This plum is the highest ranked of the AU series of plums in disease resistance to bacterial spot, black knot, scald and brown rot. With all the flavorful attributes of Santa Rosa, these firm dark red fruit have a saffron yellow flesh that is juicy with an excellent flavor. Great for fresh eating, cooking and canning. Trees are vigorous and productive. Ripens early August. Growing beautifully in Ithaca, so hardy at least north to zone 5B. (700 chill hours.) SELF FRUITFUL.
