A TTORNEYS SIIMQS Unite 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 Peace (Plant Patent No. 591) with the variety Yellow Perfection (Plant Patent No. 1,083).

The parent variety Peace is a well-known and ex- .tremely popular garden rose, but it will not stretc sufliciently to produce cut flowers of a suitable length, and hence, is'not satisfactory or profitable for the commercial production of cut flowers grown under glass. Accordingly, it was the primary objective of this breed ing to produce a new rose variety which bears blooms of a color comparable to the blooms of Peace, but which. is more suitable for out flower forcing than either ,of the aforementioned parent varieties. It was a further objective to attain a new rose variety of the type noted above, but which produces buds of a longer form than the normal buds of Peace, and also greater flower petalage than that of the parent variety Yellow Perfection. These objectives were fully achieved, along with other improvements, as evidenced by the following unique combination of features 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:

atent (1) A more glossy foliage than that of Yellow Perfection;

(2) Longer buds than those of Peace;

(3) A habit of bearing flowers on strong stems of a length suitable for out flowers;

(4) Greater flower petalage than that of Yellow Perfection; and

(5) A general color tonality of the flowers which may -be best described as solid Straw Yellow in the newly-opened flowers, changing .to Naples Yellow as the flowers age, without any red or pink colorationexcept in the tight bud stage, and with no' appreciable change in the flower color during different seasons.

Asexual reproduction of my .new variety by grafting, as performed at Richmond,'lndiana, 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 the new variety in different stages of development and is 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 my new variety, with color terminology in accordance with Robert F.
