10 August 2026
The tree of this variety is vigorous, forming a wide, spreading crown of medium density with sprawling branches. The variety is self-sterile and requires the presence of pollinator varieties. The wood of the tree is characterized by brittleness, which can cause branches to break in strong winds.
The fruits have a round or slightly conical shape and an average weight of about 32 grams. The skin of the fruit is thin, dark blue, and covered with a dense, whitish bloom. The flesh is greenish-yellow, juicy, and contains fine veins. The pit is rather large and separates well from the flesh.
The variety has a universal purpose; the fruits are suitable for fresh consumption and for various types of processing. The variety itself is often used as a pollinator for other plum varieties.
