Abstract

A new and distinct variety of Floribunda rose plant is provided which abundantly forms on a nearly continuous basis attractive Cardinal red blossoms having five petals and a yellow eye. The plant exhibits strong vegetation, a low and compact growth habit, very dense medium green foliage with a glossy aspect, and good tolerance to Oidium. The attractive medium green glossy foliage contrasts nicely with the red blossom coloration. The new variety is particularly well suited for growing as attractive ornamentation in parks and gardens.

Description

Botanical/commercial classification: Rosa hybrida/Floribunda Rose Plant.

Varietal denomination: cv. Meifrichty.

SUMMARY OF THE INVENTION

The new variety of Rosa hybrida Floribunda rose 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 product of the cross of the ‘Meineble’ variety (U.S. Plant Pat. No. 7,116) and the ‘Meipoque’ variety (U.S. Plant Pat. No. 5,956). The male parent (i.e., the pollen parent) was the ‘Korimro’ variety (non-patented in the United States). The parentage of the new variety can be summarized as follows: (‘Meineble’×‘Meipoque’)×‘Korimro’.

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 Floribunda rose plant of the present invention:

- (a) exhibits a low and compact growth habit,
- (b) abundantly forms on a nearly continuous basis attractive Cardinal red blossoms having five petals and a yellow eye,
- (c) forms very dense medium green foliage having a glossy aspect that contrasts well with the blossom coloration, and
- (d) is particularly well suited for growing as attractive ornamentation in parks and gardens.

The disease tolerance is very good with respect to Oidium, and the blossom coloration is relatively stable.

The new variety well meets the needs of the horticultural industry and can be grown to advantage in the landscape where attractive ornamentation is desired.

The new variety can be readily distinguished from its ancestors. For instance, the ‘Meineble’ variety displays a considerably taller growth habit. The ‘Meipoque’ and ‘Korimro’ varieties each form blossoms having a dissimilar pink coloration.

Additionally, the new variety can be readily distinguished from the ‘Eye Paint’ (U.S. Plant Pat. No. 3,985) and ‘Meirumour’ (U.S. Plant Pat. No. 9,251) varieties. Each of these comparative varieties displays a significantly taller growth habit.

The new variety has been found to undergo asexual propagation in France by a number of routes, including budding, grafting, and the use of cuttings. Asexual propagation by the above-mentioned techiques in 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.

The new variety has been named ‘Meifrichty’.

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 were approximately one year of age and were observed during September while budded on Rosa froebelli understock and growing outdoors at Le Cannet des Maures, Var, France. Dimensions in centimeters are indicated at the bottom of the photograph.
