Bedding rose plant named ‘MEIWENTAR’

Abstract

A new and distinct variety of bedding rose plant, referred to by its cultivar name, ‘MEIWENTAR’, is described. The new variety exhibits a compact growth habit. The flowers form a striped coloration. Ornamental dense semi-glossy foliage is formed. Additionally, the new variety is particularly well suited for growing as distinctive ornamentation in the landscape.

Description

Latin name of genus and species of plant claimed: Rosa hybrida.

Variety denomination: ‘MEIWENTAR’.

STATEMENT REGARDING PRIOR DISCLOSURES BY THE INVENTOR

The first sale of the new variety was Feb. 1, 2024, in the United States of America from STAR® Roses and Plants. The first offer for sale and first sale of the new variety, and subsequent offer for sales and sales, was by the inventor or another who obtained the new variety directly or indirectly from the inventor. No plants of the new variety have been sold in this country or anywhere in the world, nor has any disclosure of the new plant been made, more than one year prior the effective filing date of this application, and such sale or disclosure within one year was either derived directly or indirectly from the inventor.

BACKGROUND OF THE INVENTION

The new variety of rose plant of the present invention was created by controlled breeding in Le Cannet de Maures, Var, France 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) of the new variety was the ‘MEIGELSI’ variety (not patented). The male parent (i.e., the pollen parent) of the new variety was an unnamed seeding (not patented) which was the product of the cross between the ‘KORFALT’ variety (not patented) and an unnamed seedling (not patented).

The parentage of the new variety can be summarized as follows:
‘MEIGELSI’ x (‘KORFALT’ x unnamed seedling)

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.

The new variety has been found to undergo asexual propagation in Le Cannet des Maures, Var, France by a number of routes, including eye budding, softwood cuttings, and hardwood cuttings. Asexual propagation by the above-mentioned techniques in Le Cannet des Maures, Var, France has shown that the characteristics of the new variety are homogeneous, stable, and strictly transmissible by such asexual propagation from one generation to another. Accordingly, the new variety undergoes asexual propagation in a true-to-type manner.

SUMMARY OF THE INVENTION

It was found that the new variety of bedding rose plant of the present invention possesses the following combination of characteristics:

• • (a) exhibits a compact growth habit,
  • (b) displays a striped flower coloration, and
  • (c) forms dense semi-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 residential landscapes. Accordingly, it is particularly well suited for growing in the landscape.

The new variety can be readily distinguished from its ancestors. More specifically, the ‘MEIGELSI’ variety (i.e., the seed parent) displays flowers that are not striped colored compared to the flowers of the new variety that display petals with striped coloration. Additionally, the new variety exhibits a double flower form, whereas the unnamed seedling male parent (‘KORFALT’ x unnamed seedling) (i.e., the pollen parent) exhibits a semi-double flower form. Moreover, the new variety can be readily distinguished from non-parental related similar varieties. For example, the ‘Sproulsun’ variety (U.S. Plant Pat. No. 31,645) displays striped blossoms with a darker pink color compared to the striped blossoms of the new variety.

The new variety has been named the ‘MEIWENTAR’ variety.
