Hybrid tea rose plant named ‘Meimonkeur’

Abstract

A new and distinct Hybrid Tea rose plant is provided that forms abundantly and substantially continuously attractive red-purple very double blossoms with substantially lighter non-uniform red-purple coloration on the under surface and an anise fragrance. The growth habit is bushy, and strong vegetation is formed. The vegetation is dense and bears a glossy aspect on the upper surface. No particular disease problem has been observed. The plant is particularly well suited for providing attractive ornamentation in parks and gardens.

Description

Botanical/commercial classification: Rosa hybrida/Hybrid Tea Rose Plant.

Varietal denomination: cv. Meimonkeur.

SUMMARY OF THE INVENTION

The new variety of Rosa hybrida Hybrid Tea 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 ‘Meipierar’ variety (U.S. Plant Pat. No. 7,622) and ‘Meivildo’ variety (U.S. Plant Pat. No. 6,895). The male parent (i.e., the pollen parent) was the product of the cross of the ‘Meicapula’ variety (non-patented in the United States) and the ‘Meinuzeten’ variety (U.S. Plant Pat. No. 4,224).

The parentage of the new variety can be summarized as follows:
(‘Meipierar’בMeivildo’)×(‘Meicapula’בMeinuzeten’).

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 Hybrid Tea 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 red-purple very double blossoms with substantially lighter non-uniform red-purple coloration on the under surface which display an anise fragrance,
  • (c) exhibits attractive dense glossy medium green foliage, and
  • (d) is particularly well suited for providing attractive ornamentation in parks and gardens.

The new variety well meets the needs of the horticultural industry and can be grown to advantage in the landscape where attractive ornamentation is to be provided.

The new variety can be readily distinguished from its ancestors. For instance, the bicolored red-purple blossom coloration of the new variety is considerably different from that of its ancestors. More specifically, the ‘Meipierar’ variety forms cream white blossoms, the ‘Meivildo’ variety forms neyron pink blossoms, the ‘Meicapula’ variety forms pink blossoms, and the ‘Meinuzeten’ variety forms orange-red blossoms.

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 ‘Meimonkeur’.

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 1-½ years of age and were observed during June while budded on Rosa laxa understock and growing outdoors at Le Cannet des Maures, Var, France. Standard colors are presented at the bottom of the photograph for comparative purposes.

DETAILED DESCRIPTION

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 1-½-year-old plants during June which were budded on Rosa laxa understock and growing outdoors at Le Cannet des Maures, Var, France.
