I am want to try to grow either goose bumps or knuckle head pumpkins this spring, anybody try them before and where's the best place to buy seeds?
If you wish to go the source, Siegers developed and patented the Super Freak series. If you only want a small amount, just check with your normal vendor. Lots of vendors carry Knucklehead and/or Goose Bumps.
