These three mulberries are probably the same accession propagated under 3 different names. Saharanpur Local mulberry came to my garden directly from USDA. Australian Green was donated by a friend, and Pakistan White came from a CRFG exchange. I do not see any differences in the fruit flavor, shape, or the tree size. The leaf shapes are identical too.
These are very fast-growing large trees that will require pruning. The fruits are long, very sweet, with no acidity.
