Rhizomatous and stoloniferous, forming mats to 1m or more wide. Leaves 6-10cm long, broadly ovate-cordate, broadly five-lobed, toothed and hairy, often flecked deep maroon especially along the main veins, bronze-flushed in winter. Flowers 2.5-5mm long, white or sometimes pink-tinted especially in bud, in fairly dense racemes, 15-30cm high, late spring to early summer. Eastern North America, New Brunswick to Ontario south to Tennessee, in moist woods. T.c. forma parviflora has smaller flowers, and in forma tridentata the petals are three-toothed (the commonest form in British gardens). T.c. 'Major' produces pink to wine-red flowers. 'Marmorata' has bronze foliage that ages very dark green with purple marbling. 'Purpurea' has purple flowers. T.c. var. collina is a synonym of T. wherryi (q.v.) but the plant under this name in British gardens appears to be a clump-forming, non-stoloniferous variant of cordifolia with plain green leaves.
