The present invention relates to a plum tree and more particularly to a new and distinct variety broadly characterized by a large size, vigorous, hardy, and productive tree. Being self-unfruitful, the present variety requires cross pollination from another plum or interspecific tree that blooms during the mid to late season, such as ‘;September YUMMY®’; plum tree (U.S. Plant Pat. No. 14,220). The present variety's moderate blossom density and abundant pollen production entices strong bee activity to facilitate pollination. The fruit matures under the ecological conditions described during mid to late September, with first picking on Sep. 20, 2018. The fruit is uniform, large in size, very dark red in skin color, clingstone in type, mostly yellow in flesh color, firm in texture, juicy, and outstanding in flavor.
