ROSE PLANT Filed June 28, 1960 IN VE N TOR A T TOR/VEYS' United States atent Theprcsent in-vetnion relates to'a new and distinct variety of rose plant of the floribunda class, which wasdiscovered by me as a sport of. the variety Rosemary,

(Plant 'Patent No. 1,398).

"This new sport was discovered by me in one of the.

greenhouses of my assignee, located at Lynchburg, Virginia, while engaged in cutting flowers from bench plants.

of the variety Rosemary? which. were being grown under my direction and control. At the time I discovered the sport, my attention was attracted thereto by the distinctive form and clear color of the buds on one plant amongst the bench plants of Rosemary. Upon closer examination of this plant, I found that it had sported and I thereupon took steps to carefully preserve the sport, keep it under observation, and to later asexually reproduce the same. These observations and asexual reproductions, the latter being made by me by top budding on greenhouse bench plants at Lynchburg, Virginia, as well as by top budding on manetti (a species botanically identified as R. manetti and widely used in the nursery industry as understock for commercially propagating rose plants), as performed on my behalf at Livermore, California, conclusively established important differences between the new sport and the parent variety Rosemary, and that these different characteristics were fixed and established,

and capable of being transmitted through succeeding propagations.

My new sport is generally similar to the parent variety Rosemary, but is definitely distinguished therefrom, as well as from all other varieties of which I am aware, by the following characteristics which represent a new combination, particularly in the floribunda rose class:

(1) Somewhat narrower foliage and a distinctive color of the young foliage;

(2) A longer and more tapered form of the buds;

(3) Fewer flower petals;

(4) An unusual cleanliness and clarity of the flower color and the complete absence of green guard petals; and

(5) A distinctive Rose Pink, lightly overcast with Deep Rose Pink general color tonality of the open flowers.

The accompanying drawing shows typical specimens of the vegetative growth and flowers of the 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 rose variety, with color terminology in accordance with Ridgways Color Standards and Nomenclature, as based upon specimens grown in a greenhouse at Lynchburg, Virginia:
