungicide. Heuchera maxima is generally pest-free but may suffer from root rot if overwatered or planted in poorly draining soil.

Harvest or Enjoy

Enjoy the delicate, cream-colored flowers that bloom in summer, attracting pollinators to your garden. In cooler areas, the leaves of Heuchera maxima may retain their color throughout winter, providing year-round interest. If desired, propagate using softwood cuttings or division in spring.
