ActivePrunus domestica L. · European plum

10 August 2026
The tree is characterized by vigorous or medium growth and forms a large, wide spreading crown of medium density. The variety is self-sterile and requires pollinator varieties to produce a crop. Fruits ripen in mid-to-late August, have a spherical, slightly flattened shape and a weight of 21–40 g.
The fruit skin is greenish-yellow, sometimes with reddish dots; the flesh is yellow-green with a distinct aroma. The stone separates well from the flesh at the stage of full maturity. Fruits are prone to cracking in rainy weather and premature shedding under unfavorable soil conditions.
The variety is resistant to plum pox virus, but susceptible to Monilinia and shot-hole disease. The fruits are intended primarily for fresh consumption, and are also used for making compotes, jams, jellies, drying, and the production of distillates. Due to the thin skin, the variety does not tolerate transportation well.
