Grandiflora Rose plant named ‘Meiroylear’
A new and distinct variety of Grandiflora rose plant is provided that forms on a recurrent basis attractive double blossoms that are bright red with yellow stripes finishing to medium pink and cream. The vegetation is vigorous and a bushy upright growth habit is displayed. Susceptibility to Black Spot has been observed during observations to date. The plant is particularly well suited for providing distinctive attractive ornamentation in the landscape.

Botanical/commercial classification: Rosa hybrida/Grandiflora Rose Plant.
Varietal denomination: cv. Meiroylear.
SUMMARY OF THE INVENTIONThe new variety of Rosa hybrida Grandiflora rose plant was created in France during May 1997 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 ‘Meipsilon’ variety (non-patented in the United States) and the ‘Meivestal’ variety (non-patented in the United States). The male parent (i.e., the pollen parent) was the ‘Wekplapep’ variety (U.S. Plant Pat. No. 10,126). This ‘Meipsilon’ variety is marketed under the YAKIMOUR trademark. The ‘Meivestal’ variety is marketed under the SENATOR BURDA trademark. The ‘Wekplapep’ variety is marketed under the SENTMENTAL trademark. The parentage of the new variety can be summarized as follows:
(‘Meipsilon’בMeivestal’)בWekplapep’.
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 during June 2001 resulted in the identification of a single plant of the new variety.
It was found that the new Grandiflora rose plant of the present invention:
-
- (a) forms vigorous vegetation,
- (b) forms a bushy upright growth habit,
- (c) abundantly and substantially continuously forms attractive double blossoms that are bright red with yellow stripes finishing to medium pink and cream,
- (d) displays attractive glossy medium green foliage, and
- (e) is particularly 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.
The new variety can be readily distinguished from its ancestors. For instance, ‘Meipsilon’ variety is a Hybrid Tea that forms blossoms which display a red blend coloration. The ‘Meivestal’ variety is a Hybrid Tea which forms brilliant currant red blossoms having an intense fragrance. The ‘Wekplapep’ variety is a Floribunda which forms intensely fragrant blossoms having a red blend coloration.
Additionally, the new variety can be readily distinguished from the ‘Meisiastri’ variety (U.S. Plant patent application Ser. No. 12/314,185 filed concurrently herewith). Unlike the new variety of the present invention, the ‘Meisiastri’ variety is a Floribunda that forms striped red and pink blossoms.
The new variety has been found to undergo asexual propagation at Wasco, Calif., U.S.A., by a number of routes, including budding, grafting, and the use of cuttings. 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 ‘Meiroylear’, and is being marketed under the ALL AMERICAN MAGIC trademark.
The accompanying photograph shows as nearly true as it is reasonably possible to make the same, in a color illustration of this character, a typical specimen of the new variety. Blossoms in various stages of development as well as foliage are illustrated. The illustrated plant was approximately two years of age, and was being grown outdoors at Wasco, Calif., U.S.A.
The chart used in the identification of the colors is that of The Royal Horticultural Society (R.H.S. Colour Chart) 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 of plants of the new variety at an age of approximately five years during the month of August while being grown near West Grove, Pa., U.S.A.
