Tiarella trifoliata, commonly called threeleaf foamflower,[1] laceflower,[2] or sugar-scoop,[2] is a dicot in the family Saxifragaceae. It is a perennial herb that grows in the late spring. It is endemic to the low to moderate elevation moist forests of western North America.
The flowers are bell-shaped, white, solitary from an elongate, leafless panicle. The calyx lobes are 1.5–2.5 mm and petals are 3–4 mm. Basal leaves are 15–80 mm long and up to 120 mm wide, trifoliate or palmately 3- to 5-lobed. Cauline leaves are infrequent and much smaller.[1]
There are three varieties of T. trifoliata:
- T. trifoliata var. trifoliata, which has leaves that are irregularly lobed, with coarse teeth.
- T. trifoliata var. unifoliata, which has simple leaves.
- T. trifoliata var. laciniata, which is confined in its range from Washington only as far north as Vancouver Island, and has deeply lobed leaves.[3]
