‘Humpback Whale’ forms a massive, dome-shaped mound of blue-green, corrugated, heart-shaped leaves. Its color is bluest in the springtime. Blue-green scapes carry near-white, bell-shaped flowers in early summer. This plant is newly on the market as it was sold privately and at one point sold for $745 at auction! If you’re a collector you’ll defiantly want this plant in your yard!
