Key Lime Pie Coral Bells

Key Lime Pie coral bells is a clump-forming perennial grown for bright lime or chartreuse foliage and small pale-pink flowers. A Proven Winners listing gives a mature size of about 12 inches in both height and spread, while the Missouri Botanical Garden describes a foliage mound around 8 inches tall with flower stems reaching about 16 inches and a 12–18-inch spread.

Slender stems carry pale-pink flowers from late spring into summer. ## Growing conditions Grow in well-drained soil with steady moisture, especially in hot or sunny sites. The cultivar can take sun or partial shade, but the Proven Winners guidance cautions against prolonged intense sun combined with drought. Its listed hardiness spans USDA zones 4–9. ## Landscape use Use the bright leaves to lift a shade border, edge a path, or add contrast in a container. The clumping habit works in small groups and alongside darker-leaved coral bells. ## Maintenance Remove scorched leaves as needed and keep the crown in free-draining soil. Missouri Botanical Garden notes that heucheras may heave in freeze-thaw weather, so check the crown in spring and settle it back into the soil if it has lifted.
