From Johnny's Seeds: Dramatic color contrast. Purple Bumble Bee is an eye-catching combination of the dusky purple seen in heirloom tomatoes and metallic green striping. Sweet flavor and meaty texture provide a nice accent to any salad. Like all the Artisan™ tomatoes, Purple Bumble Bee was bred with high vigor to perform under tough conditions. 20-25 gm. fruits. Indeterminate.
