Rose plant

Abstract

A grandiflora rose plant characterized by its unusual vigor and its brilliant, orange-red blooms.

Description

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 a rose seedling derived from a cross between the rose variety known as "Queen Elizabeth" (U.S. Plant Pat. No. 1,259) and the rose variety known as "Aztec" (U.S. Plant Pat. No. 1,648), and a seedling derived from a cross between the rose variety known as "Independence" (U.S. Plant Pat. No. 1,036) and the rose variety known as "Scarlet Knight" (U.S. Plant Pat. No. 2,692).

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) brilliant flaming orange-red coloring of the inner petal surfaces with a heavy smoky red on outer side of petals, (2) long lasting blooms holding their color well on the plant and after cutting, having petals that drop off cleanly on aging, and (3) a vigorous plant which is "winter hardy" with large waxed reddish green foliage extremely resistant to disease and adverse weather, and produces flowers borne singly and several together as sprays. Large strong canes are produced all summer long from base of plant. Asexual reproduction by budding of the new variety as performed in Chester County, Pa., 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 vigorous upright growing grandiflora rose with unusual brilliant fiery orange red coloring of iridescent quality. The flowers have excellent form and open well in varied weather conditions. The color of the blooms holds well and the appearance is not adversely affected by rain or heat. A strong rose attar fragrance complements the beauty of the flowers.

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., "45B" is plate 45B of the Royal Horticultural Society Color Chart.
