3,649 ROSE PLANT Dorothy Jean Searles Bailey, 1101 Lomita Drive, Bakersfield, Calif. 93307 Filed May 10, 1973, Ser. No. 359,096 Int. Cl. A01h /00 US. Cl. Plt.14 1 Claim The present invention relates to a new and distinct variety of rose plant of the Hybrid Tea class. It was originated by me by crossing the rose variety known as Virgo with the variety known as Ivory Fashion (Plant Patent No. 1,688).

As the result of this breeding, I have produced a new and improved variety which is distinguished from its parents, as well as from all other rose varieties of which I am aware, as evidenced by the unique combination of characteristics which are outstanding therein:

(1) A neat, moderately vigorous upright bush of typical Hybrid Tea habit;

(2) Medium large, Dark Green foliage that abundantly covers the plant;

(3) Abundant bloom production from early spring until fall, especially during the warmest periods;

(4) Flowers borne singly to each stem, the stems being strong, medium long;

(5) Thick velvety petals that do not spot pink or brown or bruise easily;

(6) Urn shaped bud, l fii-l /z inches long, that slowly opens into a high-centered bloom of very regular petal conformation;

(7) Clean white color of petals that shades into Naples Yellow 403/3 at the base; and

(8) A slight clean Sweetbriar fragrance.

In comparison with the parent varieties, this new variety has inherited the habit of its maternal parent, Virgo, both having moderate vigor, upright bush, typical Hybrid Tea habit, and medium sized dark green foliage. The paternal parent, Ivory Fashion, has contributed increased mildew resistance to the new variety and harder foliage, compared to Virgo, Virgo is a clear white under ideal conditions, but more often is spotted with pink and bruises moderately easily. Ivory Fashion is a smooth ivory in the range of Naples Yellow 403/3, but with thicker petals, more resistant to spotting and bruising. The new variety is a clear white shading into Naples Yellow 403%3 toward the base. The thick, clean petals with the absence of spotting and resistance to bruising has been inherited by the new variety from Ivory Fashion, and is an important characteristic for white roses. The bloom of Ivory Fashion is small but high-centered and of very regular conformation, having a fine small urnshaped bud. Virgo has a larger bud and a nice high centered bloom. The new variety has inherited the bud and bloom size from Virgo, and the improved bud and bloom form from Ivory Fashion.

The accompanying photographs show typical specimens of the vegetative growth and flowers of my new variety in different stages of development and are depicted in color as nearly true as it is reasonably possible with color photography.

The following is a detailed description of my new variety, with color terminology in accordance with the Horticultural Colour Chart of the British Colour Council, except where general color terms of ordinary dictionary significance are obvious, as based upon observations of specimens grown at Shafter, California:
