10 August 2026
The tree is vigorous, reaching a height of 3.5 to 5 meters. The crown has a pyramidal shape with steeply rising branches. The variety is self-fertile and characterized by a high degree of health, although fruit thinning is required during abundant fruiting.
Fruits are medium-sized with a weight of 25–34 grams, having an oval or egg-shaped form. The skin is dark blue with a waxy bloom, the flesh is yellow-green or yellow, juicy, with a spicy sweet taste. The stone separates well from the flesh. The fruits are versatile in use and suitable for transport.
The variety is considered mid-early and serves as a benchmark for determining the ripening dates of other plums. Harvesting takes place in the period from the end of July to August.
