The variety was obtained by crossing the varieties Agen and Zarja. The tree has a dense canopy and moderate vigor. The variety is partially self-fertile; for increased yields, pollinators Ave, Polli viljakas, and Viktoria are recommended.
The fruits ripen in early September. They are small or medium-sized, have an oval or egg-shaped form, and dark purple skin with a heavy waxy bloom. The fruit flesh is greenish-yellow, soft, with a sweet-and-sour taste; the stone separates well.
The variety is relatively winter hardy and possesses good resistance to diseases.
