Plum - Mt ROYAL
The Mt ROYAL blue plum was found growing wild on the mountain in Montreal and quickly spread throughout Quebec because of its sweet and tasty flesh. This European plum must have been brought over as a seed by an early settler and has now spread across Canada and USA. Great plum for fresh eating and processing into jams, etc. Tree stays dwarf ( 8 ft) and has Zone 4 hardiness. Flowers are self-fertile so great back yard tree for plum lovers. Only drawback is that all European plums, like Mt Royal, are now getting black knot disease in Canada which causes the Mt Royal trees to slowly lose their productivity as the tree ages. This disease does not affect the fruit so if the tree does get infected you may still get many years of great fruit before the tree dies out.
