Description

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 veination. 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. Though attractive, the flowers are not the most remarkable aspect of the species.

Cultivation

Best grown in filtered light, American alumroot is tolerant of deep shade, or full sun in the northern part of its range. It prefers rich soil that is kept consistently, but is really quite adaptable and will even tolerate poor, rocky soil. It can be used as an accent plant when mixed in with other perennial, or as an effective ground cover when planted in large groups. Zones 5-8

Propagation

Can be propagated from seed, but they are tiny and difficult to collect. Can be propagated by crown division in early spring as the leaves begin to emerge, or fall once the plant has gone dormant.
