Description
Heuchera americana is a small evergreen perennial with lobed, semi-palmate, green, purple, or brown leaves that may or may not be veined or marbled. It grows up to 2 feet (60 cm) tall and wide.
Loose, up to 3.3 feet (1 m) tall racemes of insignificant green to cream flowers bloom in late spring or early summer.
Hardiness
USDA hardiness zone 4a to 9b: from −30 °F (−34.4 °C) to 30 °F (−1.1 °C).
How to Grow and Care
These plants are generally considered easy to grow and require little routine maintenance. Deadhead the spent flower spikes as needed to encourage continuous flowering or repeat blooming. The molding will help keep the soil moist and prevent injury to the shallow root system from heat during the summer months. Coral Bells can be divided every 3 to 4 years if they lose vigor or when the crown gets too large.
Coral Bells prefer to be planted in locations with fertile, moist, well-drained soil. They particularly do not perform well in locations with poor drainage during winter. Most Heuchera cultivars will grow more vigorously and have the best leaf coloration when planted in locations with partial shade, particularly in the afternoon. Purple-leafed cultivars can tolerate more direct sun; in general, the darker the purple coloration, the more exposure to sun they can tolerate. Conversely, the amber and gold-leafed cultivars are less sun-tolerant; the more yellow the leaf coloration, the less tolerant they are to the sun. Most cultivars will usually survive in locations with full sun or full shade, but they will be smaller and not look as lively.
