ROSE PLANT Filed 001?. 22, 1965 United States Patent Ofiflce Plant Pat. 2,688

Patented Dec. 6, 1966 2,688 ROSE PLANT David L. Armstrong and Herbert C. Swim, both of Ontario, Calif., assignors to Armstrong Nurseries, Inc., Ontario, Calif., a corporation of California Filed Oct. 22, 1965, Ser. No. 502,786 1 Claim. (Cl. Plt.14)

The present invention relates to a new and distinct variety of rose plant of the hydbrid tea class, which was orignated by us by crossing the variety Buccaneer (Plant Patent No. 1,119) with the variety Cherry Glow (Plant Patent No. 1,490), the variety Buccaneer being the seed parent and the variety, Cherry Glow" being the pollen parent.

The general objective of this breeding was to produce new and improved varieties of roses which bear flowers in a variety of colors. The present variety is one of the resulting achievements, as evidenced by 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) A very vigorous and upright plant habit which is particularly good for a white-flowered rose variety;

(2) Large, attractive, leathery and semiglossy dark green foliage;

(3) An excellent urn-shaped bud form which holds up very well under most weather conditions;

(4) Double flowers of from medium to large size which are borne on strong stems ranging from medium length to long; and

(5) A distinctive and attarctive white flower color which has a trace of pale yellow.

In comparison with its seed parent Buccaneer, the flower color of the new variety is near white, whereas that of this parent is yellow.

As compared with its pollen parent Cherry Glow, the flowers of the now variety have considerably more petals, and the flower color is near white instead of red like the flowers of this parent.

A sexual 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 drawing 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.

The following is a detailed description of the new variety, with color terminology in accordance with Robret F. Wilsons Horticultural Colour Chart (hereinafter abbreviated as (W)) and Robert Ridgways Color Standards and Nomenclature (hereinafter abbreviated as (R) as indicated:
