Grow Heirloom Tomatoes - Druzba Tomato Seeds. Druzba, Bulgarian for friendship, produces season-long indeterminate harvests of 6-8 oz smooth, blemish-free, deep red tomatoes. Excellent tomato taste with just the right amount of tart. Perfect for hamburgers and sandwiches as Druzba Tomatoes are much larger than other heirloom beefsteaks.
