Hello. I have both Teas Weeping mulberry and a Persian mulberry. BOTH BERRIES ARE VERY TASTY, with the Persian berry having a much bolder flavor, with a more sweet/tart complex taste. The weeping tree fruits about a month or two before the Persian. So far, my weeping tree has produced far more fruit. Both are about 4 years old. I suspect the Persian will eventually produce more fruit as it gets bigger, but that may take a few more years. The fruiting season of both are approximately the same as far as length of season, with the Weeping producing edible fruit around May 1st, and the Persian about a month to six weeks later. The Pendula weeping mulberry tree is also a beautifully ornate and original looking tree. Plant it where it can be viewed year round. I like to prune it into a mushroom shape in winter. It looks awesome! I am also training it to be a natural "fort", where one can hide inside the tree, and also pick fruit from within. It is my favorite tree of all that I have. Alba, Rubra, and Nigra refer to the hue of the bark, not the color of the fruit. Hope that helps if it's not too late (you may have already planted).
