Application beceniber 26,'1933, Serial mlvoa'sss' 1 Claim. (01. 47-.61) .7 SepaZa-Serratd, curling back when bud' half The present invention relates to an improvement in white roses, particularly adapted to greenhouse culture for out flowers.

It is quite well known that the white rose has practically disappeared from greenhouses because none of the known varieties had the quality and steady production such as characterizes other roses of color and such as is necessary or desirable for greenhouse purposes.

The present rose has therefore been developed to fill the long desired demand, serving to bring back the white rose into favor as a cut flower. However, it is to be understood that this rose has also proved to be an improvement in and valuable addition to the line of garden roses.

The present rose, which has been asexually propagated and found to produce true to form, originated from a cross between unnamed seedlings issued from Briarcliff, Kaiserin Auguste Viktoria and Mrs. Herbert Stevens. The last named rose being a pure Tea rose, reinforces the Hybrid Tea strain and accounts for the unprecedented continuity and quantity of production which characterize this improvement rose.

Broadly speaking, the rose forming the subject matter of this application is considered novel in every particular, as to size, fragrance, form and length of stem required by the cut flower market.

Insofar as the bud is concerned, this is long pointed, the outer petals slowly recurve and the center of the bud remains tight for a very long period. The open bloom retains its form for days, thus enhancing its value as a cut flower. The production of commercial flowers is very heavy and steady. It is believed to be the finest white rose ever produced for forcing or garden use.

The above mentioned and other important characteristics are here listed for detail information: Parentage Seedling. Seed parent.Unnamed seeding of Briarcliff and Kaiserin A. Viktoria.

. acterized by its particular adaptation to greenhouse culture tor cut flowers where it produces evenly and continuously a quantity of blooms of high quality, thereby being of great value to the cut flower florists; by its large size, the fragrance of its bloom. its form, and length of stem, all as described, and the white color of its flower, as

shown.
