ROSE PLANT Filed Jan. 17, 1969 United States Patent 2,992 ROSE PLANT Dorothy S. Whisler, Shafter, Calif., assignor, by mesne assignments, to Gro-Plant Industries, Inc., Monticello,

Fla., a corporation of Florida Filed Jan. 17, 1969, Ser. No. 792,178 Int. Cl. Alllh /00 US. Cl. Plt.-15 1 Claim The present invention relates to a new and distinct variety of rose plant of the Hybrid Tea class, which was originated by me by crossing the rose variety known as Charlotte Armstrong (Plant Pat. No. 455expired) with the rose variety known as Fred Howard (Plant Pat. No. 1,006), the former being the seed parent and the latter being the pollen parent.

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

(1) A neat, vigorous, upright, moderately tall and well-clothed plant habit;

(2) Larger than average foliage which is semi-glossy and medium dark green in color;

3) Moderate thorniness, with the thorns being slender, almost straight and inclining only slightly downward;

(4) Remarkable bloom abundance and rapid bloom recycle, said blooms being borne singly or in clusters of 2 or 3 to the stem, on strong stems of moderate length;

(5 Ovoid bulbs which open to excellent high-centered blooms which maintain in all stages an elegant regular spiral petal arrangement and even ,imbrication;

(6) Good flower petalage of from 55 to 65 petals and an almost complete lack of petaloids;

(7) A distinctive and attractive medium yellow bud and opening flower color, finishing to an even creamy yellow color, with both sides of the petals being the same color shade, but with the base of each petal being a deeper yellow color, and the center of the opening blooms having a more intense color eiiect and giving a very attractive glowing appearance to the flowers;

(8) A very slight tea flower fragrance; and

(9) A substantially sterile habit of the flowers, with fewer than average stamens which are grouped regularly around the stigmas.

The principal and significant differences between my new variety and its parents will be apparent from the following comparison:

My new variety most nearly resembles the rose variety known as Kings Ransom (Plant Pat. No. 2,103), but is distinctly different therefrom as will be apparent from the following comparison:

Asexual reproduction of my new variety of budding, as performed at Shatter, 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 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.

The following is a detailed description of the new variety, with color terminology in accordance with the Horti-cultural Colour Chart of the British Colour Council, except where general color terms of ordinary dictionary significance are obvious.
