Rhizome scaly; bulblets 0. |
Members of this genus are typically rock dwellers, often found growings where soil has collected in the fissures. A Perennial, characterized by clusters of leathery, oval or heart-shaped leaves, growing directly off the root crowns on petioles. The small, cup-shaped, five-petaled, light pink to greenish white flowers are arranged on leafless stalks that extend well above the plant. The taproot is large and has a scaly brown skin. [Tilford]

Cultivation &
Propogation
"Seed - sow early spring in a warm greenhouse and only just cover the seed. Germination is usually fairly rapid. Prick out the seedlings when they are large enough to handle and plant them out into their permanent positions in late spring or early summer. The seed can also be sown in the middle of spring in an outdoor seedbed and planted out in early summer. Alternatively, you can sow the seed in an outdoor seedbed in the middle of summer for planting out in the following spring. Division in March or October[1, 111]. It is best to divide the plants in August or early September, making sure that the woody roots are planted quite deeply with only the crown of foliage above the ground[233]." [PFAF]
Groundcover: "A good ground cover plant for the woodland garden[200]. [PFAF]
Succeeds in any good sweet garden soil that does not dry out in spring[1]. Prefers full sun but tolerates partial shade[1, 111]. Prefers a well-drained fairly rich and not too heavy soil[111]. Apt to hybridize with other members of this genus[111]. A very ornamental plant[60]." [PFAF]
Habitat / Range "Moist to dry streambanks, rock crevices and talus slopes from the lowland to subalpine zones; infrequent in NW BC, frequent on Vancouver Island and the adjacent mainland; S to WA and CA." [IFBC-E-flora]
Origin Status: Native. [E-flora]
"Heuchera micrantha is an evergreen Perennial growing to 0.6 m (2ft) by 0.4 m (1ft 4in).
It is hardy to zone 5 and is not frost tender. It is in leaf 12-Jan It is in flower from Jul to August, and the seeds ripen from Aug to September. The flowers are hermaphrodite (have both male and female organs) and are pollinated by Bees. [PFAF]

Ecological Indicator Information
"A shade-tolerant/intolerant, submontane to subalpine, Western North American forb distributed more in the Pacific than the Cordilleran region. Occurs in maritime to submaritime cool mesothermal climates on nitrogen-rich soils; its occurrence decreases with increasing elevation and continentality. Scattered in non-forested communities and open-canopy forests on water-shedding (colluvial) and water-receiving (seepage and stream-edge) sites. Characteristic of Moder and Mull humus forms."

Cultivation
Succeeds in any good sweet garden soil that does not dry out in spring[1]. Prefers full sun but tolerates partial shade[1, 111]. Prefers a well-drained fairly rich and not too heavy soil[111]. Plants are hardy to about -15°c[187]. Apt to hybridize with other members of this genus[111]. This species is probably best treated as a sub-species of H. micrantha. [PFAF]
Groundcover: A good ground cover plant for the woodland garden[200]. Plants should be spaced about 30cm apart each way[208]. [PFAF]
