ROSE PLANT Filed Jan. 26, 1965 United States Patent O 2,624 ROSE PLANT Robert G. Jelly, Richmond, Ind., assignor to E. G. Hill C0., Inc., Richmond, Ind., a corporatien of Indiana Filed Jan. 26, 1965, Ser. No. 428,278 1 Ciaim. (Cl. Pit- 14) 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 '*Snowsong (Plant Patent No. 2,165) with the variety White Butterfly (Plant Patent No. 1,337).

The primary objective of this breeding was to produce a new rose variety which eliminates some of the problems which occur in producing and marketing the two parent varieties, and to develop a new white rose that would give i-mproved customer Satisfaction as cut fiowers. 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) A vigorous habit of growth;

(2) Excellent fiower productivity;

(3) Distinctive and attractive White fiowers of classic form which open from pointed buds;

(4) Good color retention throughout the year when grown in greenhouses; and

(5) Good tolerance to insecticides.

In comparison with its seed parent, Snowsong the white fiower color of the new variety is maintained more consistently throughout the year, the fiowers have a much nicer concentric opening form, and the plants eXhibit a higher degree of vigor.

As compared with its pollen parent, White Butterfly, the new variety eXhibits a much higher degree of tolerance to insecticides, while having some of the growth characteristics, as well as the excellent white fiower color, of this parent.

Asexual production of the new variety by grafting, as performed at Richmond, Indiana, and also by buddng, as performed at Livermore, California, shows that the fore going characteristics and distiuctions come true to form and are established and transmitted through succeeding propagations.

The accompanying drawing shows typical specimens of the vegetative growth and fiowers 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 color illustration of this Character.

The following is a detailed description of the new variety, With color terminology in accordance with Robert S. Wilsonis Horticultural Colour Chart (hereinafter abbreviated as (W)), and Nickerson Color Fan (hereinafter abbreviated as (N as indicated, except where general color terms of ordinary dictionary significance are obvious:
