Ok. The Shiro plum is a new thing for me and my family. We were out about the state (a few different towns) visiting various farm stands when at one stand we saw the Shiro plum. My mother and I tried one (they said we could). I didn't like it, but she loved it and would like some more information on it. I have tried searching on line, but can't seem to find anything about the plum itself. Any input?????
