Abstract

A new and distinct variety of floribunda rose plant, referred to by its cultivar name, ‘KORfloci114’, is described. The new variety forms in abundance on a substantially continuous basis yellow-colored blossoms. The vegetation is vigorous, and the growth habit is compact and rounded. Additionally, the new variety is particularly well suited for growing as distinctive ornamentation in the landscape.

Description

CROSS REFERENCE TO RELATED APPLICATIONS

This application claims priority to U.S. Provisional Patent Application No. 63/654,235, which was filed on May 31, 2024, the contents of which are hereby incorporated by reference for all purposes.

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

Variety denomination: ‘KORfloci114’.

STATEMENT REGARDING PRIOR DISCLOSURES BY THE INVENTOR

The first offer for sale of the new variety was June 2023, on the KORDES website. The first sale or 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 to 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 2010 in Sparrieshoop, 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) was an unnamed breeder seedling (not patented). The male parent (i.e., the pollen parent) of the new variety was ‘WEKvossutono’ (U.S. Plant Pat. No. 18,473).

The parentage of the new variety can be summarized as follows:
unnamed breeder seedling x ‘WEKvossutono’

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) abundantly and substantially continuously forming yellow-colored blossoms,
- (b) exhibiting a compact and rounded growth habit, and
- (c) forming vigorous vegetation.

The new variety well meets the needs of the horticultural industry. It can be grown to advantage as distinctive 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 new variety displays a larger flower size, more golden yellow flower color, and a higher petal count compared to the unnamed breeder seedling parent (i.e., the seed parent). Additionally, the new variety displays a more golden yellow flower color, a more compact growth habit, exhibits less petaloids, and better disease resistance compared to the ‘WEKvossutono’ variety (i.e., the pollen parent). Moreover, the new variety can be readily distinguished from non-parental related similar varieties. For example, the new variety displays a slightly smaller flower diameter, and a different shade of yellow flower color compared to the ‘KORfloci52’ (U.S. Plant Pat. No. 23,314).

The new variety has been named the ‘KORfloci114’ 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, a typical specimen of the new variety and blossoms of the new variety. The illustrated rose plant of the new variety was approximately two years of age and was grown outdoors in a field on understock in Wasco, California, U.S.A. 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 and The R.H.S. Colour Chart designation used herein represents the closest color observed on the majority of the specified botanical feature. The description is based on a two-year-old specimen of the new variety, observed during May 2024, while growing on its own roots in a three-gallon container in Cochranville, Pennsylvania.
