Solanum glaucescens - Cuatomate - A wild an almost unknown edible fruit found in the Mixtec region of Mexico, in and around Oaxaca. A tomato relative (but not a tomato), it yields greenish-white fruits that eventually ripen to orange, with deep red pulp that is highly prized locally, yet little known elsewhere. A perennial, though capable of fruit production after 1-2 years. Sources suggest the fruits have commercial potential. Climate requirements are not known, though the plant is likely not frosted tolerant.
