From the Vineland (Ontario) breeding program; Imperial Epineuse x Grand Duke. Ripens late in Fellenburg (Italian Prune) season ( = late midseason), but much larger and much better flavor. Dark purple skin, greenish-yellow flesh. Very sweet, freestone when ripe. Tree is very productive, susceptible to black knot, but resistant to bacterial spot. Partially self fertile, though a pollenizer is still recommended.
