Application November 19, 1935, Serial No. 50,591

1 Claim.

The present discovery relates to a new and distinct variety of rose plant, having as its primary object the creation of a double Etoile de Hollande, for which a universal desire has long existed.

While the present seedling may be considered as an improvement of the same class as this known rose, it differs therefrom in important respects, in that the bloom is slightly darker in the average run, much fuller and with the same pronounced fragrance of R. centifolia, generally termed old rose perfume.

In respect to the habits of growth this new variety is much more vigorous and robust than Etoile de Hollande, and blooms more continuously without the prolonged periods of rest characteristic of Etoile de Hollande.

Everything considered, there is no other rose in commerce possessing the same general characteristics as the new variety, and as a garden rose, it meets with very great approval generally.

Asexual reproduction of this new Variety shows the characteristics to be fixed.
