ETAL Plant Pat. 2,82

D. L. ARMSTR ROSE PLANT Filed Feb. 8, 1967 United States Patent 2,829 ROSE PLANT David L. Armstrong and Herbert C. Swim, Ontario, Califi, assignors to Armstrong Nurseries, Inc, Ontario, Calif., a corporation of California Filed Feb. 8, 1967, Ser. No. 614,756 1 Claim. (Cl. Pit-18) The present invention relates to a new and distinct variety of rose plant of the grandiflora class, which was originated by us by crossing the variety known as Charlotte Armstrong (Plant Patent No. 455) with the variety known as Cherry Glow (Plant Patent No. 1,490), the former being the seed parent and the latter being the pollen parent.

The primary objective of this breeding was to produce a new and improved rose variety having the vigor and floriferousness of the parent variety Cherry Glow, combined with the excellent urn-shaped bud form of both parents, the large flower size and flower form of the parent variety Charlotte Armstrong, and with the flower color being in the red to pink color range. This objective was fully achieved, along with other desirable features, 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 we are aware:

(1) A vigorous and attractive plant habit, intermediate upright and spreading;

(2) Medium to large, dark green, leathery, semi-glossy and disease resistant foliage;

(3) A very floriferous habit, with the flowers borne on medium length stems and borne both singly and in small clusters typical of the grandiflora class;

(4) Attractive urn-shaped flower buds, and a relatively high-centered open flower form, and showing petals reflexed in a manner similar to those of Charlotte Armstrong;

(5) A flower size from medium to large, with from to petals; and p (6) A distinctive and attractive flower color ranging between Neyron Rose and Dawn Pink, with darker pink on the reverse side of the petals.

In comparison with its seed parent Charlotte Armstrong, the new variety primarily differs therefrom by being a bicolor, with light pink on one side and darker pink on the reverse side of the flower petals, as distinguished from the dark cerise pink or light red color of the flowers of Charlotte Armstrong, and the plant of the new variety is more vigorous, with the leaves being more glossy than those of this parent.

As compared with its pollen parent Cherry Glow, the new variety primarily differs therefrom by being a light and darker pink bicolor as aforementioned, whereas the flowers of Cherry Glow are red,

While the new variety resembles a fairly similar variety known as Columbus Queen (Plant Patent No. 2,170), it differs therefrom by having a more spreading plant habit, a somewhat greater tendency to bear flowers in small clusters, a slightly more bluish pink flower color, and an open flower form that is more high-centered, with the petals more definitely reflexed outward as typical of Charlotte Armstrong.

Asexual reproduction of our new variety by budding, as performed at Ontario, Calif., shows that the foregoing 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, with some of the flowers Plant Pat. 2,829 Patented Aug. 20, 1968 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.
