USPP22897P3 - Hybrid Tea rose plant named ‘Meigrilega’ - Google Patents

Abstract

A new and distinct Hybrid Tea rose plant is provided that abundantly and substantially continuously forms attractive fully double magenta blossoms that are lavender-pink on the reverse. The blossom configuration is somewhat formal and displays well when cut and placed in a vase. The plant exhibits vigorous vegetation and an upright and bushy growth habit. The foliage is ornamental dark green with a glossy finish. A sweet fragrance is provided by the blossoms. The plant is well suited for growing as attractive ornamentation in parks and gardens.

Description

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

Varietal denomination: cv. Meigrilega.

SUMMARY OF THE INVENTION

The new variety of Rosa hybrida Hybrid Tea rose plant of the present invention was created in France by artificial pollination during June 1998 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 ‘Meigriso’ variety (non-patented in the United States). The male parent (i.e., the pollen parent) of the new variety was the ‘Twobe’ variety (U.S. Plant Pat. No. 7,901). The parentage of the new variety can be summarized as follows:
‘Meigriso’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 Hybrid Tea rose plant of the present invention possesses the following combination of characteristics:

• • (a) abundantly and substantially continuously forms attractive fully double magenta blossoms that are lavender-pink on the reverse,
  • (b) exhibits an upright and bushy growth habit,
  • (c) forms vigorous vegetation,
  • (d) forms attractive ornamental dark green foliage with a glossy finish, and
  • (e) is well suited for providing attractive ornamentation in the landscape.

The new variety well meets the needs of the horticultural industry. It can be grown to advantage as ornamentation in parks, gardens, public areas, and in residential settings. The new variety is particularly well suited for providing attractive ornamentation in the landscape. During observations to date the disease resistance has been above average for the type. The brightly colored magenta blossoms contrast nicely with the ornamental dark green foliage. Additionally, the blossom configuration is somewhat formal and displays well when cut and placed in a vase.

The new variety of the present invention can be readily distinguished from its ancestors through an inspection of the blossom coloration. More specifically, the ‘Meigriso’ variety forms ruby-red blossoms that are whitish on the reverse, and the ‘Twobe’ variety forms blossoms that are Neyron Rose to Rhodonite Red in coloration.

The new variety of the present invention also can be readily distinguished from other fragrant Hybrid Tea rose varieties such as the ‘Wezeip’ variety (U.S. Plant Pat. No. 4,552) and the ‘Tanallepal’ variety (non-patented in the United States). More specifically, the blossoms of the ‘Wezeip’ variety display a lesser number of petals and are of a dissimilar silvery lavender coloration shading to ruby-red at the edges. The blossoms of the ‘Tanallepal’ variety also display a lesser number of petals and are of a dissimilar color combination wherein the upper surface is cherry red and the under surface is white-to-silver.

The characteristics of the new variety have been found at Le Cannet-des-Maures, Var, France, and at Waso, Calif., U.S.A., to be homogeneous and stable and to be strictly transmissible by asexual propagation, such as budding, grafting, and the rooting of cuttings from one generation to another. Accordingly, the new variety reproduces in a true-to-type manner by such asexual propagation.

The new variety has been named ‘Meigrilega’ and will be marketed in the United States under the GIRLS' NIGHT OUT trademark.

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, a representative blossom and foliage of the new variety.

The plant was approximately two years of age and was observed during June while growing outdoors in a container at West Grove, Pa., U.S.A.
