Grandiflora rose plant named ‘Meikarady’

Abstract

A new and distinct variety of Grandiflora rose plant is provided that forms in abundance on a substantially continuous basis attractive double blossoms that are red-purple margined with red in coloration and display a pleasant fragrance. The vegetation is strong and a semi-erect growth habit is displayed. No particular susceptibility to disease has been noted during observations to date. The plant is particularly well suited for providing distinctive attractive ornamentation in the landscape.

Description

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

Varietal denomination: cv. Meikarady.

SUMMARY OF THE INVENTION

The new variety of Rosa hybrida Grandiflora 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 product of the cross of the ‘Meigriso’ variety (non-patented in the United States) and the ‘Jacpico’ variety (U.S. Plant Pat. No. 3,997). The male parent (i.e., the pollen parent) was the ‘Twobe’ variety (U.S. Plant Pat. No. 7,901). The parentage of the new variety can be summarized as follows:
(‘Meigriso’בJacpico’)בTwobe’.

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 Grandiflora rose plant of the present invention:

• • (a) forms strong vegetation,
  • (b) displays a semi-erect growth habit,
  • (c) abundantly and substantially continuously forms attractive large double blossoms that are red-purple margined with red in coloration and display a pleasant fragrance,
  • (d) displays attractive semi-glossy dark 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 upon an examination of the blossoms. For instance, ‘Meigriso’ variety is a Hybrid Tea that forms ruby red blossoms with a white reverse. The ‘Jacpico’ variety is a Hybrid Tea which forms white blossoms with a pink blush. The ‘Twobe’ variety is a Hybrid Tea which forms soft creamy pink blossoms with darker pink edges.

The new variety has been found to undergo asexual propagation at the south of France by a number of routes, including budding, grafting, and the use of cuttings. Such asexual propagation by the above-mentioned techniques in 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 ‘Meikarady’.

BRIEF DESCRIPTION OF THE PHOTOGRAPH

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 one year of age and were observed during October while budded on Rosa froebelli understock and growing outdoors at Le Cannet des Maures, Var, France. Dimensions in centimeters are indicated at the bottom of the photograph together with comparative color information.

DETAILED DESCRIPTION

The chart used in the identification of the colors is that of The Royal Horticultural Society (R.H.S. Colour Chart), London, England. Common color terms are to be accorded their customary dictionary significance. The description is based on the observation of one-year-old plants during October while growing outdoors on Rosa froebeffi understock at Le Cannet des Maures, Var, France.
