The Apple Plum
It is difficult for the casual observer to believe at first that the plum here represented is not an apple, as it has the form, color, general appearance, and rare keeping qualities of the fruit that suggested its name. It is a remarkably free grower, having led to the comment that buds and grafts of this variety "would probably grow if fired among the trees from a shotgun."
