10 August 2026
The variety forms a tree with medium-vigorous to vigorous growth. Fruits are medium-sized, egg-shaped or spherical, colored blue-violet with a waxy bloom. The flesh is greenish-yellow, juicy, sweet, with possible slight astringency, while the stone separates poorly.
Fruit ripening occurs during the period from the second half of September to the first half of October. The variety is moderately resistant to Plum pox virus, but is susceptible to Monilinia and pest infestation. The trees are demanding of heat and fertile moist soils; historically, the variety was used as a rootstock for stone fruit crops.
