Abstract

A new and distinct Hybrid Tea rose plant is provided that forms at mid-season abundantly and substantially continuously attractive bright red-purple blossoms. The medium-sized buds are globular-shaped. The growth habit is semi-erect, and the stems are extremely rigid. The vegetation is very strong and attractive very dense leathery glossy dark green foliage is formed. The plant is particularly well suited for providing attractive ornamentation in the landscape.

Description

Botanical/commercial classification: Rosa hybrida/Hybrid Tea Rose Plant.
Varietal denomination: cv. Meikolyma.
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 ‘Macnon’ variety (non-patented in the United States). The male parent (i.e., the pollen parent) was the product of the cross of the ‘Meironsse’ variety (U.S. Plant Pat. No. 8,496) and the ‘Meipsilon’ variety (non-patented in the United States).
The parentage of the new variety can be summarized as follows:
‘Macnon’×(‘Meironsse’בMeipsilon’).
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 semi-erect growth habit with strong vegetation and extremely rigid stems,
    • (b) forms medium-sized globular-shaped buds,
    • (c) forms at mid-season abundantly and substantially continuously attractive bright red-purple blossoms,
    • (d) displays attractive very dense leathery glossy dark green foliage, and
    • (e) is particularly well suited for providing attractive ornamentation in the landscape.
The blossoms tend to emit a very slight fragrance that is reminiscent of tea and cut grass.
The new variety well meets the needs of the horticultural industry and can be grown to advantage in the landscape.
The new variety can be readily distinguished from its ancestors. For instance, the blossom appearance is considerably different from that of the ‘Macnon’, ‘Meironsse’, and ‘Meipsilon’ varieties. More specifically, the ‘Macnon’ variety forms medium pink blossoms having a lesser number of petals, the ‘Meironsse’ variety forms blossoms which display an orange blend/copper coloration, and the ‘Meipsilon’ variety forms bicolored red and yellow blossoms.
The new variety also can be readily distinguished from the ‘Meizeli’ variety (U.S. Plant Pat. No. 8,391) and the ‘Meizincaro’ variety (U.S. Plant Pat. No. 11,660). The ‘Meizeli’ variety forms dissimilar pink blossoms having a substantially lesser number of petals. The ‘Meizincaro’ variety forms dissimilar Cardinal Red blossoms having a somewhat lesser number of 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 ‘Meikolyma’.
