J. B. Rue is a plum described in northern plains trial literature as a large, attractive, good quality variety. It was distributed by Prof. Budd and linked to Rue of Pottawattamie County, Iowa. A South Dakota bulletin says it was received from the Iowa Experiment Station in 1898, placing it in the late nineteenth century exchange and testing of Midwestern plums. [S1]
The fruit is described as very large, round, and deep red, with sweet, solid flesh, a rather tough skin like Wolf, and a rather large pit. It ripens evenly around September 7 to 10 and is described as a very good keeper. The same source also calls it very attractive and of good quality. [S1]
The tree is described as large, strong, and open in habit, and it was considered a good bearer. The bulletin adds that it needs pruning to make a more compact tree. [S1]
Hardiness is not stated directly on the cited page, but J. B. Rue was being evaluated in South Dakota and was considered productive there. A 1903 photographic plate in the same bulletin also includes J. B. Rue under the heading "Native Plums," which may show how the station grouped it visually. [S1]
Its broader identity remains uncertain. One part of the bulletin includes J. B. Rue among the cultivar descriptions, while the plate groups it with native plums. The available evidence does not establish a clear species placement or parentage. What stands out is its combination of very large red fruit, sweet solid flesh, even ripening, and keeping quality. [S1]
