R. BYRUM Plant Pat. 1,886

Dec. 8, 1959 ROSE PLANT Filed March 15, 1959 [N VEN TOR A T TOR VEYS nose PLANT Roy L. Byrum, Richmond, Ind., assignor to Joseph H. Hill Company, Richmond, Ind., a corporation of Indiana Application March 13, 1959, Serial No. 799,393 1 Claim. or. 47-61) The present invention relates to a new and distinct variety of rose plantof the large-flowered polyantha class, which was originated by me by crossing an unnamed and unpatented seedling identified in my breeding records as No. 52/40W, with the variety fWhite Butterfly (Plant Patent No. 1,337).

7 The primaryobjective of this breeding was to produce an improved white rose having both the good qualities of the variety White Butterfly, and flowers of greater petalage which are borne with a longer stretch on the stems. This objective was at least partially achieved, along with other improvements, as evidenced by the fact that the resulting new variety is of the floribunda type and is characterized by the following features which are outstanding therein and which represent a unique combination which distinguishes it from its parents, as well as from all other varieties of which I am aware:

r (1') Good bloom production suitable for the commercial production of cut flowers and better than the cut flower production of both the parent variety White Butterflyf and that of the variety White Bouquet (Plant Patent No.- 1,415) which-the present variety somewhat resembles;

, (2) A slow-opening flower habit, with consequent long-lasting flower qualities superior to those of the variety "-White Bouquet;

Propagation: Holds its distinguishing characteristics through succeeding propagations by bothgrafting and budding.

Flower Locality where grown and observed: Richmond, Indiana.

' Flowers borne: Both singly and in clusters, but can be (3) Greater flower petalage than that of the variety White Butterfly; and E (4) A- distinctive white general color tonality of the blooms.

Asexual reproduction of my new variety by both grafting and budding, as performed at Richmond, Indiana, and also by budding, as performed at West Grove, Pennsylvania, 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 my new variety, in diflerent 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 the new variety, with color terminology in accordance-with Robert F. Wilsons Horticultural Colour Chart (hereinafter abbreviated as Wilson), Ridgways Color Standards and Nomenclature (hereinafter abbreviated as Ridgway), and Kosters Color Guide (hereinafter abbreviated as Koster), except where general color terms of ordinary dictionary significance are obvious:
