‘Miracle’ is a vigorous, clump-forming coral bells cultivar that is noted for the changing colors of its leaves. The lobed, rounded leaves form a basal mound (to 8” tall) which may spread to 10-15” wide. Leaves emerge chartreuse in spring with red splotches in the center, but mature by summer to deep red with yellow on the margins. Leaves are silvery underneath. Tiny, light pink flowers appear in spires in early summer (later than most heucheras) on slender stems rising above the foliage mound, typically to 18” tall. U. S. Plant Patent Applied For (PPAF).
