These hybrids combine the flowering habit of coral bells (Heuchera) with the heart-shaped leaves of foamflower (Tiarella cordifolia). Most produce foliage clumps 45 in. high and about 1 ft. wide; good in shaded rock gardens or as woodland ground cover. Newer, trailing forms look great in hanging baskets or spilling over the edge of a pot; they are more tolerant of heat and humidity. Most bloom in late spring or early summer, with a possible second bloom in fall. Unless otherwise noted, all types described here produce plumes of small pink flowers.
All require well-drained, humus-rich soil; they'll quickly fail in clay soil.
