Coral bells
Heuchera sanguinea Engelm.
Description
Coral bells (Heuchera sanguinea) is a perennial herbaceous plant belonging to the Saxifragaceae family. This species is highly valued in horticulture for its neat basal rosettes of foliage and dainty, bell-shaped flowers that bloom on slender stalks throughout the early to mid-summer season.
Native to the southwestern regions of North America, specifically the mountainous areas of Arizona and New Mexico, this plant has become a staple in ornamental gardening worldwide. It serves as a parent species for numerous hybrids that exhibit diverse leaf colors and improved blooming characteristics.
Botanically, the plant features heart-shaped or rounded leaves with lobed edges. The growth habit is compact, typically reaching 20 to 50 centimeters in height. The inflorescences are loose panicles containing many small, intense red, pink, or white flowers that provide a delicate texture to floral displays.
Cultivation requires well-draining, fertile soil with a neutral to slightly alkaline pH. The plant performs best in partial shade, where it is protected from harsh midday sun. Essential care practices include consistent moisture without saturation, regular mulching to protect the shallow root system, and light spring fertilization.
The primary use of Heuchera sanguinea is in landscaping, particularly for border planting, rock gardens, and container arrangements. Growers should remain vigilant against common pests like vine weevils and prevent fungal infections such as root rot by ensuring the planting site has excellent drainage.
