Tiarella for the Garden

tiarella-tiger-stripe lgTiarellas, commonly called foamflowers, are popular perennials for shade gardens. . There are about six species five of which are native to North America and one to Asia.  The plants produce short spikes of small white to pink flowers above a low growing mound of handsome foliage. The evergreen leaves may be almost round or have three to nine lobes that may be rounded or angled, and slightly to deeply cut. In summer the leaves are green often with maroon to purple markings along the veins and in winter they turn shades of bronze. Plants may be clump forming or spreading.

Breeders have produced many different cultivars that vary primarily in leaf shape and leaf markings but also show differences in flower color, hardiness, and heat-humidty tolerance. Here are some of the best.
