United States Patent 2,493 ROSE PLANT Walter E. Lammerts, Livermore, Calih, assignor to Germains, Inc., Los Angeles, Calili, a corporation of California Filed Feb. 17, 1964, Ser. No. 345,545 1 Claim. (Cl. Pita-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 Charlotte Armstrong (Plant Patent No. 455) with the variety Merry Widow (Plant Patent No. 1,711);

' As the result of this breeding, I have produced a new and improved rose variety which is endowed with a unique combination of outstanding characteristics which distinguish the new variety from its parents, as well as from all other varieties of which I am aware, as evidenced by the following principal features:

(1) Vigorous, tall, upright and compact habits of growth;

(2) A habit of bearing its flowers usually singly and on long and strong cutting stems;

(3) Long pointed buds with clasping sepals, said buds being basically Scarlet in color, with a Dark Canary Yellow base;

(4) A distinctive and attractive open flower form in which the lower portions of the inner petals extend vertically upward, while the upper portions are more horizontal and arch outward from the center but cover the central stamen and pistil area until the flower ages, thereby giving the appearance of greater petalage;

(5)" A distinctive and attractive Scarlet general color tonality of the flowers which is retained without blueing as the flowers age; and

(6) An intense flower fragrance reminiscent of R. centifolio varieties even during dry weather and under other adverse conditions.

i The new variety has a taller, more upright and compact habit of growth than the parent variety Charlotte Armstrong, and in this respect, resembles the parent variety Merry Widow. Charlotte Armstrong is a hybrid of Soeur Therese (unpatented) Crimson Glory (Plant Patent No. 105), and is more upright in its growth habit than Crimson Glory, but resembles it in being base-branching, with many canes growing at approximately 45 to 50 angles with relation to the ground. Accordingly, it has a tendency toward a spreading habit of growth. By contrast therewith, even the new basal c anes of my new variety quickly curve upward as they begin to grow, with the canes extending at angles of approximately 75 to 90 in relation to the ground. As

the result, the plant of my new variety is much more compact in its growth habit, thus taking up less space in the garden than such base-branching varieties as Crimson Glory, Sierra Glow (Plant Patent No. 521), and even Charlotte Armstrong.

, Although the new variety is a hybrid tea with most of the flowers being borne singly on long and strong cutting stems, the habit and vigor compare favorably with the parent variety Merry Widow, and it is more vigorous than Charlotte Armstrong in respect to both height and total growth. The foliage, thorns and other plant characteristics are otherwise quite similar to those of Charlotte Armstrong.

While the buds of my new variety are similar to those of Charlotte Armstrong, particularly in respect to their long pointed form, with clasping sepals, the basic color of the buds of the new variety is more Scarlet because in size, form and color, but the color is more Scarlet in general color tone. The inner petals'have the same arching tendency as the flowers of Charlotte Armstrong,

which gives the impression of greater petalage, although the flowers actually have only from 2.5 to 35' petals.

The newly open flower of the new variety is also more Scarlet than that of Charlotte Armstrong, and therefore does not tend to blue or show as much magenta coloration with age.

The most distinctive characteristic of the new variety is its intense flower fragrance which is reminiscent of the older R. centifolza varieties. It is much more fragrant than Merry Widow or even Chryster Imperial (Plant Patent No. 1,167). Accordingly, it corrects what undoubtedly is a fault in Charlotte Armstrong, which, at its best, has only a slight, rather delicate fragrance which is dependent for its expression on conditions of optimum humidity and temperature. Even under the driest and most adverse conditions, my new variety is intensely fragrant, and a pleasing old-fashioned rose perfume is easily noted in the average living room even when only one newly opened flower of the new variety is displayed in the room.

Asexual reproduction of my new variety by budding, as performed by me at Livermore, California, shows that the foregoing characteristics and distinctions come true to form and are established and transmitted through sucseeding 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 British Colour Council, except where general color terms of ordinary dictionary significance are obvious, as based upon observations of specimens grown at Livermore, California:
