ROSE PLANT Eugene S. Boerner, Newark, N. Y., assignor to Jackson & Perkins Company, Newark, N. Y., a corporation of New York Application November 5, 1954, Serial No. 467,249

1 Claim. (Cl. 47-61) The present invention relates to a new and distinct variety of rose plant of the large-flowered polyantha class, which was originated by me by crossing the variety Glacier (Plant Patent No. 1,025) with an unnamed and unpatented seedling of Pinocchio (Plant Patent No. 484).

The primary objective in making this cross was to produce a new variety of rose plant which bears white flowers and which is more vigorous than the parent variety Glacier, while at the same time, obtaining a white-flowered variety which is suitable for greenhouse growing for the production of cut flowers, which is something much needed in the class of White Floribundas. These objectives were fully achieved by crossing the variety Glacier with a seedling that is characterized by its great vigor and freedom of growth, with the result that the new variety is particularlycharacterized by its vigorous, free-growing and free-production habits under normal greenhouse conditions, which makes it very suitable for cut flower production, by the attractive shape of its half-open buds which are very adaptable for cut flowers, by the flat shape of its open flowers, resulting in almost hiding the stamens, which is a very interesting and different characteristic, and by the white color of its flowers comparable to the color of Glacier.

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