Ostheim cherry
The Ostheim cherry is a variety of sour cherry (Prunus cerasus) that ripens relatively early. There are also individual named high-performance clones that were selected from this genetically more diverse mixture of forms, most famously "Reinhardts Ostheimer", "Naumburger Ostheimer" and "Kochs verbesserte Ostheimer Weichsel". The variety is recommended for fresh eating, but also for processing and has also been used as graft rootstock.
