Abstract
The present invention relates to a plum tree, Prunus salicina, and more particularly to a new and distinct variety broadly characterized by a medium size, vigorous, hardy, self-unfruitful, heavy blooming, pollen abundant, and usually productive tree that may be cross pollinized by ‘Blackamber’ (unpatented). The fruit matures under the ecological conditions described during mid August, with first picking on Aug. 11, 2002, but will hang on the tree for nearly twenty more days. The fruit is uniformly large in size, dark red in skin color, clingstone in type, yellow with some red bleeding in flesh color, very firm and crisp in texture, very good in flavor, and holds well in cold storage for more than thirty days. The variety was developed as a first generation cross using ‘Grand Rosa’ (U.S. Plant Pat. No. 1,756) plum as the selected seed parent and an undetermined plum as the pollen parent.

I claim: 1. A new and distinct variety of plum tree, substantially as illustrated and described, that is most similar to its seed parent, ‘Grand Rosa’ U.S. Plant Pat. No. 1,756), by being self-unfruitful and by producing plums that are globose to oblate in shape, mostly red in skin color, and yellow with some red bleeding in flesh color but is distinguished therefrom and an improvement thereon by producing plums that are clingstone instead of semi-freestone, that are smoother in skin surface, that are sweeter in flavor, that do not have a tendency to tip crack, and that mature about 3 weeks later.
