Tiarella cordifolia, the heartleaf foamflower,[1] heartleaved foamflower, Allegheny foamflower, false miterwort, or coolwort, is a species of flowering plant in the saxifrage family, native to North America. It is a herbaceous perennial which is valued in cultivation for its erect stems of foamy cream flowers in summer.
Description
Tiarella cordifolia has a scaly horizontal rhizome and seasonal runners?. The leaves are 5–10 cm (2–4 in) long, basal, long stalked, hairy, with 3-7 shallow lobes, and heart-shaped at the base. They are dark green usually mottled with brown, rough-hairy above and downy beneath. They have long flowering stems that can grow as tall as 30 cm (12 in). The flowers are white, small and feathery and form a long terminal cluster on a leafless stalk. The inflorescences are 15–30 cm (6–12 in) tall, with the flowers borne in close, erect racemes. The flowers have 5 petals (entire) and 10 stamens (long and slender), giving the flower cluster a fuzzy appearance. The two unequal seed capsules split along their inside seams, releasing several pitted seeds.[2]
This tiarella spreads well by rhizomes, unlike other cultivated tiarellas, but lacks the invasive tendencies of many more commonly employed groundcovers. Its habitats include deciduous woods and stream banks.[3]
The flowers are visited by small bees, syrphus flies, and butterflies that may affect pollination.
This plant has gained the Royal Horticultural Society's Award of Garden Merit.[4][5]

Origin of name
The Latin specific epithet cordifolia means “heart-shaped leaves”.[6] In fact, "tiarella", in French, can be translated "crown" (tiare). The little fruit produces by the plant looks like a "tiare" - a crown.
