Thomasville Citrangequat
A unique and versatile citrus hybrid that is rarely encountered but prized by those in search of cold hardy citrus. The Thomasville Citrangequat is a complex hybrid of sweet orange, trifoliate orange and kumquat developed by the USDA in the early 1900s and named for Thomasville, Georgia. They can bloom repeatedly due to its kumquat parent and produce oblong fruits that can be used throughout the year. When they’re still green they have a flavor similar to a lime, when it colors up it tastes more like a lemon and has an edible peel like a kumquat, and if left to ripen over the winter can even taste like a sweet orange. Very vigorous, productive and easy to grow.
