'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 us by crossing the variety Charlotte Armstrong (Plant Patent No.455) with the variety Signora" (Plant Patent No. 201).

As the result of this breeding, we have created a new rose variety which is endowed with the following unique and desirable combination of characteristics which are outstanding therein and which distinguish it from its parents, as well as from all other varieties of which we are aware:

(I) Vigorous and productive plant habits;

(2) A neat and compact plant form, with many erect branches which are well-placed and well-proportioned;

(3) Attractive foliage of large size and abundance, which give the plant a well-clothed appearance;

(4) A relative scarcity of prickles on the flower stems, as compared with most varieties now in commerce;

(5) Graceful proportions of the bud in relation to the number of flower petals; and

(6) A distinctive and variable blend of pink and yellow ,flower color pigments, but generally ranging in the colors popularly referred to as salmon, orange and pink, as well as combinations of these colors, thus re sulting in an unusual color tonality that is definitely different from that found in any other rose now in comnierce.

In comparison with its seed parent, Charlotte Armstrong, our new rose variety is more upright in its habit of growth; has glossy foliage in contrast to the nonglossy foliage of this parent; has fewer prickles than its parent; produces flowers of salmon and orange color tones which are quite dilferent from the pink and red color tones of the flowers of Charlotte Armstrong; and the flowers have a much stronger fragrance than those of this parent.

As compared with its pollen parent, Signora, the new variety is more productive and has a substantially bushier plant habit; the individual flower stems are substantially shorter than those of this parent; the flower bud are substantially larger in proportion to their width than those of this parent; and the flowers of the new variety are dominated by pink and orange colors, while those of this parent are dominated by red and yellow colors and combinations thereof.

Asexual reproduction of our new rose variety by budding, as performed at Chino, California, shows that the aforementioned characteristics and distinctions come true to form and are established and transmitted through succeeding propagations.

The accompanying drawing shows typical specimens of the vegetative growth and flowers of our 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 our new variety, with color terminology in accordance with the nited States Patent 0 ICC Nickerson Color Fan, published by Munsell Color Company, Inc., of Baltimore, Maryland, except where general color terms of ordinary dictionary significance are obvious:

This description of a newly opened flower was made from a rose grown in a greenhouse at Chino, California, during the month of December:

Colon-Outer petal: outside surface-near Deep Pink, Plate 2.5R6/11 over upper /2 of petal, but blending with Brilliant Yellow, Plate 5Y9/9, progressing toward base and becoming this latter color entirely /8 inch from point of attachment; inside surfacenear Deep Pink, Plate 10RP6/ 12 3 over outer /z of petal, but with veins distinctly marked with Vivid Red, Plate 5R5 13 the former color blends with some shade of bright yellow in i the inner or lower /2 of petal to give a shade near Strong Reddish Orange, Plate 7.5R6/ 12, but becoming Brilliant Yellow, Plate 5Y9/9 oneeighth inch from point of attachment.

Inner petal: outside surface-base near Brilliant Greenish Yellow, Plate 7.5Y9/8, beginning to blend with pink about A inch from base and progressively diminishing in effect toward apex until all yellow influence is lost about /2 inch from apex and Strong Pink, Plate 1ORP7/8 appears, with much of the blended area near Moderate Yellowish Pink, Plate 7.5R8/6; inside surfaceupper /2 of petal near Deep Pink, Plate l0RP6/12, with base Brilliant Greenish Yellow, Plate 7.5Y9/8 to inch from point of attachment; remainder of petal near Moderate Yellowish Pink, Plate l0R8/6; in the area influenced or entirely occupied by pink tones, veining of near Deep Pink, Plate 10RP6/12 is noticeable.
