Tiarella cordifolia

Tiarella cordifolia L.

Heartleaf Foamflower, Heart-leaf Foamflower

Saxifragaceae (Saxifrage Family)

Synonym(s):

USDA Symbol: TICO

USDA Native Status: L48 (N), CAN (N)

Long, slender stamens give heart-leaf foamflower�s spikes of white flowers a frothy appearance. The small, star-shaped flowers occur in compact racemes on 6-16 in. stalks rising above a mound of attractive, lobed leaves. The flower stalk lacks leaves in the northeastern part of the plant�s range, but bears heart-shaped leaves in the South. Mature plants send out runners, creating sizeable colonies with time. This is a perennial plant. Small, white to pinkish flowers are in a feathery, somewhat elongated, terminal cluster.

This attractive wildflower, which spreads by underground stems, forms colonies, and makes excellent groundcover for shady, wooded sites. The tiny flowers and fine texture of the stamens resemble foam and account for the common name. The genus name is from the Greek tiara, designating a turban once worn by the Persians, and refers to the shape of the pistil.

Seed Collection: The small black seeds are generally ready for collection about one month after the first flowers open. There will be progressive maturation of seed from the bottom of the stalk to the top. Cleaned seeds should be stored in sealed, refrigerated containers.
Seed Treatment: No special treatment is necessary.
Commercially Avail: yes
