We claim: 1. A new and distinct variety of plum tree, substantially as illustrated and described, characterized by its large size, vigorous, upright growth and being a regular and productive bearer of medium to large, yellow flesh, freestone fruit, having a good balance between acid and sugar to produce good flavor and eating quality; the fruit is further characterized by its firmness which facilitates its good handling and shipping qualities, the ability to remain firm on the tree 6 to 7 days after shipping ripe and in comparison to Casselman Plum (non-patented), the new variety has heavier production of larger size fruit with a greater degree of attractive red skin color and matures approximately 5 days earlier.
