Miniature rose plant named Benjim

Abstract

A new and unusual red and yellow bicolor miniature rose.

Description

SUMMARY OF THE INVENTION

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 variety known as "Rise'N Shine" (U.S. Plant Pat. No. 4,231) and as pollen parent the variety known as "Marina" (U.S. Plant Pat. No. 3,789). The varietal denomination of this new rose is "Benjim".

Among the novel characteristics possessed by this new variety which distinguishes it from its parents and all other varieties of which I am aware are its unusual red and yellow bicolored flowers in this class of rose. Flowers open well and retain bicolor effect as blooms age with red tones becoming pink and yellow coloring becoming near white. Asexual reproduction by propagation by cuttings 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.

BRIEF DESCRIPTION OF DRAWING

The accompanying drawing 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 PREFERRED EMBODIMENT

The following is a detailed description of my new variety, with color terminology in accordance with The Royal Horticultural Society Colour Chart (R.H.S.C.C.).
