Non-GMO Black From Tula Heirloom Tomato Seeds from True Leaf Market produce 4" to 5" fruit with a sweet and salty to rich and smoky flavor, depending on the growing conditions. As an indeterminate tomato variety, the Black From Tula tomato height will be as tall as the season permits, and it's a good idea to stake or use a tomato cage for Black From Tula tomato plants to keep the heavy fruit off the ground and to promote good air circulation around the plant. The largest of the black tomato varieties, Black From Tula tomato plants produce well in hot climates. These heirloom tomato seeds are produced by a small, family-run seed company called Mountain Valley Seed Co. 75 to 85 days to maturity.
