1.Coral Bells — Overview
Heuchera sanguinea, commonly known as Coral Bells or sometimes Alumroot, is a captivating herbaceous perennial belonging to the Saxifragaceae family. This species is celebrated for its remarkable ornamental value, primarily due to its vibrant, diverse foliage and delicate, airy flower stalks. It typically forms a neat, compact basal mound of leaves, reaching an average height of 30 to 45 cm (12 to 18 inches) with a spread up to 60 cm (24 inches) in diameter.
The leaves, which are the plant's most striking feature, are typically heart-shaped to rounded, often deeply lobed or scalloped, and can measure up to 10 cm (4 inches) across. Their color palette is astonishingly broad, encompassing shades from deep burgundy, rich chocolate, and bronze to bright lime green, soft peach, and shimmering silver, frequently adorned with contrasting veins or margins that enhance their visual appeal. The texture of the leaves can vary from glossy to matte or subtly ruffled, contributing to its dynamic presence as an excellent ground cover in various garden settings.
From late spring through early summer, slender, wiry flower stalks gracefully emerge, rising significantly above the foliage to heights of 60 to 90 cm (24 to 36 inches). These elegant scapes bear numerous small, bell-shaped flowers arranged in loose panicles. The blooms typically range in color from pristine white and soft pink to vivid coral and deep crimson, which directly inspired its popular common name, 'Coral Bells'.
These nectar-rich flowers are a significant attraction for pollinators, especially hummingbirds and various bee species, adding a lively ecological dimension to the plant's aesthetic. Native to the southwestern United States, specifically Arizona, New Mexico, and parts of Texas, extending into northern Mexico (Sonora), Heuchera sanguinea thrives in rocky, shaded woodland areas, canyon walls, and forest understories. It prefers filtered light and well-drained, humus-rich soils, making it an ideal choice for similar garden environments.
Taxonomically, it was previously known by synonyms such as Heuchera pulchra and Heuchera sanguinea var. pulchra.
