Heuchera 'Lava Lamp' Height 16”, Spread 28”, Sun-Shade, zones 4-9. Forms a large, billowy mass of very large, coppery purple leaves with deep purple undersides. The newest leaves emerge a bright copper orange color and then deepen to coppery purple as they age. Deep purple scapes carry wands of closely spaced cream flowers in summer on 32-36” scapes. This is a Heuchera villosa hybrid, which is large, and exhibits an increased tolerance of high heat & humidity. Photo - Walters Gardens, Inc.
