A new miniature rose variety of azalea pink flower coloring.

Skip to: Description  ·  Claims  · Patent History  ·  Patent History

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 "Tom Brown" and the rose known as "Over the Rainbow" (U.S. Plant Pat. No. 3,472) as pollen parent. The denomination of the new rose is "Minoco".

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 attractive flowers of good form and azalea pink coloring and unusual combination of inner petals rolling downward and outer petals reflexing to points. The flower coloring is constant and substantially unfading. Asexual reproduction by budding of the new variety as performed in Dallas County, Tex., shows that the foregoing and other distinguishing characteristics come true to form and are established and transmitted through succeeding propagations.

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 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., "13B" is plate 13B of The Royal Horticultural Society Colour Chart.
