Prairie Alumroot (Heuchera richardsonii) is a groundcover plant with panicles of green flowers in late spring. They also have good fall color. They prefer average to dry soil in sun to part sun. They are best suited for drier banks where the foliage can grow to 1½ feet tall, with flowering panicles reaching to 4 feet. Companion plants include Pale Purple Coneflower (Echinacea pallida) and Prairie Dropseed (Sporobolus heterolepis).
To protect from winter cold damage, leave leaf litter in areas planted with Prairie Alumroot. In late winter, remove dead foliage. Post-bloom in mid-June, trim all flower stalks to the base of the plant.
