Oishi-Wase Plum on Krymsk 1 (Spring 2025)
A newly introduced Japanese plum.
This plum wins the prize for having the most fun name. Pronounced "wishy-washy" 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.
The fruit is large and golden yellow, overlaid with red blush. This is a clingstone plum that ripens very early.
