ROSE PLANT Filed Feb. 25, 1963 United States Patent 2,370 ROSE PLANT Herbert C. Swim, Ontario, and 0. L. Weeks, Chino, Caiif., assignors, by mesne assignments, to the Cunard-Pyle Company, West Grove, Pa, a corporation of Pennsyl- Vania Filed Feb. 25, 1963, Ser. No. 260,932 1 Claim. (Cl. Plt.2t))

The present invention relates to a new and distinct varliety of rose plant of the hybrid tea class, which was originated by us by crossing the variety Chrysler Imperial (Plant Patent No. 1,167 with the variety Charles Mallerin (Plant Patent No. 933).

As the result of this breeding, we have produced a new and improved rose variety having 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) Extraordinary vigorous growth which is evidenced by the fact that the new variety is among the largest in the hybrid tea class, if not actually the largest;

(2) A habit of usually producing only one flower to a stem, with the flowers being borne on exceptionally long stems growing from the base or near the base of the plant, and the stems being substantially less prickly than those of most red hybrid tea rose varieties;

(3) Exceptionally large flower size, with the flowers being the largest of any red roses of the hybrid tea class previously known to us;

(4) Good flower petalage normally numbering from 30 to 40 petals, with the petals being very large and broad;

(5) A regular arrangement of the petals in the open flowers, with a high degree of imbrication;

(6) A distinctive and attractive general color tonality of the flowers which may be generally described as dark red, but the color being lighter and brighter than the flowers of such varieties as the parent variety Charles Mallerin, said flowers also having a white or yellow vegetative streak on the midrib of some of the outer petals of the flowers; and

(7) A distinctive and pleasing flower fragrance composed of a blend of tea and damask.

In comparison with its seed parent, Chrysler Imperial, the new variety has a much taller and more vigorous plant habit, with heavier and longer main stems, branches and flowering stems, with fewer prickles, both large and small; and bears substantially larger flowers on the average, said flowers having substantially larger individual petals, and the petals having a substantially larger breadth in proportion to their length than the flower petals of this parent variety.

As compared with the pollen parent, Charles Mallerin, the new variety has a taller, more vigorous and more symmetrical plant habit, with many more branches, and the main stems, branches and flowering stems being of substantially larger caliper and greater length; fewer prickles, both large and small; a substantially larger average flower size; only stipitate glands on the peduncle, as distinguished from the numerous small prickles on the peduncle of this parent variety; and a definitely lighter and brighter shade of red flower color than the flowers of Charles Mallerin.

Asexual reproduction of our new variety by budding, as performed at Chino, California, shows that the aforementioned 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 diflerent stages of development and as depicted in color Plant Pat. 2,379 Patented Mar. 3, 1964 ice as nearly true as it is reasonably possible to make the same in a color illustration of this character.

This description of a newly opened flower was made from a rose grown outdoors during the month of December at Ontario, California:

Colon-Outer petal: outside surface-between Dark Red, Plate 25R 3/7 and Dark Purplish Red, Plate 10RP 3/10, sometimes overlaid irregularly with black or'dark purple; inside surface-small area about point of attachment near Strong Orange Yellow, Plate IOYR 7/ 10, with remainder of petal varying in red coloration depending largely on the amount of overlay of black and Dark Purplish Red, Plate 10R? 3/10, with the basic color being between Dark Red, Plate 2.5A 3/ 7 and Moderate Red, Plate 2.5R 4/10; the overlay tending to follow the veinings although sometimes becoming general over the upper half of the petal, with 1 or 2, sometimes more, of the outside petals of flowers produced on the longer basal stems often containing a vegetative streak of white or pale yellow along the midrib, beginning near the base and extending toward the apex, said streak ranging from /s inch to inch wide and usually more typical in flowers produced on long basal shoots, but otherwise mostly lacking or being inconspicuous. Intermediate petal: outside surface-between Moderate Red, Plate 2.5R 4/ 10 and Deep Purplish Red, Plate IORP 3/ 10, with color being somewhat closer to the latter on the upper half and closer to the former at the base, with point of attachment Vivid Yellow, Plate 5Y 8/ 12; inside surfacesmall area at base of petal being near Strong Orange Yellow, Plate lYR 7/10, with remainder of petal being between Dark Red, Plate R 3/7 and Strong Red, Plate 5R 4/12, the latter color dominating at the base and the former dominating over the remainder of the petal, but these colors appearing more vivid due to an underlying yellow color. Inner petal: outside surfacesmall area about point of attachment being Vivid Yellow, Plate SY 8/ 12 and extending upward as an underlay which atfects the value of the red color to varying degrees over the lower half of the petal, with the lower portion of the petal being near Strong Red, Plate 5R 4/12, gradually giving way and progressing upward to between Deep Purplish Red, Plate 10RP 3/10 and Strong Purplish Red, Plate IORP 4/12; inside surface small area about base of petal being near Moderate Orange Yellow, Plate 10Y 8/ 10; progressing upward and beginning with Moderate Red, Plate 2.5R 4/10, the color gradually changes and deepens toward apex so that most of the upper portion of the petal is between Dark Red, Plate 2.5R 3/ 7 and Dark Purplish Red, Plate 10RP 3/10, al though more vivid due to an apparent underlay of some shade of yellow.

This description was made from a rose that was open for three days outdoors during the month of December at Ontario, California:

Inner petal: outside surfacepoint of attachment being Vivid Yellow, Plate 5Y 8/12, with lower portion of petal being influenced by an underlay of this color, but being between Strong Red, Plate 5R 4/12 and Moderate Red, Plate R 4/10, and upper portion of petal being near. Moderate Red,

Plate 2.5R 4/10; inside surface small area about point of attachment being near Vivid Yellow, Plate 2.5Y 8/12, with lower part of petal basically appearing near Strong Purplish Red, Plate IORP 5/12, overlaid along midrib with Vivid Red, Plate 5R 5/12, and with upper portion being basically near Strong Purplish Red, Plate 10RP 4/12, but strongly influenced by an overlay of Strong Red, Plate 5R 4/12, which has slightly more intensity in the veinings and their reticulations.

General color efiect.l\lewly opened flower-basically near Moderate Red, Plate 2.5R 4/10, but overlaid strongly with Dark Red, Plate 2.5R 3/ 7 and variably with black. 3-days open-outer portion basically Moderate Red, Plate 25R 4/10, changing in various degree to- Deep Purplish Red, Plate IORP 3/10, with center of flower being between Strong Red, Plate SR 4/ 12 and Moderate Red, Plate 2.5R 4/10.
