Changsha Mandarin Citrus Tree
Likely the most cold hardy of any mandarin, Changsha is a very old Chinese cultivar that has been widely tested for its cold hardiness in various zone 8 climates and is typically hardy to at least 10 F. Fruits are very tasty but need to be picked just as they ripen. If left to hang on the tree for a long time they become pretty flavorless and watery. Changsha has been used to hybridize many new cold hardy citrus and the possibilities for new citrus with Changsha in their parentage is very promising and exciting.
