Tiarella cordifolia
Also called Heartleaved foamflower, Foamflower, False Mitrewort, Heart Leaf Foamflower, Heart Leaved Foamflower, Allegheny Foamflower, Creeping Foamflower
Heartleaf foamflower is a low, spreading woodland perennial with heart-shaped leaves and fuzzy white flower spikes in spring. It grows best in cool, shaded, moist but well-drained soil and is valued as a groundcover under trees.
Tiarella cordifolia, the heart-leaved foamflower, is a species of flowering plant in the family Saxifragaceae. The specific name cordifolia means "with heart-shaped leaves", a characteristic shared by all taxa of Tiarella in eastern North America. It is also referred to as Allegheny foamflower, false miterwort, and coolwort.
Historically, the name Tiarella cordifolia has referred to the one and only species of Tiarella in eastern North America, but in 2021, the species was split into multiple taxa, which caused the name to have a different meaning. For clarity, the qualified name Tiarella cordifolia sensu stricto (abbreviated s.s.) refers to the new taxon while Tiarella cordifolia sensu lato refers to the old taxon.
Tiarella cordifolia has gained the Royal Horticultural Society's Award of Garden Merit. It spreads well by rhizomes, unlike other cultivars of Tiarella, but lacks the invasive tendencies of many more commonly employed groundcovers.
Tiarella cordifolia 'FM Mooberry' is named after F. M. Mooberry of the Brandywine Conservancy.
In eastern North America, Tiarella cordifolia sensu lato is wide-ranging, from northeastern Wisconsin across southeastern Canada to Nova Scotia, extending southward through the Appalachians into Alabama and Mississippi:
