Description

Sept. 28, 1965 E. s. BOERNER Plant 5 ROSE PLANT Filed May 25, 1964 United States Patent Office Plant Pat. 2,553

Patented Sept. 28, 1965 The present invent-ion 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 Princess White (Plant Patent No. 1,540) with the variety known as White Queen (Plant Patent No. 1,762).

The primary objective of this breeding was to produce a new rose variety which is suitable for both outdoor cultivation and for out flower forcing, and which bears attractive White flowers of long-lasting qualities. This objective was fully 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:

(1) Excellent suitability for out flower forcing, with prolific production of attractive White flowers, espeoially when grown in the greenhouse for cut flower production;

(2) Good flower petalage, With the petals symmetrically arranged in a graceful manner, said petals being stiff and very resistant to rain and heat; and

(3) Very long-lasting qualities of the flowers both on the plant and as cut flowers.

Asexual reproduction of my new variety by budding, as performed at Newark, New York, and also at Pleasanton, California, shows that the aforementioned characteristics and distinctions come true to form and are established and transmitted through succeeding propagations.

The accompanying drawing shows typical specimens of the vegetable 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.
