Floribunda rose plant named ‘Meimacota’

Abstract

A new and distinct variety of Floribunda rose plant herein referred to by its cultivar name, ‘Meimacota’, is provided which forms an abundance of attractive, cup-shaped, red colored blossoms on a nearly continuous basis. The vegetation is vigorous and the growth habit is bushy. Attractive, dense, semi-glossy, green foliage is formed. Very good resistance to pests and disease is exhibited, particularly against black spot. Additionally, the new variety is particularly well suited for growing as distinctive ornamentation in the landscape.

Description

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

Varietal denomination: cv. Meimacota.

SUMMARY OF THE INVENTION

The new variety of Rosa hybrida Floribunda rose plant of the present invention was created during June of 2004 at le Cannet des 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) was the ‘Noawel’ variety (non-patented in the United States). The male parent (i.e., the pollen parent) of the new variety was the ‘Radrazz’ variety (U.S. Plant Pat. No. 11,836). The parentage of the new variety can be summarized as follows:
‘Noawel’ x ‘Radrazz’.

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 possesses the following combination of characteristics:

• • (a) abundantly and substantially continuously forms attractive, cup-shaped, red colored blossoms,
  • (b) exhibits a bushy growth habit,
  • (c) forms very dense, semi-glossy, green foliage,
  • (d) exhibits very good resistance to pests and disease, particularly with respect to black spot, and
  • (e) is well suited for providing attractive ornamentation.

A new rose variety is provided displaying attractive, cup-shaped red blossoms combined with substantially continuous blossoming and very good disease resistance.

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

The new variety can be readily distinguished from its ancestors. More specifically, the new variety can be readily distinguished from the seed parental variety, ‘Noawel’ (non-patented in the United States), in that the new variety exhibits a bushy growth habit, while the seed parent ‘Noawel’ exhibits a ground cover growth habit. The new variety can be readily distinguished from the pollen parent, ‘Radrazz’ (U.S. Plant Pat. No. 11,836), in that the new variety displays 48-62 petals on average, while the pollen parent ‘Radrazz’ displays far fewer petals, only 10 petals on average. Moreover, the new variety can be readily distinguished from related known non-parental varieties. For example, the ‘Meipeporia’ variety (U.S. Plant Pat. No. 26,298) displays approximately 25 petals, whereas the new variety displays approximately 48-62 petals.

The plant of the new variety was asexually reproduced by rooting of cuttings in le Cannet des Maures, Var, France. The characteristics of the new variety have been found to be homogeneous and stable and to be strictly transmissible by asexual propagation, such as budding, grafting, and the rooting of cuttings from one generation to another. The new variety reproduces in a true-to-type manner by such asexual propagation.

The new variety has been named ‘Meimacota’.

BRIEF DESCRIPTION OF THE PHOTOGRAPHS

The accompanying photographs show, 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.
