ROSE PLANT Filed June 13, 1963 United States Patent() Filed June 13, 1963, Ser. No. 287,729 1 Claim. (Cl. Plt.18)

. 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 The Optimist (U.S. Plant Patent No. 1,5 33.) with the variety known as Queen Elizabeth (U.S. Plant Patent No. 1,259).

As the result of this breeding, I have produced a new and improved rose variety which is especially suitable for the production of cut flowers grown under glass, and which is distinguished from its parents, as well as from all other varieties of which I am aware, as evidenced by the following unique combination of characteristics which are outstanding therein: I (l) A vigorous and upright habit of growth;

(2) Large, dark green foliag (3) Freedom from thorns on the flower stems;

(4) A good opening habit of the flower buds when out in the bud state and kept in water;

(5) Good production of well-shaped double flowers borne on long and strong stems;

(6) Distinctive, attractive and healthy pink flowers; and

(7) Special suitability for out flower production in greenhouses, as well as good suitability for outdoor flower production under warm and dry climatic conditions.

The distinctions of the new variety from its parents, which are well known, will be obvious from the following description and the accompanying illustrations, without the need of a specific comparison.

In some respects, my new rose variety appears to be slightly similar to the variety recently originated in Europe and known as Romantics. (unpatented),.but my new variety is different in its habit of growth, is better for out flower production, and produces healthier flowers. Moreover, the variety Romantica has very small thorns on its flower stems, while the flower stems of my new variety are free of thorns. The leaves of the new variety are more oblong in shape than those of R0- mantica, and a comparison of the reproductive organs shows that my new variety has a much smaller ovary.

Asexual reproduction of the new variety by both graft ing and budding, as performed by me at Hazerswoude, Holland, 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 diflferent 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 Wilson Color Chart as prepared in collaboration with the Royal Horticultural Society, except where general color terms of ordinary dictionary significance are obvious:
