UNITED STATES PATENT OFFICE ROSE PLANT Paul Shamburger, Tyler, Tex.

Application February 19, 1951, Serial No. 211,616

1 Claim. 1,

The present invention relates to a new and distinct variety of rose plant, originated as a sport of the variety Floradora (unpatented), and dominantly distinguished therefrom by the distinctive pink color of its blooms. The new variety was discovered in a cultivated nursery row of Floradora plants growing on my nursery property near Tyler, in Smith County, Texas.

The parent variety is a bush rose of the polyantha class, and is notable for the imbricated arrangement of the petals of its flowers, by the long-lasting habit of the flowers both on the bush and as cut-flowers, and by their unique scarlet color eifect which is maintained to an extraordinary degree throughout the blooming season.

Of primary importance here, however, is the distinctly different, pink color of the flowers of the new variety. Aside from this color diiIerence, the new variety is generally similar to its parent Floradora" except for minor differences in its foliage. thorns and habit of growth which do not detract from the desirable and attractive qualities of the combination as a whole which are unique in a pink rose.

Asexual reproduction of the new variety by budding at Tyler, Texas, shows that the foregoing characteristics come true to form and are established and transmitted through succeeding propagations.

The accompanying drawing shows specimens of the flowers and foliage of the new variety in different stages of development.

The following is a detailed description of the new variety, with color terminology in accordance with Ridgways Color Standards and Nomenclature, except where general color terms of ordinary dictionary significance are obvious:
