| Description: |
BACKGROUND OF THE NEW PLANT
This new plant originated as a seedling of an unknown hybrid of unknown parentage growing among a collection of miscellaneous rose plants maintained for breeding purposes. This plant caught my attention because of its overall bright red color,its relatively large size on strong upright stems of a plant having good foliage and an apparently vigorous growth habit. Because of those characteristics, I propagated this seedling at Pleasanton, Calif. by budding with very satisfactory resultswhereupon I continued propagating this plant in the same manner through several generations in greenhouse at Pleasanton which demonstrated conclusively that the novel characteristics of the discovery seedling would hold true from generation to generationand appeared to be firmly fixed.
DESCRIPTION OF THE DRAWING
This new rose plant is illustrated by the accompanying full color photographic drawing which shows a group of the flowers in various stages of development, the colors shown being as nearly true to that herein specified as is reasonably possibleto obtain by conventional photographic procedures.
DESCRIPTION OF THE NEW VARIETY
