USPP24071P3 - Floribunda rose plant named ‘Meinoplius’ - Google Patents

Abstract

A new and distinct variety of Floribunda rose plant is provided that abundantly forms on a substantially continuous basis attractive double red-purple blossoms having a lighter coloration on the under surface. The vegetation is strong and a compact bushy growth habit is displayed. Exceptional resistance to common rose diseases has been observed. The plant is well suited for providing distinctive attractive ornamentation in the landscape.

Description

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

Varietal denomination: Cv. Meinoplius.

SUMMARY OF THE INVENTION

The new variety of Rosa hybrida Floribunda rose plant was created in France 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 ‘Meihatoil’ variety (non-patented in the United States). The male parent (i.e., the pollen parent) was the product of the ‘Korimro’ variety (non-patented in the United States). The parentage of the new variety can be summarized as follows:
‘Meihatoil’בKorimro’.

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 Floribunda rose plant of the present invention:

• • (a) forms strong vegetation,
  • (b) forms a bushy compact growth habit,
  • (c) forms in abundance on a substantially continuous basis attractive small double red-purple blossoms having a lighter coloration on the under surface,
  • (d) displays attractive green foliage with a glossy aspect on the upper surface,
  • (e) exhibits exceptional resistance to common rose diseases, and
  • (g) is well suited for providing distinctive attractive ornamentation in the landscape.

The new variety well meets the needs of the horticultural industry and can be grown to advantage in parks and gardens. Blossoming commonly commences early in the season.

The new variety can be readily distinguished from its ancestors. For instance, ‘Meihatoil’ variety forms dissimilar yellow blossoms. The ‘Korimro’ variety forms dissimilar single blossoms and lacks a propensity for repeat blooming.

The new variety additionally can be readily distinguished from the ‘Meidomonac’ variety (U.S. Plant Pat. No. 5,105) and the ‘Meisylpho’ variety (non-patented in the United States). The ‘Meidomonac’ variety displays a considerably taller growth habit and lacks a petal color change on the under surface. The ‘Meisylpho’ variety forms larger flowers and also lacks a petal color change on the under surface.

The new variety has been found to undergo asexual propagation at Le Cannet des Maures, Var, France, by a number of routes, including budding, grafting, and the use of cuttings. The plant grows well on its own roots. Such asexual propagation by the above-mentioned techniques has shown that the characteristics of the new variety are stable and are strictly transmissible by such asexual propagation from one generation to another. Accordingly, the new variety undergoes asexual propagation in a true-to-type manner.

The new variety has been named ‘Meinoplius’, and sometimes has been identified as ‘Lovely Pink’.

DETAILED BOTANICAL DESCRIPTION

The chart used in the identification of the colors is that of The Royal Horticultural Society (R.H.S. Colour Chart-1995 Edition or equivalent) except where ordinary color terms are utilized. Such common color terms are to be accorded their customary dictionary significance. The description is based upon the observation during May of plants of the new variety at an age of approximately one year while growing on their own roots outdoors at Le Cannet des Maures, Var, France.
