Oishi-Wase Plum on Krymsk 1 (Spring 2027)


A beautiful and prolific Japanese plum.

This plum wins the prize for having the most delightful name. Pronounced "wishy-wasay" you will see it spelled Oushi-Wase, Ohishi-Wasi, and Oishiwase. This is a new introduction from Japan, a plum that is old and revered in both Japan and Korea. The midsized tree is not self-fertile, and it will need to be partnered with another Japanese plum. Like many plums, Oishi-Wase is susceptible to black knot, but we have found that pruning out galls in early spring provides sufficient control.

Oishi-Wase has a very beautiful, spreading habit and it produces prolific quantities of mid-sized, clingstone plums. If the tree is not pruned, overcropping will result in smaller, less flavorful fruit, but a well tended tree will produce deliciously sweet and juicy plums that are golden yellow, overlaid with red blush. Ripening begins very early and progresses in stages, so that a tree can be harvested over the course of several weeks. This is an excellent plum for the backyard and one of our favorites for stocking the farmstand.
