| Abstract: |
A new rose plant of the shrub class producing clusters of red flowers. |
| Claim: |
I claim:
1. A new and distinct variety of rose plant of the shrub rose class, substantially as shown and described. |
| Description: |
SUMMARY OF THEINVENTION
The present invention relates to a new and distinct variety of rose plant of the shrub rose class which was originated by my crossing as seed parent the variety known as `Gitte` and as pollen parent an unnamed and unpatented seedling of mycreation. The varietal denomination of this new rose is `Twoadvance` and its commercial name is `All That Jazz`.
Among the novel characteristics possessed by this new variety which distinguishes it from its parents and all other varieties of which I am aware are its attractive red flowers borne on a shrub size plant particularly suitable for use in gardens. Flowers open well and hold their coloring as blooms age. The new variety is also characterized by its health, vigor and flower production as well as its outstanding resistance to mildew, black spot, rust and botrytis.
Asexual reproduction by budding and rooting of cuttings of the new variety as performed in Glenn County, Calif. and Kern County, Calif., shows that the foregoing and other distinguishing characteristics come true to form and are established andtransmitted through succeeding propagations.
BRIEF DESCRIPTION OF ILLUSTRATION
The accompanying illustration shows typical specimens of the vegetative growth and flowers of the new variety in different stages of development and depicted in color as nearly true as it is reasonably possible to make the same in a colorillustration of this character.
DESCRIPTION OF THE NEW VARIETY
`Twoadvance` is an unusually fine shrub rose of red flower coloration. It is especially well suited for landscape use and growing outdoor in gardens. The variety blooms freely under natural growing conditions. The foliage is dark green, semileathery and holly-like.
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 color description herein refers to plate numbers in theaforementioned color chart.
