Abstract

A novel rose variety of the hybrid tea class characterized by very large flowers of strong red coloring, borne singly on a strong stem as shown and described herein.

Description

The present invention relates to a new and distinct variety of rose plant of the hybrid tea class, which was originated by my crossing the rose variety known as "First Prize" as seed parent with the rose variety known as "Mr. Lincoln" 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: (1) very large flowers of dark red coloring which change to deep velvety purple upon aging, (2) long pointed buds opening into flowers of high center which are very long lasting on the plant, and (3) a very vigorous plant with very thick petals and abundant, large foliage of leathery texture. Asexual reproduction by budding of the new variety as performed in Kern County, Calif., shows that the foregoing and other distinguishing characteristics come true to form and are established and transmitted through succeeding propagations.

A main distinguishing feature of the new and improved rose variety is its unusual, large, dark red flowers which are produced on sturdy stems. In addition, this new variety does not possess the same susceptibility to diseases, such as "mildew", which is typical of many red roses.

Flowers of this new variety are usually borne singly, opening as high centered buds and maintaining the high center affect as it ages. Petals are very thick and have a velvety inside and are regularly arranged, however, the flowers are long lasting on the plant and after cutting. The large, abundant, thick, leathery foliage provides good support for these unusually large flowers.

The accompanying drawing shows typical specimens of the flowers and vegetative growth 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., "45B" is plate 45B of the Royal Horticultural Society Color Chart.
