Until recently, this giant sized hosta from the late Mildred Seaver was never commercially available.  In fact, it was once auctioned off for $725 at a fundraiser!  Now you can be one of the special few to own this fantastic hosta. 

‘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 Hostas”.  In her lifetime, she registered 95 new varieties including: ‘Spilt Milk’, ‘Queen of the Seas’, and ‘Komodo Dragon’.
