Kelsey is distinguished as the largest, the latest and the tenderest to cold of all Triflora plums in America. The variety is not much hardier than the fig and cannot be safely planted north of Washington and Baltimore. The tree is vigorous, well formed and productive, having for its worst fault susceptibility to shot-hole fungus. The plums are large, very attractive in color and the flesh is firm, the plums being well fitted for shipping, with a rich, pleasant, aromatic flavor making the fruit very good in quality. In the South both curculio and brown-rot attack the fruits rather badly. It is unfortunate that this plum cannot be grown in this latitude.
Kelsey, the first of the Triflora plums introduced into America, was brought into the country by a Mr. Hough of Vacaville, California, in 1870, through the United States consul in Japan. John Kelsey of Berkeley, California, obtained trees from Hough and propagated it in his nursery to a limited extent. The first fruit was shown by Kelsey in 1877, though fruit is said to have been produced in 1876. In 1883, W. P. Hammon and Company, Oakland, California, secured stock of this plum from the heirs of Mr. Kelsey and the following year extensive sales were made. The plum was named in honor of the man who did most to bring it before the public. The American Pomological Society added the Kelsey to its fruit catalog list in 1889. The following description is compiled.
Tree vigorous, upright, vasiform, tender, productive, an early and regular bearer; leaves somewhat scant, small, lanceolate, narrow; blooming season early; fruit very late, season long; keeps and ships unusually well; large, cordate, conical, halves unequal; suture variable in depth; apex pointed; color rather unattractive yellow, tinged and splashed with red, often overspread with purple, with attractive bloom, more or less marked with conspicuous dots; stem sometimes adhering poorly to the fruit; skin tender; flesh delicate yellow, juicy, firm and meaty, rich, pleasant, aromatic; good to very good; stone clinging unless well ripened, small, in an irregular cavity larger than the pit.
