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 "Arthur Bell" and the rose known as "Yellow Jewel" 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) beautiful yellow colored blooms of good form borne primarily singly to a stem in a manner typical of hybrid tea plants and also blooming on long basal canes, (2) flowers of relatively strong sweet fragrance and (3) a well branched, very compact, growing plant normally with glossy sculptured foliage similar to its parent, the floribunda Arthur Bell. 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 strong yellow coloring, singly-borne blooms of high centered, hybrid-tea like form are delightfully displayed on an extremely compact plant of attractive foliage. The flowers are unusually well formed, for a yellow miniature rose and the plant displays flowers of deep yellow general tonality since the blooms lighten only slightly upon aging. An additional attractive feature is the unusually strong fragrance for a miniature rose.

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., "15A" is plate 15A of the Royal Horticultural Society Color Chart.
