Rose plant

Abstract

A new miniature rose variety of bright orange red coloring of good exhibition form and good substance.

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" (U.S. Plant Pat. No. 2,321) and the rose known as "Poker Chip" (U.S. Plant Pat. No. 4,582) as pollen parent. The varietal denomination of this new variety is "Savaweek".

Among the novel characteristics possessed by this new variety which distinguish it from its parent and all other varieties of which I am aware are its bright orange red flowers of good exhibition form and thick petals which open well in varied weather conditions. Asexual reproduction by budding of the new variety as performed in Essex County, Massachusetts, shows that the foregoing and other distinguishing characteristics come true to form and are established and transmitted through succeeding propagations.

The accompanying drawings show 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 Colour Chart (R.H.S.C.C.). The terminology used in color description herein refers to plate numbers in the aforementioned color chart, e.g., "34A" is plate 34A of The Royal Horticultural Society Colour Chart.
