'''Heartleaved Foamflower''' or '''Allegheny Foamflower''' (''Tiarella cordifolia''), is a [[herbaceous]] plant commonly used as shrubbery. It grows in most kinds of soil and blooms from April to June.

{{Inc|
Tiarella cordifolia, Linn. Foam-flower. A handsome native perennial, forming a tufted mass, 6-12 in. high, of broadly ovate lobed and serrate lvs. and simple erect racemes of white fls. borne well above the foliage in May. Fls. about 1/4 in. across; petals oblong, clawed, somewhat exceeding the white calyx-lobes. In rich, moist woodland, Nova Scotia to Ont., south to Ga.—An elegant plant well worthy of general cult. It is a lover of cool shaded places and of rich moist soil. It will do well, however, in ordinary soil and flower freely in a half-shaded place, but the varied lf.-markings of bronzy red and other signs of luxuriance are not brought out to their fullest extent except with moisture, coolness and a fairly rich soil. The plant forces well and easily in a coolhouse for early spring flowering. It is tenacious of life and generally easy to manage. 

Var. albiflora, Hort., is a fine white-fld. form. 
Var. purpurea, Hort. (T. purpurea, Hort.), is a purple-fld. form, of which the following variations are also offered in the trade: purpurea major, with salmon-rose or wine-red fls.; purpurea major compacta, a more compact grower with bronzy chamois-colored fls.; purpurea marmorata, with very attractive bronze foliage passing to blackish green and marbled with purple: fls. very numerous, maroon.
