Abstract

A new and distinct variety of shrub rose plant is provided which forms in abundance on a nearly continuous basis in clusters attractive double cup-shaped fragrant blossoms which clean well that are bright peach in coloration. The vegetation is vigorous and a spreading round cover growth habit with procumbent vegetation is displayed. Attractive dark green foliage with a glossy finish is formed. The plant develops well regardless of the mode of asexual propagation. Excellent disease resistance with respect to Black Spot, Powdery Mildew, and Rust is displayed. The new variety is particularly well suited for providing attractive ornamentation in the landscape as a mass planting or when grown in containers.

Description

Botanical/commercial classification: Rosa hybrida/Shrub Rose Plant.

Varietal denomination: cv. Meiggili.

SUMMARY OF THE INVENTION

The new variety of Rosa hybrida shrub rose plant of the present invention was created by artificial pollination wherein two parents were crossed which previously had been studied in the hope that they would contribute the desired characteristics. The female parent (i.e., the seed parent) was the product of the cross of the ‘Ruimired’ variety (U.S. Plant Pat. No. 5,770) and the ‘Paul Crampel’ variety (non-patented in the United States). The male parent (i.e., the pollen parent) of the new variety was the product of the cross of the ‘Korimro’ variety (non-patented in the United States) and the ‘Lady Gay’ variety (non-patented in the United States). The parentage of the new variety can be summarized as follows:
(‘Ruimired’×‘Paul Crampel’)×(‘Korimro’×‘Lady Gay’).

The seeds resulting from the above pollination were sown and small plants were obtained which were physically and biologically different from each other. Selective study resulted in the identification of a single plant of the new variety.

It was found that the new shrub rose plant of the present invention possesses the following combination of characteristics:

- (a) abundantly forms in clusters attractive double cup-shaped fragrant blossoms which clean well that are bright peach in coloration,
- (b) exhibits a spreading ground cover growth habit with procumbent vegetation,
- (c) forms vigorous vegetation,
- (d) forms attractive dark green foliage with a glossy finish that contrasts well with the blossom coloration,
- (e) is highly resistant to Black Spot, Powdery Mildew, and Rust, and
- (f) is particularly well suited for providing attractive ornamentation in the landscape as a mass planting or when grown in containers.

The plant develops well following asexual propagation regardless of the mode of asexual propagation.

The new variety well meets the needs of the horticultural industry. It can be grown to advantage as ornamentation in parks, gardens, public areas, and in residential settings. The new variety is particularly well suited for growing in smaller areas as a ground cover, as a mass planting in a larger area, and in containers.

The new variety of the present invention also can be readily distinguished from its ancestors. More specifically, the ‘Ruimired’ variety forms dark red blossoms having no fragrance, the ‘Paul Crampel’ variety forms deep orange-scarlet blossoms, the ‘Korimro’ variety forms single light pink blossoms, and the ‘Lady Gay’ variety forms dissimilar orange-pink blossoms that tend to appear only once per season.

Additionally, the new variety can be readily distinguished from other similar rose varieties, such as the ‘Meilmera’ variety (U.S. Plant Pat. No. 10,002) and the ‘Meidarin’ variety (U.S. Plant Pat. No. 13,291). The ‘Meilmera’ variety has a similar growth habit, but displays white blossoms and is considerably less hardy. The ‘Meidrain’ variety also displays a similar growth habit, but displays vibrant orange blossoms and also is considerably less hardy.

The characteristics of the new variety have been found at Waso, Calif. U.S.A., and near West Grove, Pa., U.S.A., to be homogeneous and stable and to be strictly transmissible by asexual propagation, such as budding, grafting, and the rooting of cuttings from one generation to another. The new variety reproduces true to type by such asexual propagation.

The new variety has been named ‘Meiggili,’ and is being marketed under the PEACH DRIFT trademark.

BRIEF DESCRIPTION OF THE PHOTOGRAPHS

The accompanying photographs show, as nearly true as it is reasonably possible to make the same in color illustrations of this character, typical flowering plants of the new variety. The illustrated rose plants of the new variety were approximately three years of age and were observed during June while growing outdoors on ‘Dr. Huey’ rootstock near West Grove, Pa., U.S.A.

FIG. 1 shows a specimen of a flowering plant of the new variety wherein the spreading growth habit with procumbent vegetation is illustrated.

FIG. 2 shows a closer view where the buds, blossoms in various stages of development, and glossy dark green foliage are illustrated.

DETAILED DESCRIPTION

The chart used in the identification of colors is that of The Royal Horticultural Society (R.H.S. Colour Chart), London, England. The description is based on the observation of three-year-old specimens of the new variety during June while growing outdoors on ‘Dr. Huey’ rootstock near West Grove, Pa., U.S.A.
