The vegetation is vigorous and the plant possesses a climbing growth habit. The plant exhibits good disease resistance particularly with respect to Marssonina disease.

Description

SUMMARY OF THE INVENTION

The new variety of Shrub rose plant of the present invention was created by artificial pollination wherein two parents were crossed which previously has 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 pollination of the `Centenaire de Lourdes` variety (non-patented in the United States) and the `Picasso` variety (U.S. Plant Pat. No. 3,351). The male parent (i.e., the pollen parent) of the new variety was the `Meihaiti` variety (non-patented in the United States). The parentage of the new variety can be summarized as follows:

(`Centenaire de Lourdes`.times.`Picasso`).times.`Meihaiti`.

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 is found that the new variety of shrub rose plant possesses the following combination of characteristics:

(a) forms attractive bright red blossoms,

(b) exhibits a propensity for climbing,

(c) exhibits a good ability to reflower,

(d) exhibits a good resistance to Marssonina disease, and

(e) is particularly suited for growing as ornamentation in the landscape.

The new variety meets the needs of the horticultural industry. It can be grown to particular advantage as attractive ornamentation in parks, gardens, public areas, and residential landscapes.

The characteristics of the new variety have been found to be homogeneous and stable and are strictly transmissible by asexual propagation carried out in France (e.g., by budding, grafting, and cuttage) from one generation to another.

The newe variety has been named the `Meiriental` variety.

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 described herein were three years of age and were observed during June while budded on Rosa froebelii understock and growing outdoors at Le Cannet des Maures, Var, France.
