Rose plant

Abstract

A novel rose variety of the miniature rose class characterized by hybrid tea-like high centered blooms of orange-red to bronze-yellow coloring substantially as shown and described.

Description

The present invention relates to a new and distinct variety of rose plant of the miniature rose class, which was originated by my crossing as seed parent the rose known as "Zorina" and an unnamed seedling 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) strikingly colored blooms of unusually good high centered form borne primarily singly to a stem in a manner typical of hybrid tea plants, (2) flowers of good petalage displaying variable coloring under different lighting availability but featuring an orange-red to bronze blending with cream and yellow tones, and (3) a well branched, compact, upright growing plant. Asexual reproduction by budding of the new variety as performed in Essex County, Mass., 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 miniature rose of orange-red to bronze blending singly-borne blooms of high centered, hybrid-tea like form are delightfully displayed on an upright growing compact plant. The flowers are unusually well formed, for a miniature rose and are of a novel coloring, varying under different light conditions, but generally producing an overall tonality reminiscent of a desert sunset coloring. The petals open sharply quilled forming star like points. The plant itself is attractive in combining medium, abundant foliage with well branching growth.

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 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., "40A" is plate 40A of the Royal Horticultural Society Color Chart.
