| Abstract: |
A novel grandiflora rose plant characterized by a vigorous, upright growth habit, many cherry and white bicolored flowers with no fragrance, borne in long-stemmed clusters, its many long, abundant thorns, and resistance to mildew and blackspot. |
| Claim: |
I claim:
1. A new and distinct variety of rose plant of the grandiflora class, substantially as shown and described herein, characterized particularly as to novelty by the unique combination ofits upright, vigorous growth with many blooms borne in long-stemmed clusters, its cherry and white bicolored flowers with no fragrance, its heavy long, abundant thorns and its dark brown new foliage. |
| Description: |
BACKGROUND OF THE INVENTION
The present invention relates to a new and distinct variety of rose plant of the grandiflora class which was originated by me by crossing an unnamed variety with pollen of the variety Redgold, U.S. Plant Pat. No. 3,006.
The primary objective of this breeding was to produce a new rose variety of the grandiflora class bearing multicolored or bicolored blooms. This objective was substantially achieved as evidenced by the following unique combination ofcharacteristics which are outstanding in the new variety and which distinguish it from its parents as well as from all other varieties of which I am aware:
1. An upright, vigorous plant with a strong tendency to produce blooms in long-stemmed clusters on main canes and small clusters on lateral branches.
2. Flower color essentially cherry red with a white reverse.
3. Little or no fragrance.
4. Very dark Garnette Brown new foliage and stems.
5. Many long, nearly straight thorns.
Asexual reproduction of this new cultivar by budding as performed at Wasco Calif., shows that the foregoing characteristics and distinctions come true to form and are established and transmitted through succeeding propagations.
Theaccompanying illustration shows typical specimens of the vegetative growth and flowers of this new cultivar in different stages of development, depicted in color as nearly true as it is reasonably possible to make the same in a color illustration of thischaracter.
The following is a detailed description of my new rose cultivar with color terminology in accordance with Wilson's Horticultural Color Chart, except where ordinary dictionary significance of color is indicated.
Parentage: Seedling.
Seed Parent.--Unnamed variety.

Base of petals, upper side: large triangular area of Primrose Yellow (601). Reverse side: large triangular area ofPrimrose Yellow (601/2). General tonality from a distance -- cherry on upper side, with white reverse.

Reproductive Parts:
Stamens, anthers.--Large. Color: yellow. Arrangement: regular around styles.
Filaments.--Yellow.
Pollen.--Lemon yellow.
Styles.--Color: pale yellow, near Primrose Yellow (601/3).
Stigmas.--Color: similar to styles.
