| Abstract: |
A white tea rose cultivar intended for greenhouse culture and cut flower production, the new plant being distinguished by its continuous and profuse production of large, clear white flowers borne on long, strong and sturdy stems and having a very excellent vase life. In greenhouse culture, this plant has a free branching, upright and vigorous growth habit with an abundant production of foliage of medium size. |
| Claim: |
I claim:
1. A new and distinct rose cultivar, substantially as herein shown and described, characterized by its profuse and continuous production of large flowers having clear white colorthroughout the body of each petal with the exception of a small amount of light yellow color at each petal base. |
| Description: |
BACKGROUND OF THE NEW PLANT
This new rose cultivar originated at Orland, Calif., as a sport of the variety "Lady Diana" (U.S. Plant Pat. No. 5,360) and was discovered by me in the summer of 1983. The size and clear white color of the flowers prompted me to reproduce thisnew plant by budding at Orland with very favorable results and subsequent propagation, also by budding, at Pleasanton, Calif., clearly demonstrated that the distinctive characteristics of this new plant would hold true from generation to generation andappeared to be firmly fixed.
DESCRIPTION OF THE DRAWINGS
My new variety of rose plant is illustrated by the accompanying full color photographic drawings which show a full face view of a newly opened flower in FIG. 1, a group of four stems illustrating the development of the blossom from newly openedbud to fully opened flower in FIG. 2, and in FIG. 3, specimens of wood, top and bottom views of leaves and a bud on which the sepals are just beginning to divide.
DESCRIPTION OF THE NEW PLANT
The following is a detailed description of my new variety of rose based upon observations of greenhouse plants grown at Orland, Calif., the color designations being made according to The R.H.S. Colour Chart published by The Royal HorticulturalSociety at London, England.

This new rose variety most nearly resembles "Lady Diana", U.S. Plant Pat. No. 5,360, from which it sported and generally it is not considered to be better than "Lady Diana". It has the same good growth characteristics except that the flower iswhite.
The most distinctive feature about this white rose is the manner in which it excels in comparison to other white hybrid teas in flower form, stem length, greenhouse production and vase life, which makes it ideal for the flower market from growerto the end consumer.
