Rosa hybrida/Floribunda Rose Plant
cv. Meipeporia
The new variety of Rosa hybrida Floribunda rose plant 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 ‘Meinoiral’ variety (non-patented in the United States) and ‘Kortikel’ variety (non-patented in the United States). The male parent (i.e., the pollen parent) was the ‘Radrazz’ variety (U.S. Plant Pat. No. 11,836). The ‘Kortikel’ variety is marketed under the GOLDEN HOLSTEIN trademark and the ‘Radrazz’ variety is marketed under the KNOCK OUT trademark.
The parentage of the new variety can be summarized as follows:
(‘Meinoiral’בKortikel’)בRadrazz’.
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) displays a bushy growth habit with strong vegetation,
(b) forms in abundance on a substantially continuous basis attractive dark red double blossoms commonly with a particularly impressive blooming propensity in the autumn,
(c) exhibits very dense dark green foliage with a matte finish on the upper surface,
(d) exhibits very good tolerance to disease, particularly with respect to Botrytis, and
(e) is well suited for providing attractive ornamentation in parks and gardens.
The blooming tends to commence medium in the season, during observations to date.
The new variety well meets the needs of the horticultural industry and can be grown to advantage where attractive ornamentation is to be provided.
The new variety can be readily distinguished from its ancestors. For instance, the ‘Meinoiral’ variety forms dissimilar blossoms having a medium pink coloration. The ‘Kortikel’ variety forms dissimilar blossoms having a yellow coloration. The ‘Radrazz’ variety forms dissimilar red blossoms having a substantially lesser number of petals (e.g., approximately 10 petals).
The new variety has been found to undergo asexual propagation in France by a number of routes, including budding, grafting, and the use of cuttings. Asexual propagation by the above-mentioned techniques at Le Cannet des Maures, Var, France, 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 ‘Meipeporia’.
The accompanying photograph shows as nearly true as it is reasonably possible to make the same, in a color illustration of this character, typical specimens of the plant parts of the new variety. The rose plants of the new variety were approximately 1½ years of age and were observed during July while growing outdoors on their own roots at Le Cannet des Maures, Var, France. Standard comparative color information is included at the bottom of the photograph.

FIG. 2—illustrates a specimen of a floral bud at the initial opening of the sepals;
FIG. 3—illustrates a specimen of a floral bud wherein the sepals are more fully open;
FIG. 4—illustrates a specimen of a floral bud at the opening of the petals;
FIG. 5—illustrates a specimen of a flower in the course of further opening;
FIG. 6—illustrates a specimen of an open flower—plan view—obverse;
FIG. 7—illustrates a specimen of an open flower—plan view—reverse;
FIG. 8—illustrates a specimen of a fully open flower—plan view—obverse;
FIG. 9—illustrates a specimen of a fully open flower—plan view—reverse;
FIG. 10—illustrates a specimen of a floral receptacle showing the arrangement of the stamens and pistils;
FIG. 11—illustrates a specimen of a floral receptacle showing the arrangement of the pistils (stamens removed);
FIG. 12—illustrates a specimen of a flowering stem;
FIG. 13—illustrates a specimen of a main branch;
FIG. 14—illustrates a specimen of a leaf with three leaflets—plan view—upper surface;
FIG. 15—illustrates a specimen of a leaf with five leaflets—plan view—under surface; and
FIG. 16—illustrates a specimen of a leaf with seven leaflets—plan view—upper surface.
The chart used in the identification of the colors is that of The Royal Horticultural Society (R.H.S. Colour Chart). The description is based on the observation of 1½ -year-old plants during May while growing outdoors on their own roots at Le Cannet des Maures, Var, France.
The new ‘Meipeporia’ variety has not been observed under all possible environmental conditions to date. Accordingly, it is possible that the phenotypic expression may vary somewhat with changes in light intensity and duration, cultural practices, and other environmental conditions.
