The family Saxifragaceae comprises chiefly north temperate plants and includes many alpine and arctic species of xerophytic habit. Species and cultivars of Bergenia and Heuchera are tough and persistent, so make good border plants for cool climates. It comprises about 55 species of evergreen and semi-evergreen perennials from woodland and rocky sites in North America.
Flowers are sometimes petalless and have conspicuous, colourful calyces.
Leaves can be boldly veined and those forms possessing darker pr paler shading or variegation make excellent foliage plants. Hybrids of H. americana, H. cylindrica, H. micrantha and H. sanguinea share their parents habits and leaf characteristics to varying degrees. Heucheras can be used as groundcover plants or in a herbaceous mixed bed or border, or shrub border. The flowers attract both bees and hummingbirds and are good for cutting. Heuchera cylindrica Cultivation Grow heucheras in a fertile, moist but well-drained, neutral soil in the full sun or partial shade.
