United States Patent 2,333 R0E PLANT Luciano Moro, San Remo, italy, assignor to Carlton Rose Nurseries, Carlton, Oreg, a corporation of Oregon Filed Lian. it), 1953, Sen No. 254L725 1 Claim. (Cl. Pit-2i) 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 known as Volcano (US. Plant Patent No. 951) with the variety Rouge Meilland, known in the United States as Happiness (US. Plant Patent No. 911).

The primary objective of this breeding was to produce an improved rose variety, and more particularly superior to the rose variety Happiness which is probably the top premium red rose that is grown under glass in the United States at the present time for the commercial production of cut flowers, but the flowers of which have a tendency to turn dark in color during the short, dark days of winter, as well as a tendency to reduce its flower productivity during the winter season as the result of blind wood which does not bloom at that time of year under glass. My new variety fully overcomes these problems, and, accordingly, the aforementioned objectives have been achieved, along with other desirable improvements, as evidenced by the following unique combination of characteristics which are outstanding in the new variety and which distinguish it from its parents, as well as from all other varieties of which I am aware:

(l) A vigorous habit of growth which is maintained during the winter season and which is superior to the vigor of both parent varieties;

(2) A prolific and relatively rapid production of com merically salable flowers of excellent quality and which constitutes an important asset to the commercial grower during the winter season when the cut flower market is best and more profitable;

(3) A distinctive, attractive and brilliant red color of the flowers, said color being slightly li hter at all times than the color of the flowers of either parent variety which tend to darken considerably during the short, dark days of winter when grown under glass;

(4) A uniform color of the flower petals and prolonged retention of the flower color both on the bush and when cut for cut flower production; and

(5) Good flower petalage which is considerably greater than the petalage of the flowers of either parent variety.

In comparison with the parent varieties, my new variety has a desirable feature resulting from a slightly lighter flower color than the flower color of either parent variety, and the color of the new variety is retained throughout the year; the flowers have many more petals and the plants will produce more salable flowers in a shorter eriod of time than either of the parent varieties, which is a very important factor in the highly competitive field of commercial cut flower production; and the flowers of the new variety are loose enough so that they will open to full maturity under adverse conditions, with consequent production of top quality blooms at all times, and retention of full productive vigor attributable to far less blind wood than is characteristic of either parent variety.

Asexual reproduction of my new Variety by budding in San Remo, Italy, as well as under glass at Hillsboro, Oregon, U.S.A., and in the fields at Carlton and Gaston, Oregon, U.S.A., shows that the foregoing 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 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 issued by the British Colour Council in collaboration with The Royal Horticultural Society, except where general color terms of ordinary dictionary significance are obvious:
