ROSE PLANT Filed July 2, 1973 United States Patent 3,621 ROSE PLANT Marie-Louise Meilland, Antibes, France, assignor to Michigan Bulb Company, Grand Rapids, Mich. Filed July 2, 1973,.Ser. No. 375,442 Int. Cl. A01h 5/00 US. Cl. Plt.20 1 Claim ABSTRACT OF THE DISCLOSURE SUMMARY OF THE INVENTION 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 seedling by crossing Royal Velvet (U.S. Plant Pat. No. 1,911) with Chrysler Imperial (U.S. Plant Pat. No. 1,167), which unnamed seedling was crossed with Pharaoh (U.S. Plant Pat. No. 2,859).

As a result of this breeding, I have produced a new, improved and useful rose variety which is distinguished from its parents and all other roses of which I am aware, as evidenced by the following unique combination of characteristics which are outstanding therein:

1. Intense, vivid orange-red color.

2. Well formed, attractive bud of distinctive color.

3. Attractive, large flower of good form and vivid color which becomes more intense in cool weather.

4. Upright plant of well branched growth habit carrying flowers usually one to the stem at the top of the plant.

5. Dark, glossy green foilage of large size covering the plant well.

6. An abundance of prickles large, medium and small on all stems and branches.

The seed parent of my new discovery was an unnamed seedling of a cross of Royal Velvet (U.S. Plant Pat. No. 1,911) with Chrysler Imperial (U.S. Plant Pat. No. 1,167), characterized by bright red color and compact, well branched plant. My new discovery differs from its seed parent by having an open flower of more flat form with petals only lightly roller outward, with more orange tones in the flower color and a plant which grows taller and with more glossy foliage.

As compared with its pollen parent, Pharaoh (U.S. Plant Pat. No. 2,859), my new rose has more orange color in the flower with less black-red marking on the outer petal and a plant of more upright and taller growth producing more flowers on shorter stems.

Asexual reproduction of my new rose by budding as performed in France and at West Grove, Pa., shows that the distinguishing characteristics come true to form and are established and transmitted through succeeding propagations.

BRIEF DESCRIPTION OF DRAWING The accompanying drawing shows typical specimens of the vegetative growth and flowers of my new rose 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.

DETAILED DESCRIPTION OF DISCLOSURE The following is a detailed description of the new variety, with color terminology in accordance with the Colour Chart of the Royal Horticultural Society, except where Plant Pat. 3,621 PatentedSept. 24, 1974 ice I general color terms of ordinary dictionary significance are obvious:

This description of a newly opened flower was made from a rose grown in early September 1971, at West Grove, Pa.

Intermediate petal: Outside surface: 50A; inside surface: 43A. Inner petal: Outside surface: 50A; inside surface: 43A.

This description was made from a rose that was open for three days outdoors in early September 1971, at West Grove, Pa.

I claim:

1. A new and distinct variety of rose plant of the Hybrid Tea class, substantially as herein shown and described, characterized particularly as to novelty by the unique combination of a tall, vigorous, upright, freely branched habit of growth; with all canes and branches attractively covered with large, glossy, dark green foliage, and with the presence of a large number of prickles, flowers of vivid and intense orange-red color, large size with bud of attractive form and open flower of flat form with petals lightly rolled outward often showing the stamens and having a light tea fragrance, the plant having winter hardiness and resistance to disease typical of the Hybrid Tea class.
