Variety description

10 August 2026

The variety is ultra-early; fruits ripen in late May or early June. The tree grows with moderate vigor, reaching a height of 3.5–4.5 meters, and forms an almost spherical, moderately dense crown.

Fruits are medium-sized, approximately 4.5–5.5 g, and heart-shaped. Upon full maturity, the skin becomes dark red, almost black. The flesh is soft, juicy, with a sweet or slightly sweet-and-sour taste.

The variety is self-incompatible and requires the presence of pollinators that bloom at the same time. The plant has high winter hardiness and resistance to diseases and temperature fluctuations.
