Plum tree named `Summer Treat`

Abstract

A plum tree which is of medium to large size, open density, vigorous, upright to spreading-upright, foliated with medium size, obovate and linear, vigorous upright shoots having coarsely crenate margins, mostly globose and occasionally reniform glands which are very small in size, and the stipules are small and very thin with a small percentage remaining on the tree late into the season, blooms abundantly in mid-season with a medium size bud which is conical and quite plump in shape and remaining slightly cupped inwards even at full expansion, white medium flowers, and a regular productive bearer of medium to large, uniform, symmetrically formed, very late ripening clingstone fruit having deep mahogany to a lighter red apple color skin with a range of shades in between, and amber yellow to darker amber flesh, and red pigmentation is present under the skin surface and sometimes deeper. The fruit ripens substantially after the last commercial variety presently grown and has an unusually long harvest season with fruit remaining on the tree in good condition until early September.

I claim: 
     
       1. A new and distinct very late ripening variety of a clingstone plum tree having flesh of the amber yellow variety and substantially as herein shown and described, having firm, crisp flesh texture, the fruit having a sweet, rich flavor, being of medium to large size, deep mahogany to a lighter apple red in color with a range of shades in between, and by having a desirable symmetrical shape, where the plum ripens substantially after other existing commercial varieties, typically in mid to late July and has an unusually long harvest season with fruit remaining on the tree until early September.
