July 5, 1966 D. 1.. ARMSTRONG ETAL Plant 2,653

ROSE PLANT Filed Aug. 17, 1965 United States Patent 2,653 ROSE PLANT David L. Armstrong and Herbert C. Swim, Ontario, Cal fl, assignors to Armstrong Nurseries, Inc., Ontario, Cahf., a corporation of California Filed Aug. 17, 1965, Ser. No. 480,536 1 Claim. (Cl. Plt.18)

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 known as Fandango (Plant Patent No. 894) with an unnamed variety which is the subject of Plant Patent No. 1,277, the variety Fandango being the seed parent and the unnamed variety being the pollen parent.

The general objective of this breeding was to produce a new and improved rose variety which bears flowers whose color falls in the pink or light red color range and of the hybrid tea or grandiflora type, combined with the large flower size, good bud form and large, glossy, disease resistant foliage characteristic of the seed parent, along with the floriferousness, excellent, dense, bushy habit, and vigor that are characteristic of the unnamed pollen parent.

This objective was fully achieved, along with other desirable improvements, as evidenced by the following characteristics which are outstanding in the new variety and which distinguish it from its parents, as well as from all other varieties of which we are aware:

(1) An upright-spreading habit, with a vigor consid: erably greater than that of the average hybrid tea rose variety;

(2) Attractive, dark green, medium to large, semiglossy, disease resistant foliage;

(3) A very floriferous habit with the flowers often borne singly, but also often borne in small clusters on the most vigorous shoots and bottom breaks;

(4) An excellent urn-shaped bud form and attractive .and graceful open flower form, with the flower being moderately double and of medium size; and

(5) A distinctive and attractive general color tonality of the flowers ranging between Phlox Pink and Fuchsine Pink, but becoming lighter with age.

In comparison with its seed parent Fandango, the new variety is considerably more vigorous, tends to bear flowers in clusters on the more vigorous shoots rather than usually singly as in the case of Fandango, the flowers of new variety have considerably more petals, and the flower color is pink, as distinguished from the cherry red flowers of Fandango.

As compared with its unnamed pollent parent, the flowers of the new variety are considerably larger in size, and the flowers are often borne singly, as well as in small clusters, whereas those of the pollen parent usually are borne in clusters only and the clusters are larger.

Asexual reproduction of our new variety by budding, as

performed at Ontario, California, shows that the foregoing characteristics and distinctions come true to form and are established and transmitted through succeeding propagations.

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