ROSE PLANT Filed Oct. 29, 1956 United States Patent ROSE PLANT Milton L. Whisler, Granada Hills, Califl, assignor to Ger- ;fnains, Inc., Van Nuys, Calif., a corporation of Caliorma Application October 29, 1956, Serial No. 619,095-

1 Claim. (Cl. 47-61) The present invention relates to a new and distinct variety of rose plant of the climber class, which was dis-' covered by me as a bud sport of the variety Queen Elizabeth (Plant Patent No. 1,259), but which is distinguished from the latter parent variety by its climbing habit of growth. The new variety was discovered by me amongst a cultivated block of Queen Elizabeth plants which were being grown under my direction and supervision at Saugus, California, on property controlled by my assignee.

At the time of my discovery, my attention was attracted to the new variety by the unusually vigorous and climbing habit of a particular plant of the Queen Elizabeth variety in the block of plants mentioned above. Upon closer examination thereof, I found that the parent plant had sported, and I thereupon promptly took steps to preserve, asexually reproduce and observe this sport for the purpose of determining whether or not its climbing habit was fixed and transmissible by asexual reproduction. The climbing habit was fully confirmed by such observations and by asexual reproduction by budding, as performed by me at Saugus, California, and I have therefore established that the climbing habit of growth of the new variety comes true to form and is transmissible through succeeding propagations.

The parent variety (Queen Elizabeth) is a bush rose of the hybrid tea class, and is primarily notable for its unusual vigor and upright habit of growth, its large, leathery, glossy, dark green leaves and the abundance thereof, its abundant production of flowers which are borne on relatively long cutting stems, and by the unusually clear Carmine Rose to Dark Pink general color tonality of its flowers which shade to lighter shades of Carmine Rose to Dark Pink, with the outer portions of the petals becoming heavily peppered with Carmine where the sunlight strikes strongest. This bush variety, so far as I am aware, has never exhibited a climbing habit, and its growth has usually been of the average strong bush rose. The new variety herein is substantially identical to its parent in all respects, except that it is definitely a climber, and like its parent, the plant is heavily clothed with large, leathery, dark green foliage, and is very floriferous.

In view of the general similarities between my new variety and its parent, except as noted above, it is unecessary to describe or illustrate the new variety in detail,

since it otherwise substantially conforms to the detailed Color Chart of the British Color Council, except where general color terms of ordinary dictionary significance are obvious:

Type: Hardy; climber; for out flowers and for garden decoration.

Class: Hybrid tea.

Parentage: Sport of Queen Elizabeth.

Bloom:

Size (when fully 0pen).From 3 /2 inches to 4 inches. Petalage.-Fr0m 37 to 40 petals; arranged regularly.

Pezals.Texture-medium thin; with both inside and outside satiny. Shape: outsideobovate, with apex ,5 inch long; no notches; intermediate-obovate; usually with one notch, but occasionally some with short apex.

This description of a newly opened flower was made from a rose grown outdoors in the month of September at Saugus, California:

This description was made from a rose that was open for 3 days outdoors in the month of October, at Saugus, California:

Colon-Outer petal: outside surface-Neyron Rose, Plate 623/2; inside surfaceCarmine Rose,

Reproductive organs Stamens: Medium number; arranged irregularly about pistils.

I claim:

A new and distinct variety of rose plant of the climbing hybrid tea class, substantially as herein shown and described, characterized particularly as to novelty by being substantially identical with its parent variety Queen Elizabeth (Plant Patent No. 1,259), including the latters foliaceous habit and abundant, large, leathery,

dark-green foliage which heavily clothes the plant, but being essentially distinguished therefrom by its vigorous r and climbing habit of growth. 0
