Sow and Plant
Potted plants of improved varieties are widely available in spring. Set out plants as early as possible, while the soil is still cool. Spread the roots with your fingers, and take care not to bury the crown, which can lead to rotting. Where winters are mild, heucheras also can be planted in early fall. Young plants need water when they are actively growing. A surface mulch suppresses weeds while making the plants look more attractive.

Heucheras are descended from North American native plants, and they are among the prettiest perennials for partial shade. The plants produce sprays of flowers in spring, but heucheras are primarily grown for their colorful foliage, which persists through winter in mild climates. Leaf color varies from lime green to deep burgundy, depending on cultivar. Heucheras have been hybridized with tiarella (foamflower) to produce heucherellas, which can accept more shade than most heucheras.
Heuchera flowers can be used in cut arrangements, and picking early flowers may prolong bloom time. When flowering ends, prune off old stems to better view the heuchera foliage.
Leaf scorch can occur in hot, dry weather, especially when plants are exposed to afternoon sun. Occasional diseases include powdery mildew, rust, and bacterial leaf spot.
