10 August 2026
The tree is medium-growing or vigorous, forming a wide-rounded, spreading, medium-dense canopy. The variety is self-fertile or partially self-fertile. Minimal canopy intervention is recommended during cultivation, as heavy pruning provokes shoot thickening and yield reduction.
Fruits are medium or large in size, weighing about 20 g, have an elongated shape and dark blue skin with a waxy bloom. The flesh is greenish-yellow, firm, moderately juicy, with a wine aroma; the stone separates well. The harvest ripens at the turn of August and September.
The variety possesses high frost resistance and adapts well to various climatic conditions. It exhibits moderate resistance (tolerance) to Plum pox virus and medium resistance to moniliosis. The fruits are suitable for fresh consumption, drying, canning, and distillate production.
