Description Inventor: Stephen M. Southwick, Davis, CA (US) The original tree of the new Prunus mahaleb cultivar of the present invention was discovered through detailed evaluation and selection while growing in a cultivated area at the Experimental Orchards at the University of California located at Davis, Calif., USA. The exact parentage of the new cultivar is unknown. The seeds used to form the planting where the discovery took place came from a random collection of wild Prunus mahaleb germplasm that had been collected from around the world. The large number of seedlings present in the planting were carefully studied and evaluated and a single plant possessing the combination of characteristics of the new cultivar of the present invention was selected and was preserved. Had this plant not been discovered and preserved, it would have been lost to man kind. Forms a tree that is intermediate in size and forms more fine wood when compared to the 'UCMH 56' and 'UCMH 59'.
