Floribunda rose plant named ‘KORnekcraz’

Abstract

A new and distinct variety of Floribunda rose plant, referred to by its cultivar name, ‘KORnekcraz’, is described. The new variety forms in abundance on a substantially continuous basis attractive, red and white striped colored blossoms. The vegetation is vigorous, and the growth habit is very bushy. Attractive dark green, glossy foliage is formed. Additionally, the new variety is particularly well suited for growing as distinctive ornamentation in the landscape.

Description

Latin name of genus and species of plant claimed: Rosa hybrida.

Variety denomination: ‘KORnekcraz’.

CROSS REFERENCE TO RELATED APPLICATIONS

This application claims priority to Plant Breeders' Right Application Number 2022/2229, which was filed at Community Plant Variety Office in the European Union on Oct. 6, 2022, the contents of which are hereby incorporated by reference for all purposes.

STATEMENT REGARDING PRIOR DISCLOSURES BY THE INVENTOR

The first offer for sale of the new variety was June 2022, in Germany. The first offer for sale of the new variety was by the inventor or another who obtained the new variety directly or indirectly from the inventor. No plants of the new variety have been sold in this country or anywhere in the world, nor has any disclosure of the new plant been made, more than one year prior the effective filing date of this application, and such sale or disclosure within one year was either derived directly or indirectly from the inventor.

BACKGROUND OF THE INVENTION

The new variety of floribunda rose plant of the present invention was created by controlled breeding in May 2012 at Offenseth-Sparrishoop, Germany 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) of the new variety was an unnamed breeder seedling (not patented). The male parent (i.e., the pollen parent) of the new variety was the ‘KORblohawa’ variety (not patented).

The parentage of the new variety can be summarized as follows:
Unnamed Breeder Seedling x ‘KORblohawa’

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.

The new variety has been found to undergo asexual propagation at Wasco, California and Cochranville, Pennsylvania by a number of routes such as vegetative cuttings. Asexual propagation techniques in Wasco, California and Cochranville, Pennsylvania, such as vegetative cuttings, have shown that the characteristics of the new variety are homogeneous, stable, and strictly transmissible by such asexual propagation from one generation to another. Accordingly, the new variety undergoes asexual propagation in a true-to-type manner.

SUMMARY OF THE INVENTION

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

• • (a) forms attractive, red and white striped blossoms,
  • (b) exhibits a very bushy growth habit,
  • (c) forms vigorous vegetation, and
  • (d) provides attractive ornamental glossy, dark green colored foliage.

The new variety well meets the needs of the horticultural industry. It can be grown to advantage as attractive ornamentation in parks, gardens, public areas, and residential landscapes. Accordingly, it is particularly well suited for growing in the landscape.

The new variety can be readily distinguished from its ancestors. More specifically, the unnamed breeding seedling female parent (i.e., the seed parent) displays a less bushy growth habit and exhibits flowers with more petals compared to the new variety. Also, the seed parent forms flowers which have pink and white colored striping, whereas the new variety forms flowers which have red and white colored striping. Additionally, the new variety provides flatter to open flower shape compared to the ‘KORblohawa’ variety (i.e., the pollen parent) and the flower type of the new variety is single, whereas the flower type of the ‘KORblohawa’ variety is double. Moreover, the new variety can be readily distinguished from non-parental related similar varieties. For example, ‘Wekplapep’ (U.S. Plant Pat. No. 10,126) displays more petals and exhibits more fragrance compared to the new variety.

The new variety has been named the ‘KORnekcraz’ variety.

BRIEF DESCRIPTION OF THE PHOTOGRAPHS

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 new variety and blossoms of the new variety. The illustrated rose plants of the new variety were approximately two years of age and were grown outdoors in a field in Ellerhoop, Germany in June 2022.

DETAILED BOTANICAL DESCRIPTION

The chart used in the identification of colors is that of The Royal Horticultural Society (The R.H.S. Colour Chart, 2015 edition). 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 a two-year-old specimen of the new variety, observed during June, while growing on its own roots in a three-gallon container in a nursery in Cochranville, Pennsylvania.
