Abstract

A new and distinct variety of bedding rose plant, referred to by its cultivar name, ‘MEIZILENA’, is disclosed. The new variety forms on a nearly continuous basis attractive, cup shaped, red colored flowers. The red coloration of the flower intensifies gradually with the opening of the flower. Attractive, dense and glossy foliage is formed, which contrasts beautifully with the blossoms. An erected growth habit is displayed. The new variety is well suited for providing attractive ornamentation in the landscape.

Description

Botanical/commercial classification:

Latin name—Rosa hybrida.

Varietal denomination—‘MEIZILENA’.

CROSS-REFERENCE TO RELATED APPLICATIONS

This application claims priority to Plant Breeders' Right Application Number 2020/2338, which was filed at Community Plant Variety Office in the European Union on Sep. 24, 2020, the contents of which are hereby incorporated by reference for all purposes.

SUMMARY OF THE INVENTION

The new variety of Rosa hybrida plant was created by artificial pollination in Le Cannet des Maures, Var, France, 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 ‘ADHARMAN’ variety (non-patented). The male parent (i.e., the pollen parent) was the ‘BAICENT’ variety (U.S. Plant Pat. No. 18,102).

The parentage of the new variety can be summarized as follows:
‘ADHARMAN’ x ‘BAICENT’

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 variety of rose plant of the present invention possesses the following combination of characteristics:

- (a) forms a red colored flower, wherein the red coloration of the flower intensifies gradually with the opening of the flower, and
- (b) exhibits a dense and glossy foliage.

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. Accordingly, the plant is particularly well suited for growing in the landscape.

The new variety of the present invention can readily be distinguished from its ancestors. More specifically, the ‘ADHARMAN’ variety (i.e., the seed parent) displays smaller flowers compared to the new variety. The ‘BAICENT’ variety (i.e., the pollen parent) displays yellow colored flowers, whereas the new variety displays red colored flowers. Moreover, the new variety can be readily distinguished from other similar non-parental varieties. For example, the ‘MEIANYCID’ variety (U.S. Plant Pat. No. 27,894) displays yellow colored flowers, whereas the new variety displays red colored flowers.

The new variety has been found to undergo asexual propagation in Le Cannet des Maures, Var, France by a number of routes, including softwood cuttings and grafting t-bud. Asexual propagation by the above-mentioned techniques in 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 ‘MEIZILENA’.

The first offer for sale of the new variety was Oct. 23, 2020 in the United States of America by the inventor or another who obtained the new variety directly or indirectly from the inventor.

DETAILED BOTANICAL DESCRIPTION

The chart used in the identification of the colors is that of The Royal Horticultural Society (R.H.S. Colour Chart, 2001 edition), London, England.
