Jan. 24, 1967 ARMSTRONG Plant Pat. 2,704

ROSE PLANT Filed Nov. 2, 1965 United States Patent O 2,704 ROSE PLANT David L. Armstrong, Ontario, Califl, assignor to Armstrong Nurseries, Inc., Ontario, Calif., a corporation of California Filed Nov. 2, 1965, Ser. No. 506,293 1 Claim. (Cl. Plt.22)

The present invention relates to a new and distinct variety of rose plant of the floribunda class, which was originated by me by crossing an unnamed and unpatented rose variety of unidentified parentage with the variety known as Circus (Plant Patent No. 1,382), the unnamed variety being the seed parent and the variety Circus being the pollen parent.

The general objective of this breeding was to produce a new and improved rose variety which bears multi-colored flowers, particularly combining brilliant red colors, wit-h the flowers being of a large size comparable to those of the seed parent, combined with the nearly perfect bud and flower form that are characteristic of the pollen parent, and still further combined with the good foliage and plant habit of both parents. 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 very attractive, vigorous, bushy and rounded plant habit;

(2) Attractive, dense, glossy, dark green foliage which clothes the plant well;

(3) Nearly urn-shaped flower buds;

(4) Double flowers of attractive form, said flowers being of exceptionally large size for a floribunda variety, and being borne in small to medium sized clusters which cover the plant very well; and

(5) A distinctive and attractive multicolored floral effect of the flowers, with red and yellow colors in the bud, red in the newly open flower, but changing to attractive pinks as the flowers age.

In comparison with its unnamed seed parent, which was a hybrid tea rose having very attractive and glossy foliage of large size and which bears large double flowers'of good form with a particularly brilliant and non-bluing, medium red flower color, the new variety bears its flowers usually in clusters of from small to medium size, instead of usually singly like this parent, and the flowers of the new variety are multicolored, combining reds, yellows and pinks instead of having red flowers like those of this parent.

As compared with its pollen parent Circus, the new variety bears larger flowers and the flowers have considerably more and darker red color than the flowers of this parent.

Asexual reproduction of my 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 propagati-ons.

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.
