Russian origin. In Russia the Trifele varieties of tomatoes (of which there are several colors) are highly prized and command big prices. This short potato leaf plant yields prolific quantities of 6 oz. fruit that looks like a beautiful mahogany-colored Bartlett pear with greenish shoulders. Very tasty flesh with a meaty core that produces luscious fruit all summer long. A work of art sliced out on a plate and a wonderful flavor that possesses extraordinary rich and complex flavors. The Black Trifele is one of the blackest varieties available and is resistant to cracking.
