The tree has medium vigor and forms a dense crown with upright branches. The variety is self-fertile and serves as a good pollinator for other plum varieties.
The fruits are small, round, and dark blue with a waxy bloom. The flesh is yellow-green, fibrous, with a spicy taste; the stone does not separate completely. The variety matures in early September. The crop is prone to shedding and cracking in rainy weather.
