Were there not so many handsome, well-flavored plums of the Reine Claude group, Esperen might well be recommended to the amateur at least, for it is first class in appearance and quality. But the fruits are small and the tree-characters are not such that the variety can compete with the standard Reine Claude plums. Esperen was produced from seed in 1830 by Major Esperen of Malines, Belgium; it was first fruited in 1844, and was introduced in 1847 by Louis Van Houtte of Ghent, Belgium. It obtained the designation Drap d’Or from its close resemblance to that variety.
Tree large, vigorous, upright-spreading, productive; trunk stocky, rough; branches rough, with numerous, large, raised lenticels; branchlets brash; leaves flattened, two and one-half inches wide, five inches long, obovate or oval; margin serrate; petiole thick, tinged red, pubescent, with from two to five large, globose glands.
Fruit mid-season; about one and one-half inches in diameter, roundish-oval; cavity shallow, narrow, often lipped; color yellow streaked and mottled with green, overspread with thin bloom; skin thin, tender, rather sour; flesh yellow, tender, sweet, aromatic; of good quality; stone free, one inch by five-eighths inch in size, oval, with pitted surfaces; ventral suture blunt; dorsal suture wide, deep.
