Kryptonite is a truly exotic-looking tomato that blends the deep blue of anthocyanin with green and yellow flecks and striping. As its appearance may imply it is appropriately tangy in taste. As with other varieties with anthocyanin the fruit are extra durable and have an extended shelf life and average 2-4 oz. Kryptonite is quite productive, and the plants are indeterminate. They have semi-late maturation cycle and grow on the shorter side; averaging about 3-5 feet in height. It is also not uncommon for the leaves to be somewhat curly.  Text from >Wild Boar Farms.
