PATENT OFFICE ROSE Application March 23, 1936, Serial No. 70,513

1 Claim.

The present invention relates to a new and distinct variety of Rose plant, having as its primary objective to further improve the yellow rose, including a reduction of the weaknesses inherent 5 in the Pernetiana race, reinforcement and purification of the color by elimination of foreign tints.

The various operations culminating in this invention started by pollinating Ophelia with Souvenir de Claudius Pernet. These two parents were selected because Ophelia was and still is one of the most artistic buds we have in roses and at the same time one of the healthiest plants. Souvenir de Claudius Pernet is the purest yellow color and the strongest yellow parent genetically. One seedling of this cross was selected, the pollen of which was put back into Ophelia and one of the progeny of this new cross became the rose now in commerce under the name of Mrs. Pierre S. du Pont.

Mrs. Pierre S. du Pont has all the attributes of a good garden rose as to plant, health of foliage and floriferousness but the individual flowers leave much to be desired in form, lasting quality, 25 clearness and purity of color. To correct these faults, I selected the pollen of Souvenir de Claudius Pernet which has an excellent form, color long lasting and of the purest yellow. I made this cross for several years in succession and in suffi- 30 cient quantity to raise a large number of seedlings. After a long process of elimination, three seedlings remained for extensive tests in various parts of Europe and America, and the rose herein 35 described was unanimously selected as the best of the three.

I may also add that my work toward a perfect yellow rose started in 1920 when the original cross of Ophelia and Souvenir de Claudius Pernet was made, and the present rose is the attainment of the objective. The rose has been asexually propagated for several years and comes uniformly true to form.
