10 August 2026
The tree grows vigorously at a young age, forming a broad pyramidal or bushy crown that requires regular pruning. The variety is winter-hardy and partially self-fertile; planting pollinator varieties is recommended to improve yields.
Fruits are medium-sized, oval or oblong in shape, with blue-violet skin and a lilac waxy bloom. The flesh is yellowish-green, firm, juicy, and has a sweet-and-sour taste; the stone separates well from the flesh.
The variety is characterized by high and regular yields, although it may be prone to biennial bearing. It possesses tolerance to plum pox virus, but may be susceptible to rot in wet years.
