These are absolutely delicious, juicy plums. My tree is 5 years old and this is the 2nd year producing. Late frost can be a problem. I planted it near a Hollywood plum, then read that they don't necessarily cross pollinate, so now I'm adding a Methley plum. I also read that they self pollinate, and that they don't self pollinate. Even so, this year's crop promises to be my best so far. Should not be your only plum tree, but is worth adding to a mixed backyard orchard.

Shiro plums are not self-fertile, or only marginally so. The information on that aspect, as well as a correct cross pollinator, is anything but consistent. None the less, it is so WONDERFUL when you do get some fruit from it!!!!!! Wear a bib or lean forward to eat it - as it will explode with its juiciness!!

This is my absolute favorite among the plums available today. Years ago we had a big yellow freestone plum that was better, but the name has been lost over the years and I never been able to find a cultivar that matched it. Shiro is a yellow clingstone but absolutely delicious. The tree grows rapidly to to the size of a peach tree. It does flower early and quite often the crop succumbs to late frost, but when you do get a crop its worth it. The trees are not long lasting so plan on replacing every 10-12 years.
