Until now, this giant sized hosta from the late Mildred Seaver has never been commercially available. In fact, it was once auctioned off for $725 at a fundraiser! ‘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. Mildred Seaver was known among hosta enthusiasts as the “Queen of Hostasin . In her lifetime, she registered 95 new varieties including: ‘Spilt Milk’, ‘Queen of the Seas’, and ‘Komodo Dragon’.
