Heuchera americana | American Alumroot

Heuchera americana has been the source species for a number of hybrids and cultivars, developed to enhance flower production and leaf color. This is due in part to the fact that even the straight species is highly variable. The leaves are its most noteworthy feature. They form basal clumps up to 15" tall, are heart-shaped and conspicuously lobed, often with silver tones spreading from their well-defined venation. Emergent foliage has purplish hues in early spring, turning deep green when mature, and shifting to shades of yellow, red, and purple in fall. The flowers are small bells of variable color, that develop atop 18" to 24" tall stems.
