Title: Rose plant

Description:
The present invention relates to a new and distinct variety of rose plant of the minature rose class, which was originated by my crossing as seed parent a seedling of the rose known as &#34;Gold Coin&#34; and an unknown 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) recurrent blooms of light yellow coloring, (2) high displaying high centered form singly and in sprays but with a form typical of hybrid tea plants, (3) plants which grow particularly well indoors under lights and outdoors in reduced-light conditions, and (4) plants which grow well on own roots due to strong tendency for root development. 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 light yellow coloring, bearing blooms of high centered, hybrid-tea like form both singly and in sprays. The usefulness of the plant is greatly enhanced by its ability to grow well under reduced-light, e.g. shade, conditions outdoors. However, one of its most valuable characteristics is its performance under lights which makes it a valuable greenhouse variety. The flowers last well on the plant and tend to lighten in color on aging. The plant itself is attractive in combining small, abundant foliage with well branching growth. Another especially desirable feature of this new variety is that it has virtually no thorns. 
    
    
     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., &#34;6D&#34; is plate 6D of the Royal Horticultural Society Color Chart.
