Abstract
The present invention relates to an interspecific tree and more particularly to a new and distinct variety broadly characterized by a medium size, vigorous, hardy, and very productive tree. Being self-unfruitful, the present variety requires cross pollination from an apricot, interspecific, or plum that blooms during the late season. The present variety produces a very heavy bloom with an abundance of pollen to entice good bee activity to facilitate pollination. The fruit matures under the ecological conditions described during the last half of October, with first picking on Oct. 23, 2011. The fruit is uniformly medium in size, very dark red to purple in skin color, semi-clingstone in type, globose to oblate in shape, yellow in flesh color, firm in texture, and excellent in flavor.
Show the legal claimThe single numbered claim as granted — the legal text that defines what this patent covers.
I claim: 1. A new and distinct variety of interspecific Prunus sp. tree, substantially as illustrated and described, that is similar to its seed parent, ‘September Yummy’ (U.S. Plant Pat. No. 14,220) plum, by being self-unfruitful and by producing fruit that is semi-freestone in type, juicy, firm in texture, and mostly yellow in flesh color, but is distinguished therefrom by producing fruit that is darker red in skin color, somewhat smaller in size, oblate instead of globose in shape, sweeter in flavor, and that matures about forty days later.
