USPP6560P - Miniature rose plant named `Swinger` - Google Patents

Abstract

A new and distinct variety of rose plant of the miniature rose class, which was originated by my crossing Rise n Shine as seed parent and Puppy Love as pollen parent; characterized by a strong growing upright winter-hardy plant producing medium golden yellow buds which open to a bright yellow flower and finishes to a golden ivory before fading.

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 "Rise n Shine" (U.S. Plant Pat. No. 4,231) and the rose known as "Puppy Love" (U.S. Plant Pat. No. 4,292) as pollen parent.

Among the novel characteristics possessed by this new variety which distinguished it from all other varieties of which I am aware are:

1. Well-formed blooms of medium-yellow coloring with ivory high-lights on velvety petals are borne primarily one to a stem on strong erect individual stems.

2. A strong, upright growing plant with much branching and excellent contrasting yellow-green foliage.

3. Produces attractive rose hips in late fall, not only lending additional color to the plant, but also mixing it useful as a seed parent.

Asexual reproduction by budding of the new variety as performed in Kent County, Md. shows that the foregoing and other distinguishing characteristics come true to form and are established and transmitted through succeeding propagation.

The new and improved rose variety which I have developed is an unusually well-formed medium to light yellow miniature rose with excellent flower and bud form and performs very well in planters and hanging baskets. The ivory highlights of each petal makes the plant very showy wherever a light, crisp color is useful in the garden or pot or terrace. The uniform coloration lasts well outdoors and maintains its color until the petals drop.

The accompanying drawing shows typical specimens of the vegetative growth and flowers of the new variety named "Swinger" (Jolswi), 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., "13-B" is plate 13-B of The Royal Horticultural Society Colour Chart.

Claims (1)

I claim:

1. A new and distinct variety of rose plant of the miniature rose class, substantially as shown and described, characterized particularly by flowers of unusually brilliant golden yellow opening to a clear golden ivory flower with deeper yellow tones at base of inner petal; flower form is excellent on this vigorous, upright growing plant.
