The Apple is a conspicuous plum; its shape, color, size, flavor; its firm, blood-red flesh and long-keeping quality, all distinguish it. Even the tree is marked with its robust growth, flat-topped head, peculiar, light brown bark, handsome foliage and wood that can be propagated from cuttings with surprising ease. It is difficult to predict the future of this interesting plum, but probably it will remain for most part a curiosity. Its peculiar flavor is not pleasant at first taste and it is doubtful if many will learn to like it. Unpalatability is the defect of the variety which will most often be counted against it. In general the Apple is inferior for dessert or kitchen to the Satsuma, itself none too good, which it most nearly resembles of all plums. In the Station collection tree and fruit are quite susceptible to both fungus and insect pests and the fruits ripen unevenly. The fruit of the variety keeps and ships remarkably well and these qualities may be its saving grace, both so well developed as to make it valuable for breeding purposes when these characters are desired. In his catalog for 1898 Burbank announces the Apple as a new plum and says, “Among the welcome surprises found three years ago among a lot of some twenty-five thousand plum seedlings was this one, bearing a cruel load of enormous plums when only two years old.... It was at once named Apple from the very close resemblance in form, color general appearance, and rare keeping qualities.... Its parentage is not known, except that it is a second generation seedling from cross-bred seedlings, and no doubt Satsuma and probably Robinson are in its line of ancestry.” Satsuma characters are readily detected in tree and fruit and especially its hard, red flesh, but in no way is its descent from Robinson apparent. Tree of medium size, flat-topped, spreading, dense-topped, slow-growing, semi-hardy, productive; branches rough and thorny, with numerous fruit-spurs, dark ash-gray, reddish and with numerous lenticels; branchlets often with a rosette of flower-buds on the apex of the shoots, slender, with short internodes, greenish-red changing to dark brown, glossy, glabrous, with numerous, conspicuous, large, raised lenticels; leaf-buds small, short, obtuse, plump, appressed. Leaves folded upward, obovate or oblanceolate, one and one-quarter inches wide, three and three-quarters inches long, thin, leathery; upper surface purplish-red late in the season, glossy, glabrous, with grooved midrib; lower surface light green, pubescent at the base of the veins; apex acutely pointed, base cuneate, margin finely and doubly crenate and with small amber glands; petiole five-eighths inch long, pubescent, red along one side, with from three to ten large, conspicuous, reniform, red or yellowish glands on the stalk.
