Dec. 11, 1956 T. E. MOTOSE Plant Pat. 1,537

ROSE PLANT Filed Jan. 27, 1956 United States Patent This discovery or invention relates to a new and distrnct variety of plant of the genus Rosa originating as a mutation of the variety known in commerce as Vierlanden (not patented).

The said sport or mutant was found by me on a Vierlanden bush grown personally by me in my experimental rose bed in Fairport, N. Y. I am the sole owner of both the parent bush and the sport.

Vierlanden, the parent variety, is a tall bush type rose plant of the hybrid-tea class, with abundant thorns and bearing deep salmon pink blooms which have a magenta overcast on the outer larger petals.

One of my Vierlanden bushes produced a sport possessing thorny cane and bearing clear rose pink blooms. I permitted this sport to remain and grow on the Vierlanden bush. Later I removed the branches bearing the regular Vierlanden blooms so that all the nourishments would go to the new sporting branch. As a result, the sport grew and produced many new branches, some very heavily thorned while others less thorned. I found among the medium and the heavily thorned branches, one smooth branch with one inconspicuous looking thorn or prickle. I, then, removed and discarded one by one all the thorny branches until only the almost thornless one was left to receive all the nourishments from the old root-system. The present discovery or invention, the subject of this application, is the variety of rose plant produced asexually from the said almost thornless branch of the said thorned sport of Vierlanden.

DIFFERENTIATING CHARACTERISTICS The new variety, the subject of this application, is distinguished from its parent Vierlanden on several major characteristics as shown in the following comparison:

New variety.-Rose Bengal (Plate No. 25/3 Hort.) colored blooms without any magenta overcast; medium thick and medium size petals.

Vierlanden.Very deep salmon pink colored blooms, with magenta overcast on the larger outer petals; thick and large petals.

Tests conducted in the experimental rose garden in Fairport, N. Y., show that the colors of the two roses are sufliciently different as to be distinguishable even at a distance of 150 or more feet in ordinary daylight by persons of normal eyesight.

New variety.Large, long canes; about a. dozen or less thorns on the lower parts of an average bush; as a general rule no thorns on the upper canes or upper parts of the bush; averaging one or less thorn on a branch.

Vierlanden.Large, long canes; 50 to 100 thorns on an average branch.

The difference in the quantity of thorns on the two varieties is sufliciently great that an average person, blind-folded, can separate the new variety from Vierlanden by the sense of touch alone. (Tests conducted in the experimental garden in Fairport, N. Y.)

New variety.Same texture and size of foliage as those on Vierlanden; same color of leaves as those of parent.

Vierlanden.-Leathery textured leaves; Spinach Green (Plate No. 5 Ridg.) mature leaves; Light Greenish Yellow (Plate No. 5 Ridg.) young leaves; ovoid and slightly pointed leaflets.

New variety.Similar size bush (average specimen) and growth habit as those of Vierlanden.

Vierlanden.Large, tall bush; strong, vigorous growth.

New variety.A mixture of sweet Rosa centifolia and Rosa damascena fragrances, without the scent of tea.

Vierlanden.-A mixture of sweet Rosa centz'folia and Rosa damascena fragrances, with an appreciable addition of tea scent.

Vierlanden is universally recognized as a distinct variety and is listed in authoritative publications, such as the fourth edition of Modern Roses. The combination of the various characteristics possessed in common by Vicrlanden and this new variety and the various characteristics not possessed by Vierlanden but possessed by this new variety makes this new variety different from Vierlanden and all other varieties.

Asexual reproductions of the said new variety by the usual methods of budding, grafting and cutting, performed by me in Fairport, N. Y., show that the distinguishing characteristics described in the preceding paragraphs and in the detailed specification that follows come true to form and are fully established and transmitted through succeeding propagations.

The accompanying picture of the new variety shows the shape, color and relative size of the different parts of the plant, and the absence of thorns on flowering branches.

Observations of the new variety for the specific purpose of compiling data for this application were made on sunny days during the early part of September 1955, on plants growing outdoors in Fairport, N. Y.

The color terminology used in describing the new variety is in accordance to Ridgways Color Standard and Nomenclature (whenever plate number followed by the abbreviation Ridg. is given), Horticultural Color Chart of the British Color Council (whenever plant number followed by the abbreviation Hort. is given) and general meaning of Websters dictionary (when plate number is absent). The Horticultural Color Chart is used where Ridgways Color Standard does not quite describe the actual specimen, and vice versa.

The color of this new variety, like any other living plant, is effected by solar exposure, temperature, humidity, soil condition, relative duration of nocturnal and diurnal hours and other known and unknown factors, and, therefore, will undergo appreciable changes from time to time. But the changes in this variety is so slight that it shall not cross its general color boundary. The colors described in words in this specification of the new variety are those seen outdoors in good daylight by persons of normal eyesight. The colors on the accompanying drawing of this new variety are those seen in green house in good daylight by an artist with normal eyesight. Whenever the outdoor and greenhouse colors do not agree, the color as seen outdoors is the correct color of the new variety.
