USPP7979P - Grandiflora rose plant named Twoloy - Google Patents

Abstract

A new grandiflora rose plant producing pink flowers.

Description

SUMMARY OF THE INVENTION

The present invention relates to a new and distinct variety of rose plant of the grandiflora rose class which was originated by my crossing as seed parent the variety known as `Brion` and as pollen parent an unnamed and unpatented seedling of my creation. The varietal denomination of this new rose is `Twoloy`.

Among the novel characteristics possessed by this new variety which distinguished it from its parents and all other varieties of which I am aware are its clusters of pink flowers borne on a plant particularly suitable for use in gardens. Flowers open well and are long lasting on the plant and after cutting. The new variety is also characterized by its health, vigor and flower production.

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 and transmitted through succeeding propagations.

BRIEF DESCRIPTION OF ILLUSTRATIONS

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 color illustration of this character.

DESCRIPTION OF THE NEW VARIETY

`Twoloy` is an unusually fine grandiflora rose of pink flower coloration. It is especially well suited for growing outdoor in gardens. The new variety blooms freely and continuously under natural growing conditions on a tall, upright plant in clusters of up to twelve large blooms. `Twoloy` also does well on its own roots.

The following is a detailed description on 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 the aforementioned color chart.
