A white rose cultivar most suitable for greenhouse culture for cut flower production, the new plant being distinguished by its abundant and continuous production of small white flowers borne on long, moderately strong stems, its extraordinary vigor as a greenhouse rose which permits a greater spacing of the plants and an improvement in the economics of rose plant costs, and by the good vase life of its flowers.
A new and distinct variety of rose plant substantially as herein shown and described, characterized by its abundant and continuous production of white blossoms of relative small size but excellent form, borne on long, moderately strong stems, and by its extraordinary vigor for a greenhouse rose.

This new variety of rose plant originated at Redwood City, Calif., as a seedling resulting from my crossing of an undisseminated seedling, identified as number 9-67-PS in my breeding stock, with the cultivar Bridal Pink (U.S. Plant Pat. No. 2,851) as the pollen parent in the Spring of 1969. My object was to improve the keeping quality of Bridal Pink and to improve the stem length of the seed parent and the new variety, although white and not the pink of its parents, has the characteristics that I was seeking. The first flowering of this new rose variety occurred in 1970 and because of its distinctiveness over its parents, I reproduced the plant by grafting to test its retention of its distinguishing characteristics. Propagation of this new plant through successive generations, by grafting at Richmond, Ind., and by budding at Livermore, Calif., has demonstrated that the distinctive characteristics of the new variety hold true from generation to generation and appear to be firmly fixed.
My new variety of white rose plant is illustrated by the accompanying photographic drawing which shows, in full color, face views of a newly opened flower and a mature blossom, specimens of buds in various stages of opening, typical specimens of leaves, a specimen of young wood with leaves, and a specimen of the mature wood. The colors shown are believed to be as true as is reasonably possible to be had through conventional photographic procedures.
The following is a detailed description of my new variety of white rose plant based upon observations of greenhouse plants made at Richmond, Ind., the color designations being made according to the Horticultural Colour Chart (HCC) produced by Robert S. Wilson in collaboration with the British Color Council and according to the Royal Horticultural Society Colour Chart (RHS), both having been published by The Royal Horticultural Society of London, England.
Origin: Seedling identified as No. 72-72-WS.
