Eastern foam flower

Tiarella cordifolia

tee-ar-EL-lah kor-dih-FOE-lee-ah Audio

This native North American species has pale green heart-shaped leaves which develop bronze highlights in the autumn. In summer, it produces a profusion of starry white flowers on 4- to 12-inch spikes. It self-sows freely.

Noteworthy CharacteristicsTiarellas are at home in moist woodland environments. 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 foamy flowers can be appreciated up close or from a distance. Grow eastern foam flower as a groundcover or edger in a shady border or woodland garden. It is a great foil to early spring bulbs.

CareProvide moist, rich soil in part to full shade.

PropagationSow seed as soon as ripe or in a cold frame in the spring. Divide the rhizomes in spring.
