ROSE PLANT Filed Aug. 6, 1964 United States Patent O 1 Claim. (Cl. Pit-6) The present invention relates to a new and distinct variety of rose plant of the climber class, which was originated by me by crossing the variety known in the United States as Spectacular (U.S. Plant Patent No. 1,416) with an unnamed and unpatented seedling of Rome Glory (U.S. Plant Patent No. 304) La Vaudoise (unpatented), the variety Spectacular being the seed parent, and the unnamed seedling being the pollen parent.

The primary objective of this breeding was to combine the ever-blooming climbing habit, floriferousness and orange-red color of the seed parent Spectacular with the non-fading flower characteristic and high quality foliage of the pollen parent. This objective was fully achieved, along with other desirable improvements, as evidenced by the following unique combination of characteristics which are outstanding in the new variety and which distinguish it from its parents, as well as from all other varieties of which I am aware:

(I) A vigorous, climbing plant habit, with ample disease-resistant, glossy foliage, which is reddish when young but which changes to a rich dark green color when mature;

(2) A relatively ever-blooming flowering habit, with heavy flowering in the spring and intermittent blooming thereafter throughout the remainder of the growing season;

(3) Excellent floriferousness, with double flowers of medium size borne both singly and in small clusters;

(4) A flower form which is above average, with highcentered, urn-shaped buds; and

(5) A relatively non-fading bright, rich Scarlet to orange-red color of the flowers, which is the most outstanding characteristic of my new rose variety and which is unusual for a rose of the climbing class.

In comparison with its seed parent Spectacular, the new variety has a bright, rich, relatively non-fading Scarlet or orange-red color which is always good when compared to the orange-red or Scarlet color of the flowers of Spectacular, which tends to fade more and in some weather conditions tends to take on a dull cast in the case of the flowers 0f Spectacular.

As compared with the unnamed pollen parent which bears flowers of a relatively non-fading bright Vermilion Red color, my new variety is difierentiated therefrom by being a climber instead of a bush like this parent.

Asexual reproduction of my new variety by budding, as performed in France and also at Ontario, California, U.S.A., shows that the aforementioned characteristics and distinctions come true to form and are established and transmitted through succeeding propogations.

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 Robert F. Wilsons Horticultural Colour Chart (hereinafter abbreviated as W) and Robert Ridgways Color Standards and Nomenclature (hereinafter abbreviated as Plant Pat. 2,573 Patented Nov. 16, 1965 lCe R), except where general color terms of ordinary dictionary sigmficance are obvious:
