Abstract
The present invention relates to an interspecific tree and more particularly to a new and distinct variety broadly characterized by a medium to large size, vigorous, hardy, and productive tree. The present variety blooms in the early season, is self-unfruitful, requires cross pollination, but produces an abundance of pollen to entice bees. The fruit matures under the ecological conditions described during early July, with first picking on Jul. 1, 2007, and will hang on the tree for about fifteen more days. The fruit is uniformly medium to large in size, mostly red with orange yellow freckling in skin color, clingstone in type, oblate in shape, a red and yellow two-tone in flesh color, very firm and crisp in texture, and excellent in flavor.

1. A new and distinct variety of interspecific Prunus sp. tree, substantially as illustrated and described, that is similar to ‘Yummyrosa’ (U.S. Plant Pat. No. 13,476) plum by being self-unfruitful and by producing fruit that is medium in size, that is clingstone in type, that is mostly dark red in skin color, and that is a red and yellow two-tone in flesh color, but is distinguished therefrom by blooming earlier and producing fruit that is much firmer in texture, that is more oblate in shape, that is sweeter in flavor, and that matures about ten days later.
