ROSE PLANT Filed Jan. 5, 1956 United States Patent ROSE PLANT Louis Lens, Wavre-Notre-Dame, Belgium, assignor to Jackson & Perkins Company, Newark, N. Y., a corporation of New York Application January 5, 1956, Serial No. 557,617

1 Claim. (Cl. 47-61) 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 Lady Sylvia (unpatented) with an unnamed and unpatented seedling derived from Virgo (unpatented) White Briarclifi (Plant Patent No. 108).

The primary objective of this breeding was to produce a new white rose variety having improved heavy flower petals and which is suitable for both cut flower and out-of-door use. This objective was fully achieved, along with other characteristics representing a unique combination of features in a rose of this class, as evidenced by the following characteristics which are predominant in the new variety:

(1) The upright and firm plant growth;

(2) The heavy, stilt petals of the flowers, which are quite unusual in white hybrid tea varieties;

(3) The floriferousness of the variety and the suitability of the flowers for both cut flower and out-of-door use; and

(4) The distinctive and attractive white color of the flowers.

The foregoing characteristics definitely differentiate my new variety from its parents, as well as from all other varieties of its class of which I am aware, and asexual reproduction of the new variety by budding, as performed at Newark, New York, U. S. A., and also at Pleasanton, California, U. S. A., 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 vegitative 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.
