History of the Wagner Blue Green Tomato

The Wagner Blue Green Tomato was developed by a renowned heirloom tomato breeder named Tom Wagner, the owner of Tater Mater Seeds. Wagner bred the Green Zebra tomato, which he crossed with the Indigo Apple tomato to create the Wagner Blue Green.

Tom Wagner is the mastermind behind such tomato cultivars as Schimmeig Stoo and Green Zebra tomatoes. Essentially, Wagner has built a reputation around crossing heirloom tomatoes to create new cultivars. The offspring of these tomatoes are recognized as heirloom tomatoes by experts in the field.

Wagner’s tomatoes are bred using the old-fashioned method that makes use of multiple controlled crosses. The result is a clean seed that produces open-pollinated tomatoes and reproduces true to type.
