The tree is medium-sized, forming a spherical crown; shoots are thin with slight pubescence. Leaves are large, leathery, oval in shape, double-serrated at the edges, with strong pubescence on the underside. Fruits are round-oval, weighing 30–70 g, with thin greenish-yellow skin and a whitish bloom. The flesh is greenish-yellow, firm and juicy, and the pit separates easily.
The variety is of mid-season maturity; fruits ripen in late August or early September. Fruiting begins in the 3rd–4th year, but a full yield is produced from 7–8 years, and can be irregular. The plant possesses high winter hardiness down to -28°C and drought tolerance; however, the fruits are susceptible to fruit rot under conditions of high humidity.
The variety is partially self-fertile and requires the presence of pollinators blooming at similar times. The intended use of the fruits is universal: they are suitable both for fresh consumption and for all types of industrial processing and drying.
