Floribunda rose plant named ‘Meitalrea’

Abstract

A new and distinct variety of Floribunda rose plant is provided that abundantly and substantially continuously forms attractive single cup-shaped blossoms displaying at opening an irregular blend of yellow and luminous red which evolves to a greater concentration of red at maturity. The vegetation is strong. A bushy growth habit is displayed. The foliage is dense dark green with a glossy upper surface. The tolerance to disease is good, with a light sensitivity to black spot having been observed during observations to date. The plant is well suited for providing distinctive attractive ornamentation in the landscape.

Description

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

Varietal denomination: cv. Meitalrea.

SUMMARY OF THE INVENTION

The new variety of Rosa hybrida Floribunda rose plant was created in 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 an unnamed and unreleased seedling (non-patented). The male parent (i.e., pollen parent) additionally was an unnamed and unreleased seedling (non-patented).

The parentage of the new variety can be summarized as follows:
Unnamed Seedling×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 Floribunda rose plant of the present invention:

• • (a) forms strong vegetation,
  • (b) exhibits a bushy growth habit with dense dark green foliage having a glossy upper surface,
  • (c) abundantly and substantially continuously forms attractive single cup-shaped blossoms displaying at opening an irregular blend of yellow and luminous red which evolves to a greater concentration of red with maturity, and
  • (d) is well suited for providing distinctive attractive ornamentation in the landscape.

The tolerance to disease is good with a light sensitivity to black spot (i.e., Diplocarpon rosae), sometimes known as Marsonia, having been observed during observations to date.

The new variety of the present invention can be readily distinguished from its ancestors. More specifically, the female parent displays a dusted ochre blossom coloration, and the male parent displays an ochre streaked with yellow blossom coloration.

The new variety also can be readily distinguished from the ‘Meisiastri’ variety (U.S. Plant Pat. No. 20,719) and the ‘Radfifth’ variety (U.S. Plant Pat. No. 22,316). More specifically, the ‘Meisiastri’ variety forms dissimilar blossoms that are coral in coloration with substantial cream-to-yellow striping, and the ‘Radfifth’ variety displays a dissimilar upright and climbing growth habit.

The new variety well meets the needs of the horticultural industry and can be grown to advantage as colorful ornamentation in parks and gardens.

The new variety has been found to undergo asexual propagation at Le Cannet des Maures, Var, France, by a number of routes, including budding, grafting, and the use of cuttings. Such asexual propagation by the above-mentioned techniques 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 ‘Meitalrea’.

DETAILED BOTANICAL DESCRIPTION

The chart used in the identification of the colors is that of The Royal Horticultural Society (R.H.S. Colour Chart—1995) except where ordinary color terms are utilized. Common color terms are to be accorded their customary dictionary significance. The description is based upon the observation of plants of the new variety at an age of approximately two years during the month of May while being grown outdoors while budded on Rosa laxa rootstock at Le Cannet des Maures, Var, France.
