Abstract
The present invention relates to an interspecific tree and more particularly to a medium size, vigorous, hardy, and productive tree. The present variety has a prolific bloom during the early to mid season, is self-unfruitful, but produces an abundance of pollen to entice bees to facilitate pollination. The fruit matures under the ecological conditions described during early July, with first picking on Jun. 30, 2007. The fruit is uniformly medium in size, blackish red in skin color, clingstone in type, globose to obovate in shape, dark red in flesh color, firm and crisp in texture, and outstanding in flavor.
