Prunus salicina 'Shiro'
plum 'Shiro'
A Japanese plum producing medium size fruit with yellow skin and flesh. For warm sheltered sites only. The white, early spring blossom is prone to frost damage and protection is usually needed. It may set some fruit on its own, but it benefits significantly from cross-pollination with another Japanese plum to set good crops. Cropping season: July
