Plants in the genus Tiarella are at home in moist woodland environments of North America and East Asia. In the garden they make wonderful carpets of intricate leaves in a variety of shapes and with distinct markings. For a long period from spring into summer, the profusion of flowers can be appreciated up close or from a distance. Generally, running forms have smaller flowers than the semi-runners, and clumping forms have the showiest flowers.
Noteworthy CharacteristicsShort spikes of airy, star-shaped flowers form a foamy haze over the attractive, low-growing foliage. Grow it as a groundcover or edger in a shady border or woodland garden. They are a great foil to early spring bulbs.
CarePrefers cool, moist soil but will tolerate a variety of soils. Grow in partial to full shade.
PropagationSow seed as soon as ripe or in a cold frame in the spring; divide in spring.
ProblemsRust, powdery mildew, slugs, weevils.
