Filed Feb. 4, 1960, Ser. No. 6,832.

1 Claim. (Cl. 47-61) The present invention relates to a new and distinct variety of rose plant of the grandifiora class, which was originated by us by crossing the variety Circus (Plant Patent No. 1,382) with the variety Golden Scepter (Plant Patent No. 910).

As the result of this breeding, we have achieved a new rose variety which is endowed with the following unique 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:

(1) High productivity of good quality flowers which are suitable for out flowers when grown under greenhouse conditions;

(2) A habit of bearing singly a high proportion of the flowers;

(3) A large flower size generally comparable to that of varieties of the hybrid tea class and substantially larger than that of most floribundas;

(4) Uniform flower petalage; and

(5) A general color tonality of the flowers which is a distinctive multi-color gold and yellow blend.

In comparison with its seed parent, Circus, the new variety is taller growing in its habit of growth, has longer stems on the individual flowers, produces more of its flowers singly than is usually the case of this parent, and the flowers are approximately half again larger than those of the variety Circus.

As compared with its pollen parent, Golden Scepter, the new variety has more thorns, greater flower petalage, approximately 6 more petals per flower, the flowers are a multi-color in contrast with the pure yellow flowers of this parent and there is substantially more anthocyanin pigment in the foliage and which is visible even on casual observation, as compared with the foliage of the pollen parent.

Asexual reproduction of our new variety by budding, as performed at Chino, California, shows that the aforementioned characteristics and distinctions cometrue 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 Nickerson Color Fan, published by Munsell Color Company Incorporated, of Baltimore, Maryland, except where general color terms of ordinary dictionary significance are obvious:

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

C0l0r.Outer petal: outside surface-between Strong Yellowish Pink, Plate 10R 7/9 and Strong Orange, Plate 2.5YR 7/ 10, except at base which is Vivid Yellow, Plate 2.5Y 8/ 12 and where the latter blends with the former in an area from A; to /2 inch from point of attachment; 'on the portion exposed to light as the calyx breaks in the developing bud, there is an overlay of Deep Pink, Plate 2.5R 6/11 to Strong Red, Plate 2.5R 5/ 12, with the latter usually only at the extreme tip or apex; inside surfacenear Moderate Orange Yellow, Plate 7.5YR 8/ 8 over most of petal, but with overlay of Strong Red, Plate 2.5R 8/ 12 sometimes on small area at apex and changing to Vivid Yellow, Plate 2.5Y 8/ 12 at base and blending With this latter color beginning about /8 inch from base. Intermediate petal: outside surface near Moderate Orange Yellow, Plate 7.5YR 8/ 8, except at base where color is Vivid Yellow, Plate 2.5Y 8/12 and approaching the base where these two colors blend between A and /2 inch from base; inside surface-between Moderate Orange Yellow, Plate 10YR 8/ 10 and Pale Orange Yellow, Plate 7.5YR 9/4, except at base which is Vivid Yellow, Plate 2.5Y 8/12 and area about /2 inch from base where these colors blend.
