| Abstract: |
A new rose variety of the Hybrid Tea class characterized by having large well formed red flowers on a bush with extremely glossy foliage and excellent disease resistance. |
| Claim: |
I claim:
1. A new and distinct variety of rose plant of the Hybrid Tea class, substantially as herein shown and described. |
| Description: |
The presentinvention relates to a new and distinctive variety of rose plant of the Hybrid Tea class, which was originated by my crossing `Pink Favorite` (U.S. Plant Pat. No. 1,523) as the seed parent with `Simon Bolivar` (U.S. Plant Pat. No. 2,705) as thepollen parent.
Among the novel characteristics possessed by the new variety which distinguish it from its:
(a) Parents and all other varieties of which I am aware are:
(1) A plant which has foliage of remarkably high gloss;
(2) A large red flower showing magenta hues with aging; and
(3) A vigorous plant of medium height.
(b)
Seed parent.--Pink flowers; tall.
Pollen parent.--Orange/red flowers; matte foliage.
Asexual reproduction of the new rose variety by budding, as performed at Tulare, Calif. shows that the aforementioned and all other distinctive characteristics come true to form and are established and transmitted through succeedingpropagations.
The accompanying drawing shows typical specimens of the vegetative growth and flowers of the new variety in different stages of development and as depicted in color as nearly true as it is reasonably possible to make the same in acolor illustration of this character.
The following is a detailed description of my new variety, with color terminology in accordance with The Royal Horticultural Society Colour Chart (R.H.S.C.C.). The terminology used in the color descriptionherein refers to plate numbers in the aforementioned color chart, e.g. "53A" is plate "53A" of The Royal Horticultural Society Colour Chart.
Parentage:
Seed parent.--Pink Favorite`.
Pollen parent.--`Simon Bolivar`.
Class: Hybrid Tea.
The following observations are made of specimens grown outdoors in Contra Costa County, Calif., in the month of September.
