The tree of this variety is vigorous, reaching a height and width of about 6 meters, with a lush crown. The variety is mid-late ripening, with the harvest in Central European conditions gathered in the second half of September. Yield is high.
Fruits are large, oval or elliptical in shape. The skin at maturity is dark blue with a bloom; the flesh is yellow-orange, juicy, aromatic, and has a high sugar content. The pit separates from the flesh. Fruits are suitable for both fresh consumption and processing.
The variety is self-fertile or partially self-fertile; the presence of pollinators helps improve yield and increase fruit size. Susceptibility to Plum pox virus is noted. Used in breeding as a parental form.
