Abstract

A new hybrid tea rose variety of brilliant red coloring, and occasional petal blackening which is substantially non-fading and long lasting on the plant and as a cut flower.

Description

The present invention relates to a new and distinct variety of rose plant of the hybrid tea rose class, which was originated by my crossing as seed parent the rose known as "Mister Lincoln" and the rose known as "Mexicana" as pollen parent.

Among the novel characteristics possessed by this new variety which distinguish it from its parents and all other varieties of which I am aware are vibrant, substantially non-fading, red colored flowers which start as dark, almost black red buds and a vigorous plant with attractive green foliage. Open blooms are especially attractive and remain non-fading or bluing and are long lasting on the plant and when cut. Asexual reproduction by budding of the new variety as performed in San Bernardino County, Calif., shows that the foregoing and other distinguishing characteristics come true to form and are established and transmitted through succeeding propagations.

The new and improved rose variety which I have developed is an unusually fine red hybrid tea rose of substantial petalage and which does not "blue" upon aging.

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 a color illustration of this character.

The following is a detailed description of my new variety, with color terminology in accordance with the Royal Horticultural Society Color Chart (RHSCC). The terminology used in color description herein refers to plate numbers in the aforementioned color chart, e.g., "46A" is plate 46A of the Royal Horticultural Society Color Chart.
