The tree is moderately vigorous, with a pyramidal or broad-pyramidal crown of medium density. The variety enters bearing early and is distinguished by regular high yield, which requires regular pruning to renew fruit-bearing branches.
Fruits weighing 26–30 g (up to 40 g), oval or elongated in shape, dark blue in color with a waxy bloom. The flesh is yellow, firm and juicy, with good stone separation. The variety has good transportability, is relatively winter hardy, but is sensitive to fungal diseases and moderately susceptible to the plum pox virus.
Maturity group is medium-early or medium, fruits usually reach ripeness at the end of August. The variety is self-fertile, which allows it to bear fruit without additional pollinators.
