According to the Seed Savers Exchange website, the Siberian Sweet Watermelon was evaluated by the New Hampshire Agricultural Experiment Station in 1901 along with Green and Gold, Jones’ Jumbo, Ruby Gold and Kleckley Sweet.
Of those varieties, only Siberian Sweet and Kleckley Sweet still survive today.
The Sweet Siberian Watermelon was reintroduced several years ago by Seed Savers Exchange member Glenn Drowns, who obtained seed from the USDA. The Siberian Sweet Watermelon is one of the Renewing America's Food Traditions (RAFT) Grow-out project foods.
The watermelons are a light green with apricot-colored flesh and small black seeds. If you'd like to grow them in your own garden, seeds may be purchased at Seed Savers Exchange.
