Seedling rose No. 76-23R

Abstract

A red grandiflora rose for greenhouse culture and the production of cut flowers, this new variety being characterized by its free, vigorous, upright and much branched growth habit with free and abundant continuous production of flowers in greenhouse; a particular distinctiveness of this new variety being its attractive, long pointed bud at cutting stage, its excellent vase life as a cut flower and its abundant production of foliage comprising leaves of relatively large size.

Description

BACKGROUND OF THE NEW PLANT

This new rose plant originated as a seedling resulting from crossings of unnamed and unpatented seedlings made by me in the Spring of 1974 at Richmond, Ind., with the object of producing a variety with medium sized blooms carried on longer than average stems for a good grandiflora. The flowers appeared in the Fall of 1975 and this particular plant was selected by me because of its more vigorous growth with sturdier, longer stems and more attractive pointed buds than its seed parent, and because of its more profuse and upright growing habits than the habits of its pollen parent. Extensive testing of this new plant through repeated propagations under my direction, by grafting at Richmond, Ind., and by budding at Hamilton City, Calif., has demonstrated that the attractive and distinctive characteristics of this new plant hold true from generation to generation and appear to be firmly fixed.

DESCRIPTION OF THE DRAWING

My new rose plant is illustrated by the accompanying photographic drawing which, in full color, shows a face view of a newly opened flower, buds in two stages of opening, specimens of inside, intermediate and outside petals of the opened bud, specimens of the inside, intermediate and outside petals of the fully opened flower, and specimens of foliage and wood, the color rendition of this drawing being as nearly true as is reasonably possible to obtain by conventional photographic procedures.

This new rose variety is in general similar to "Mary DeVor" (U.S. Plant Pat. No. 2,838). It is similar in stem length; however, the bud and color of the open bloom is brighter throughout the entire year. Also, the new plant is particularly distinguished by its attractive, long pointed bud at cutting stage, its sturdy, upright and vigorous growth habit and prolific production of flowers. This new plant has no special cultural requirements and its foliage does not sunburn in greenhouse.

Claims

1. A new and distinct variety of rose plant, substantially as herein shown and described, characterized by its abundant and continuous production of flowers, its free and vigorous growth habit and its long pointed bud at cutting stage.
