The present invention relates to a plum tree and more particularly to a new and distinct variety broadly characterized by a medium 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 ‘;Plumsweet X’; interspecific tree (U.S. Plant Pat. No. 19,528). The present variety's abundance of blossoms and moderate pollen production entices strong bee activity to facilitate pollination. The fruit matures under the ecological conditions described during the second week of September, with first picking on Sep. 13, 2018. The fruit is uniform, medium in size, almost full red in skin color, clingstone in type, red to pink in flesh color, firm in texture, juicy, very sweet and excellent in flavor.
