Ground cover rose plant named `Meipsidue`

Abstract

A new and distinct variety of ground cover rose plant (i.e., garden rose plant) is provided which forms in abundance on a substantially continuous basis attractive double blossoms that are Rose Bengal suffused with Cardinal Red. The overall coloration of the blossoms is velvet red. The vegetation is vigorous and the growth habit is flat and bushy. Attractive decorative medium green and glossy foliage is formed. Excellent disease resistance is exhibited. Additionally, the new variety grows very well on its own roots following asexual reproduction by cuttings.

Description

SUMMARY OF THE INVENTION

The new variety of ground cover Rosa hybrida 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) of the new variety was the product of the cross between the `Kormax` variety (non-patented in the United States) and the `Meibeluxen` variety (non-patented in the United States). The male parent (i.e., the pollen parent) of the new variety was the `Meineble` variety (U.S. Plant Pat. No. 7,116). The parentage of the new variety can be summarized as follows:

(`Kormax`.times.`Meibeluxen`).times.`Meineble`.

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 variety of ground cover rose plant of the present invention possesses the following combination of characteristics:

(a) Abundantly and substantially continuously forms attractive double blossoms that are Rose Bengal suffused with Cardinal Red,

(b) Exhibits a flat and bushy growth habit,

(c) Forms vigorous vegetation,

(d) Forms attractive decorative medium green and glossy foliage,

(e) Propagates well by cuttings, and

(f) Exhibits excellent disease resistance with respect to blackspot, downy mildew and powdery mildew.

The new variety reblooms in abundance.

The new variety of the present invention can be readily distinguished from its parent varieties. For instance, the `Kormax` variety forms a red single flower. The `Meibeluxen` variety forms a semi-double red flower, and the `Meineble` variety forms a red single flower with a white eye.

The new variety well meets the needs of the horticultural industry. It can be grown to advantage as an attractive ornamentation in parks, gardens, public areas, and residential landscapes. Accordingly, it is particularly well suited for growing in the landscape.

The characteristics of the new variety have been found to be homogeneous and stable and are strictly transmissible by asexual propagation at Le Cannet-des-Maures, Var France such as budding, grafting, and cuttage from one generation to another. The plant propagates well and grows very well on its own roots.

The new variety has been named the `Meipsidue` variety.
