Cheney is of little value except towards the northern limits of fruit culture in America where, because of its great hardiness, it is a most desirable fruit-plant. Of the varieties illustrated and described among the leading plums in this text, Cheney is the sole representative of _Prunus nigra_, the wild plum of Canada and of northern United States. The accompanying description shows that while the fruit of this variety is not such as to recommend it where other species can be grown, the tree has some characters most desirable wherever plums are grown—hardiness, vigor, productiveness and good form—so that this variety might well be used in breeding plums. The trees are very ornamental whether in flower, full leaf or fruit, but especially when in full bloom as they bear a great profusion of large white flowers which change to a pleasing pink before falling. This plum, according to a letter from the discoverer, E. Markle, of La Crosse, Wisconsin, was found in the brush on a ridge, in Vernon County, Wisconsin, about twenty-five or thirty years ago. Mr. Markle thought it must have sprung from a seed dropped by an early voyager of the Mississippi River as there were no similar plums in the region. Noting its good qualities Mr. Markle introduced the variety, the date of introduction being about 1887. The American Pomological Society added Cheney to its fruit catalog list in 1897, where, however, it remained but two years. Tree large, vigorous, spreading, dense-topped, hardy, productive, bears early, somewhat susceptible to disease; branches numerous, dark brownish-gray, very thorny, with large lenticels; branchlets long, with long internodes, greenish-red changing to dull reddish-brown, dull, thickly pubescent early in the season, the pubescence decreasing at maturity, with raised lenticels which are variable in size; leaf-buds smallish, short, conical, free.
