Shiro Plum on Guardian® (Spring 2022)


A sweet, yellow, early-season plum.

Adaptable to a broad range of climates, this is one of the most consistently productive Japanese plums in western New York, and it performs very well on the West Coast. Shiro grows on a medium-sized, vigorous, hardy, and long-lived tree that is somewhat susceptible to brown rot but resistant to black knot. This variety is partially self-fertile but it should be planted with another early-blooming Japanese plum for optimal cropping. Recommended partners include Methley, Vanier, Vampire, and Burbank. Studies suggest that Early Golden will not pollinate Shiro.

The medium sized fruit is a pretty golden-yellow, sometimes with a delicate pink blush, and slightly oval. The juicy flesh is a light, translucent yellow and has a tender, melting texture. The flavor is sweet and mild with a slightly tart skin. Shiro doesn't ship well, but it is a great plum for home gardens, farmstands, and U-pick orchards. Ripening early July in Geneva, NY (about ten days after Early Golden), Shiro is a very attractive early-season plum with broad appeal.

Shiro was developed by Luther Burbank, who also gave us Santa Rosa, Burbank, Beauty, and Wickson plums. Shiro was reported by Burbank to be a progeny of Robinson (Prunus munsoniana), Myrobalan (Prunus cerasifera), and Wickson (a cross of Prunus triflora and Prunus simonii) from a Wickson seed. It was introduced in 1899.
