‘Lime Marmalade’ is a clump-forming, coral bells hybrid. It originated as a sport from Heuchera 'Marmalade'. It is most noted for its ruffled lime green leaves that retain good color throughout the growing season. Foliage typically forms a basal mound to 8-10” tall and to 15-18” wide. Flowers borne in open, airy panicles appear in spring on slender, wiry stems rising above the foliage mound, typically to 14-16" tall.
