Ground cover rose plant named ‘MEIFRANJIN’

Abstract

A new and distinct variety of ground cover rose plant, referred to by its cultivar name, ‘MEIFRANJIN’, is disclosed. The new variety forms on a nearly continuous basis attractive, cup shaped, pink double colored flowers. Attractive, dense and glossy foliage is formed, which contrasts beautifully with the blossoms. A ground cover 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: ‘MEIFRANJIN’.

SUMMARY OF THE INVENTION

The new variety of Rosa hybrida 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 ‘THE FAIRY’ variety (non-patented). The male parent (i.e., the pollen parent) was an unnamed seedling (non-patented), which is the progeny of the cross between the ‘KORMAX’ variety (non-patented) and an unnamed seedling variety (non-patented).

The parentage of the new variety can be summarized as follows:
‘THE FAIRY’ x (‘KORMAX’ 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.

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

• • (a) forms a compact and well-balanced plant,
  • (b) provides pink colored double flower, and
  • (c) 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 ‘THE FAIRY’ variety (i.e., the seed parent) displays a more bushy growth habit compared to the new variety. The ‘KORMAX’ variety (i.e., the paternal grandmother) displays red colored flowers, whereas the new variety displays pink colored flowers. The unnamed seedling pollen parent from the cross (‘KORMAX’ x unnamed seedling) displays red with yellow eye colored flowers, whereas the new variety displays pink colored flowers. Moreover, the new variety can be readily distinguished from other similar non-parental varieties. For example, the ‘MEIGALPIO’ variety (U.S. Plant Pat. No. 17,877) displays red pink colored flowers, whereas the new variety displays pink 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 ‘MEIFRANJIN’.

The new variety has not been offered for sale nor was the new variety publicly available at this time of filing the instant application.

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. The terminology which precedes reference to the chart has been added to indicate the corresponding color in more common terms. The description is based on the observation of five-years-old specimens of the new variety during July while budded on their own roots and growing outdoors at Le Cannet des Maures, Var, France.
