Blaue Krieche is a traditional local form, not a modern breeding achievement. In agronomic literature, this type is often classified in the group Prunus domestica avenaria, and its ripening period historically coincides with the oat harvest.
The fruits of this plant are small, oval-shaped, and have a blue-black color. The trees are characterized as vigorous, with a dense canopy and early flowering.
In various sources, this name may refer to local forms or types of damson Prunus insititia or wild-growing plum forms. Information regarding disease resistance and specific agronomic practices is limited to historical descriptions.
