Abstract
The present invention relates to a new and distinct variety of peach tree, Prunus persica , broadly characterized by a medium size, moderately vigorous, hardy, self-fertile, productive and regular bearing tree. The variety blooms during the mid to late blooming season and requires about 600 chilling hours. The fruit matures under the ecological conditions described in the last half of August, with first picking on Aug. 20, 2013. The fruit is uniform, very large in size, globose in shape, freestone in type, firm and melting in texture, white in flesh color, mostly red in skin color, and a tasty balance of light acid and sugar in flavor.

We claim: 1. A new and distinct variety of peach tree, substantially as illustrated and described, that is most similar to ‘Glacier Princess’ peach (U.S. Plant Pat. No. 23,867) by having a medium vigorous tree with large blossoms, by having reniform leaf glands, by being self-fertile, by having a bitter tasting kernel, and by producing white flesh freestone peaches that are very large in size, mostly red in skin color, globose in shape, firm in texture, and good in flavor, but is distinguished therefrom by blooming about ten days later, by requiring more chilling hours, and by producing fruit that matures about fifteen days earlier.
