It needs a compatible hybrid plum nearby for consistent fruit set. Pollenizers for Underwood include Alderman, Pipestone, Hanska, and Gracious, Toka, Kuban Delight, Ptitsin #5, La Crescent, Superior, and other Asian–American hybrids. Native American plum and Prairie Red can work as pollenizers for these hybrid types as well.\u003c\/p\u003e\n\u003ch3\u003eCold Hardiness\u003c\/h3\u003e\n\u003cp\u003eWe have observed Underwood surviving -38F in Stevensville, MT from a 1\/13\/24 polar front without showing any signs of winter injury. St. Lawrence lists Underwood as hardy to -50F with occasional winter injury. Because we cannot verify this claim in our experience, we are conservatively saying Underwood is hardy to -40F.

We tried growing it after learning it was hardy to zone 5. I wouldn’t plant Santa Rosa nor any of our other Asian plums (except Taylor Apple Pear) any lower than zone 5. They do happen to like our hot summers and grow well, but the only thing is (as is the case we’ve found with all Asian plums in zone 5) they must be wrapped in burlap if you see the forecast call for below 0 temps before Dec. 1st (as is the case with other fruits like most of the sweet cherries and most peaches). Super tasty are these plums! Plant with Elephant Heart, Duarte, or Shiro for pollination.
