World’s Darkest Tomato–The darkest tomato we know of! A dark, meaty, very rich-fleshed tomato with extreme anthocyanin expression (same antioxidant in blueberries and blackberries). So dark that some tomatoes turn solid blue-black on the skin. Deep red flesh is among the best tasting of all tomatoes. Rich, smooth and savory with earthy tones. Hangs well on the vine and stores very well, and the flavor improves with room-temperature storage. Mid-late season. Indeterminate.
