Plum tree &#34;Santa Rosa-Two&#34;
BACKGROUND OF THE NEW VARIETY 
     The present invention relates to a plum tree, known as the &#34;Santa Rosa-Two&#34;, and more particularly to such a plum tree which bears large, uniform, dark Purplish-Red fruit which ripens approximately five days before the &#34;Santa Rosa&#34; (unpatented) Plum Tree and which is further distinguished from the Santa Rosa Plum Tree by bearing fruit whose flesh is firm, Amber in color, and lightly streaked with Red near the pit cavity. The Santa Rosa-Two Plum Tree is further characterized by large, deep green leaves. In addition, the tree has spur leaves which are characteristically narrower than the leaves that are produced on the shoots. 
     In a continual effort to upgrade the quality of his fruit, the applicant is constantly on the alert to locate any new varieties that may appear on the seedling fruit trees of any of his several farms. In his labors to produce new varieties, the applicant has germinated thousands of seedlings and has grown the resultant seedlings to maturity and carefully studied the characteristics of the progeny. The present variety of plum tree resulted from this procedure. 
     The plum tree of the present invention is noteworthy in ripening approximately five days before the Santa Rosa Plum Tree, i.e., June 23, in 1983, a very popular variety. 
     ORIGIN 
     The present variety of plum tree was a seedling which resulted from the germination by the applicant of numerous seeds at the inventor&#39;s ranch located at the corner of Kings Canyon Road and Fowler Avenue, Fresno, County of Fresno, State of California, in 1977. The seedling was of unknown origin inasmuch as the present variety was a chance seedling, its origin or cross is unknown, although it was known by the applicant in the sense that he knew that the seedling was germinated, was asexually reproduced, and was tested at his designated ranch. The subject variety was observed for several years prior to recognition of its desirable characteristics. The applicant asexually reproduced the subject plum tree by grafting scions thereof onto various standing plum trees located in the same orchard where the seedling had developed. This first propagation which occurred in 1980, resulted in progeny being produced that were found to possess the same distinctive characteristics as the original seedling. The grafted trees were grown on the applicant&#39;s ranch designated above. 
    
    
     BRIEF DESCRIPTION OF THE DRAWING 
     The accompanying drawing is a color photograph of a characteristic twig bearing typical leaves, a cluster of two plums showing their external coloration sufficiently mature for harvesting and shipment, three mature plums of the color when matured on the trees, a plum halved transversely of the suture plane to illustrate the flesh coloration and four stones, all of the subject variety.

     Although the new variety of plum tree possesses the described characteristics as a result of the growing conditions in Fresno County, Calif., in the central part of the San Joaquin Valley, it is to be understood that variations of the usual magnitude in characteristics incident to growing conditions, fertilization, pruning and pest control are to be expected.
