ATTORNEYS 2,132 RQSE PLANT Herbert C. Swim, Ontario, and O. L. Weeks, Chino, Calih, assignors to The Collard-Pyle Company, West Grove, Pa., a corporation of Pennsylvania Filed Mar. 30, 1961, Ser. No. 99,649 1 Claim. (Cl. 47-61) The present invention relates to a new and distinct variety of rose plant of the grandiflora class, which was originated by us by crossing the variety Queen Elizabeth (Plant Patent No. 1,259) with the variety Blanche Mallerin (Plant Patent No. 594).

As the result of this breeding, we have created a new rose variety which is endowed with the following unique and desirable combination of characteristics which are outstanding therein and which distinguish it from its parents, as well as from all other varieties of which we are aware:

(1) A vigorous, tall and erect habit of plant growth, and a habit of producing long flower stems;

(2) Heavy and leathery foliage of grey-green cast and which is quite resistant to mildew;

(3) Large buds of from long-pointed to urn-shaped form;

(4) Broad petaled flowers;

(5) A distinctive and attractive white color tonality of the flowers; and

(6) Very smooth hips which become quite rounded at maturity and yellow in color.

In comparison with its seed parent Queen Elizabeth, our new variety does not have as thick growth; the foliage is smaller and not as abundant; the color of the foliage is grey-green, as distinguished from the more yellowish green of this parent; the buds and flowers are larger and the buds are much longer and more urn-shaped than those of this parent; and the buds and flowers arewhite or nearly white, as distinguished from the pink buds and flowers of the parent Queen Elizabeth."

As compared with the pollen parent Blanche Mallerinf? the new variety is very tall growing in habit, as distinguished from the more modest height of the plants of this parent; it is much more resistant to mildew under comparable conditions in southern California; the flower stems are much longer, but the plants are less thickly branched; and the flowers have fewer petals than those of Blanche Mallerin.

Asexual reproduction of our new rose variety by budding, as performed at Chino, 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 vegetative growth and flowers of our new variety in different stages of development and as depicted in color as nearlytrue as it is reasonably possible to make the same in a color illustration of this character.

The following is a detailed description of our new variety, with color terminology in accordance with the Nickerson Color Fan, published by Munsell Color Company, Inc., of Baltimore, Maryland, except where general color terms of ordinary dictionary significance are obvious:
