Shrub rose plant named ‘Meiklutz’

Abstract

A new and distinct variety of Shrub Rose plant is provided that abundantly forms attractive small cup-shaped pink blossoms. A bushy and compact growth habit is displayed and the foliage is rather dense and semi-glossy. The disease tolerance is good particularly with respect to Marsonina rosea. The plant is well suited for providing attractive ornamentation in the landscape, such as in parks and gardens.

Description

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

Varietal denomination: cv. Meiklutz.

SUMMARY OF THE INVENTION

The new variety of Rosa hybrida shrub 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 ‘Noatraum’ variety (U.S. Plant Pat. No. 7,282) and an unnamed seedling (non-patented in the United States). The ‘Noatraum’ variety is marketed under the FLOWER CARPET Pink Trademark. The male parent (i.e., the pollen parent) was ‘The Fairy’ variety (non-patented in the United States).
(‘Noatraum’×Unnamed Seedling)בThe Fairy’.

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 Shrub rose plant of the present invention:

• • (a) exhibits a bushy and compact growth habit,
  • (b) forms in abundance attractive small cup-shaped pink blossoms,
  • (c) displays rather dense semi-glossy green foliage,
  • (d) exhibits excellent tolerance to diseases particularly with respect to Marsonina rosea, and
  • (e) is particularly well suited for growing as attractive ornamentation in the landscape.

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

The new variety can be readily distinguished from its ancestors. For instance, the blossom appearance is considerably different from that of the ‘Noatraum’ and ‘The Fairy’ varieties. More specifically, the ‘Noatraum’ blossoms are larger and are darker pink in coloration. The blossoms of ‘The Fairy’ variety are lighter pink in coloration.

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 techniques 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 ‘Meiklutz’.

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 June while growing on Rosa froebelli understock outdoors at Le Cannet des Maures, Var, France. Dimensions in centimeters and a standard color presentation are indicated at the bottom of the photograph.

DETAILED DESCRIPTION

The chart used in the identification of the colors is that of The Royal Horticultural Society (R.H.S. Colour Chart). The description is based on the observation of one-year-old plants during May while budded on Rosa froebelli understock and growing in greenhouses at Le Cannet des Maures, Var, France.
