Description
Romanzoffia –
There are about 5 mat or mound forming, clump forming annuals or perennials, in the waterleaf family, in this genus. They occur in shaded, rocky, alpine, or woodland habitats in Western North America and the Aleutian Islands. They produce tufts of rounded or kidney shaped, lobed or deeply scalloped, leathery leaves which seldom exceed 2″ long. Leaves die back after flowering and re-emerge in autumn. The bell shaped flowers, each with 5 rounded petal lobes and conspicuous anthers, are borne in raceme like cymes in late spring or summer. Suitable for a woodland garden or rock garden.
Grow in moist but well drained, humus rich, neutral to acidic soil in deep or partial shade. Divide in early spring.
Prone to snails and slugs.
