85 days. This curious and striking tomato is guaranteed to turn heads as well as satisfy appetites. Its name is simply Italian for oxheart, although this selection(Riviera) is an exotic twist on the oxheart tomato type. These big tomatoes have a bottom-heavy shape reminiscent of a pouch with a gathered top. They measure 3 1/2 inches wide and 4 inches long and weigh in just under 1/2 pound each. Cuore di Bue is one of the tastiest saucing types with dense flesh and lustrous, orangey-red skin. Indeterminate.
