ROSE PLANT Filed Aug. 9, 1955 United States Patent O ROSE PLANT Gerrit de Ruiter, Hazerswoude, Netherlands, assignor to llgenfritz Nurseries, Inc., Monroe, Mich., a corporation of Michigan Application August 9, 1955, Serial No. 527,433

1 Claim. (Cl. 47-61) The present invention relates to a new and distinct variety of rose plant of the hybrid tea class, which was originated by me by crossing an unnamed and unpatented seedling derived from Orange Triumph (unpatented) X Golden Rapture which is known in Europe as Geheimrat Duisberg (unpatented) with the variety Peace (Plant Patent No. 591).

As the result of this breeding, I have produced a new rose variety which is particularly characterized as to novelty and distinctiveness by its hardiness, its leathery and glossy foliage, the fullness and distinctive color of its blooms and their habit of holding their color very well, and its very good resistance to blackspot and mildew.

The foregoing characteristics and distinctions definitely diflerentiate my new variety from its parents, as well as from all other varieties of its class of which I am aware, and asexual reproduction of the new variety by budding, as performed by me in Holland, shows that the foregoing characteristics and distinctions come true to form and are established and transmitted through succeeding propagatrons.

The accompanying drawing shows typical specimens of the vegetative growth and flowers of my new variety in different stages of development and as depicted in color as nearly true as it is reasonably possible to make the same in a color illustration of this character.

The following is a detailed description of my new variety, with color terminology in accordance with the Horticultural Color Chart issued by the British Color Council in collaboration with the Royal Horticultural Society, except where general color terms of ordinary dictionary significance are obvious:
