Recent variety created by Anna Jankowski, aka "Kozula", famous Polish breeder.

Only the colour seems to be stabilised, but the shape is notoriously variable.

The fruit weighs between 100 and 200 grams and has a dark purple, almost black skin with metallic green stripes. The shape varies from a pointed ovoid plum with a small, more or less developed nipple at the apical end to a flattened fruit with or without a rib on the upper half.

Absolutely delicious, rich and aromatic flavour.
