Abstract
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.
Show the legal claimThe single numbered claim as granted — the legal text that defines what this patent covers.
We claim: 1. A new and distinct variety of plum tree, prunus salicina , substantially as illustrated and described, that is most similar to ‘Plumsweet V’ (U.S. Plant Pat. No. 16,369) interspecific tree, by having a medium size tree, by being self-unfruitful, by blooming in the mid season, by being productive, and by producing fruit that has mostly red skin with freckles, that is medium in size, that is firm in texture, that is clingstone in type, and that is sweet in flavor, but is distinguished therefrom by producing fruit that is red instead of yellow in flesh color, that is heart shaped instead of oblate, and that matures about eighteen days later.
