This is the original "blue" tomato released in 2012 by Dr. Jim Myers at Oregon State University. He used conventional breeding methods to get its dramatic purple color by drawing on a substance found in wild tomatoes from Peru and the Galapagos Islands. The substance is called anthocyanin, and it is a powerful antioxidant that protects us against disease and early ageing. Indigo Rose develops a dark purple skin wherever the fruit is exposed to direct sun, but it needs to ripen fully to develop good flavors. It is not ripe until the fruit softens, the bottom turns from green to red, and the flesh is deep red. Expect an abundance of these very beautiful 1 to 2 oz. deep purple fruits with rosy undersides and deep, brick red flesh. Indeterminate. 75 days.
