Indigo Blue Berries is as appealing to the palate and eye as its name implies. Indeterminate plants produce trusses of the delightfully delectable little, 1-2 ounce, cherry tomatoes. Taste testers blissfully describe the flavor as sparkling. The green fruit quickly develop purple tops and crimson bottoms, ripening to a midnight black tone with deep, maroon-colored bottoms. Not only are they extraordinarily colorful and tasty; they are extra nutritious. Developed with traditional breeding techniques, the fruit of these unusual varieties contain high levels of anthocyanin, a naturally occurring antioxidant found in blueberries, and is reported to combat disease. Anthocyanin reveals itself in the vibrant indigo pigmentation of the fruits. Each of these varieties has unique characteristics, and are all stunningly beautiful. For the best flavor and texture, harvest when the colors have deepened and the fruit is soft to the touch.
