Kappa Cherry Plum was released by Cecil Patterson at the University of Saskatchewan in 1960. This compact Canadian cultivar bears heavy crops at a young age. The small fruit has dark blue black skin, yellow green flesh, and a sweet fruity flavour with mildly tart skin. It ripens in late August on the prairies and is used fresh or for jam and canning. Kappa needs a compatible cherry plum or Japanese plum for pollination.
Here's a comparison of the cherry plum cultivars we're growing.
