Sultan is a Japanese plum with large, purple-fleshed fruit of very fine quality. A Northwest Nursery catalog lists it in the Hansen hybrid plum and cherry section and names Sultan as one parent of Sapa. [S1]
The source gives no breeder, release date, origin, tree description, ripening season, storage behavior, or disease notes for Sultan. In this record, Sultan is mainly important as a named Japanese plum parent in Hansen hybrid material, especially for Sapa. [S1]
The catalog page concerns hardy fruit culture in North Dakota and nearby prairie regions, but it does not state Sultan's own winter hardiness. Any hardiness claim for Sultan remains uncertain unless another source supports it. [S1]
