ROSE PLANT Filed Sept. 26, 1963 United States Patent 2,462 ROSE PLANT Pedro Dot, Barcelona, Spain, assignor to The Conrad- Pyle Company, West Grove, Pa., a corporation of Pennsylvania Filed Sept. 26, 1963, Ser. No. 311,930

1 Claim. (Cl. Plt.20)

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 variety Baccara (U.S. Plant Patent No. 1,367) with the variety Peace (U.S. Plant Patent No. 591, known in Europe as Mme. A. Meilland) As the result of this breeding, I have produced a new and improved rose variety as evidenced by the following unique combination of characteristics which are outstanding therein and which distinguish the same from its parents, as well as from all other varieties of which I am aware:

(1) A tall and upright habit of growth;

(2) A habit of bearing flowers both singly and several to a stern;

(3) The production of blooms of moderate having from 50 to 55 petals;

' (4) A distinctive and unusual variation in the color of the flower petals due to exposure to sunlight, as evidenced by a change of the dominant Rose Pink color of the open blooms to a Bright Scarlet color;

(5) Very good cut flower longevity, as compared with that of the average garden rose variety; and

(6) A slight musk-like fragrance.

In comparison with its seed parent Baccara, the new variety has better balance in its habit of growth; the flower buds are more pointed; and the flower petalage is considerably less than that of this parent.

As compared with its pollen parent Peace, the folisize and age of the new variety is smaller and less leathery; the

flowers are also smaller; and the flower color is completely different and bears no resemblance to the flower color of this parent, being from Rose Pink to Scarlet in contrast to the yellow-blushed pink color of the flowers of Peace.

Asexual reproduction of the new variety by budding, as performed in Spain and at West Grove, Pennsylvania, U.S.A., shows that the aforementioned characteristics and distinctions come true to form and are established and transmitted through succeding 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 my new variety, with color terminology in accordance with the Horticultural Colour Chart of the Royal Horticultural Society, except where general color terms of ordinary dictionary significance are obvious:

This description of a newly opened flower was made from a rose grown outdoors during the moth of August at West Grove, Pennsylvania, U.S.A.:

Color.-Outer petal: outside surfaceRose Madder, Plate 23/1, with base area surrounding point of attachment being tinted with Rose Madder, Plate 23/3; inside surface-Rose Madder, Plate 23/2, becoming Signal Red, Plate 719/3 where exposed to light. Intermediate petal: outside surface Rose Madder, Plate 23/2 over the central body of the petal, shading to Rose Madder, Plate 23/1 around upper margins and with tinting of Rose Madder, Plate 23/3 surrounding point of attachment; inside surfaceRose Madder, Plate 23/2, with slightly darker shadings on the lateral margins of the petals, and changing sharply to Signal Red, Plate 719/ 3 where exposed to sunlight. Inner petal: outside surfaceRose Madder, Plate 23/1; inside surfaceCla-ret Rose, Plate 021/ 1 covering upper half of petals, with lower half being dominated by Carmine, Plate 21/2.

This description was made from a rose that was open for three days outdoors during the month of August at West Grove, Pennsylvania, U.S.A.:

Colon-Outer petal: outside surface-Tyrian Rose, Plate 24/2, irregularly shading with Rose Madder, Plate 23/ 1; inside surface-Carmine Rose, Plate 621/2 covering main body of petals, becoming sharply overlaid with Signal Red, Plate 719/3 where exposed to sunlight.

General color eflecL-Newly opened flower-Signal Red, Plate 719/3, somewhat reduced in intensity by overlying tints of Crimson, Plate 22/2, with general color effect in cloudy weather being dominantly Rose Madder, Plate 23/2. Three days penSignal Red, Plate 719/2, overlying Crimson, Plate 22/2.

Behavior.-Drop otf cleanly; affected by hot, dry, sunny weather by intensification of the Scarlet coloration which can be absent in the opening stages in dull, cloudy weather.
