Blue berries tomato is a small cherry variety. Very dark purple color, which means it’s super-rich in anthocyanins. Unripe, the fruits are a glowing amethyst purple. At maturity they turn deep red where the fruit was shaded; the areas that received intense sunshine are a purple so deep it’s almost black! The flavor is intensely fruity, and sugar-sweet. Plants are very productive, yielding all season in elongated clusters that look beautiful.
