UNITED STATES PATENT OFFICE ROSE PLANT Application November 9, 1951, Serial No. 255,604

The present invention relates to a new and distinct variety of rose plant of the hybrid polyantha class, originated by me by crossing the hybrid polyantha variety Baby Chateau (unpatented) X the hybrid tea variety Red Delicious (Plant Patent No. 620) As the result of this cross, I have produced an improved variety which, though it is primarily adapted for use as an outdoor rose and excels in this class, is also useful for forcing under glass.

The primary objective in making the aforementioned cross, was to produce a new variety of rose of the polyantha type, with flowers of a color comparable to the parent variety Red Delicious, but having a stronger neck than the typical weak neck characteristics of this parent. This objective was fully achieved, as evidenced by the fact that the color of the flowers of my new variety is more nearly like Red Delicious," but is a somewhat brighter red than the color of the flowers of either parent.

The parent variety Red Delicious is primarily a greenhouse forcing rose, and normally bears flowers singly to a stem, instead of in clusters. While the brilliant red color of this parent variety was very outstanding, it has not been too successful commercially by reason of the weakness of the neck, which has been eliminated in my new variety. In addition to the foregoing improved features of this new variety, it is a more vigorous grower than the variety Baby Chateau, with the result that the plants of the new variety grow taller, and the flowers keep better than those of Baby Chateau.

Briefly stated, the principal characteristics of this new variety which distinguish it from its parents, as well as from all other varieties heretofore known in commerce, are the abundance and the extra bright color of its flowers, combined with the exceptional good-keeping qualities thereof.

Asexual reproduction of my new variety by cuttings, grafting and budding at Richmond, Indiana, shows that the foregoing characteristics come true to form and are established and transmitted through succeeding propagations.

The accompanying drawing shows specimen flowers of the new variety in various stages of development from tight bud to fully open, as well as upper and lower surfaces of typical foliage specimens, and also a short section of a specimen stem with a typical thorn arrangement.

The following is a detailed description of my new variety, with color terminology in accordance with Wilsons Horticultural Colour Chart, except 1 Claim.
