I know this is a vegetable forum, but I'm trying to get opinions on what heirloom watermelon I could grow that would compare to the melons I remember from my youth (1960's)? What they sell today in the stores does not compare. I get a kick out of how I have to pay 2x the price for a seeded watermelon. To me, the seedless ones just don't have much flavor. I would love to try growing something remarkably sweet and tasty here in my zone 5.
