[N VE/VTOR ATTORNEYS United States 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 Snow White (Plant Patent No. 348) with an unnamed and unpatented seedling of Snow White.

The primary objective of this breeding was to produce a new rose variety from which there has been eliminated some of the faults of white rose varieties presently found in commercial flor'iculture. Thi objective was achieved in many respects, 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) An upright habit of plant growth;

( 2) Extremely attractive and glossy foliage;

(3) Good flower productivity;

(4) A high-centered and substantially perfect bud form;

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

(6) Good petal texture; and

(7) Good keeping qualities of the flowers.

In comparison with its seed parent Snow White, my new variety bears foliage which is much glossier, is more upright in its habit of growth, and bears more perfectly formed high-centered buds.

As compared with its unnamed seedling pollen parent, the new variety produces more flowers, the flowers have better keeping qualities, and the flower petals have better texture.

A sexual reproduction of the new variety by both grafting and budding, as performed at Richmond, Indiana, and at Livermore, 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 vegetative growth and flowers of my new variety in different stages of development 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 Ridgways Color Standards and Nomenclature (hereinafter abbreviated as R) and Robert S. Wilsons Horticultural Colour Chart (hereinafter abbreviated as W), as indicated, except where general color terms of ordinary dictionary significance are obvious.
