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 very 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 IV’ interspecific tree (U.S. Plant Pat. No. 16,461). The present varietys abundance of blossoms and pollen entices strong bee activity to facilitate pollination. The fruit matures under the ecological conditions described during the first week of October, with first picking on Oct. 1, 2015. The fruit is uniform, very large in size, nearly full red in skin color, freestone in type, pure yellow in flesh color, firm in texture, juicy, and very good in flavor.
