Abstract

A new and distinct variety of Floribunda Rose Plant, herein referred to by its cultivar name, ‘KORfloci111’, is provided which forms attractive, cup-like white colored blossoms. The vegetation is vigorous and the growth habit is very bushy and rounded. Attractive semi-glossy, medium-green ornamental foliage is formed. Very good disease resistance is exhibited. The new variety is particularly well suited for providing distinctive ornamentation in the landscape.

Description

Botanical/commercial classification:

Latin name—Rosa hybrida.

Common name—Floribunda Rose Plant.

Varietal denomination: ‘KORfloci111’.

SUMMARY OF THE INVENTION

The new variety of Rosa hybrida Floribunda Rose Plant of the present invention was created by controlled breeding during May 2005 at 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., seed parent) of the new variety was an unnamed seedling (non-patented) resulting from a cross of the ‘KORpeligo’ variety (non-patented) and an unnamed seedling. The male parent (i.e., pollen parent) of the new variety was the ‘KORfloci12’ variety (non-patented).

The parentage can be summarized as follows:
(‘KORpeligo’ x unnamed seedling) x ‘KORfloci12’

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) forms attractive cup-like white colored blossoms,
- (b) exhibits a very bushy and rounded growth habit,
- (c) forms vigorous vegetation,
- (d) forms attractive ornamental semi-glossy, medium green foliage, and
- (e) exhibits 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 settings. 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 unnamed seedling from the (‘KORpeligo’ x unnamed seedling) cross (i.e., seed parent) exhibits a light pink colored flower, which is smaller in size and has less petals per flower compared to the white colored flower of the new variety. Additionally, the ‘KORfloci12’ variety (i.e., pollen parent) exhibits a crimson red with a cream reverse colored flower, which has more petals per flower compared to the white colored flower of the new variety and the ‘KORfloci12’ variety provides a lower level of disease resistance compared to the new variety. Moreover, the new variety can be readily distinguished from non-parental related similar varieties. For example, the ‘Meidelweis’ variety (U.S. Plant Pat. No. 17,841) displays flowers with more petals, exhibits more fragrance, and produces a darker green foliage compared to the new variety.

The new variety has been found to undergo asexual propagation at Wasco, Calif. and Cochranville, Pa. by a number of routes such as vegetative cuttings. Asexual propagation techniques in Wasco, Calif. and Cochranville, Pa., 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.

The new variety has been named ‘KORfloci111’.

BRIEF DESCRIPTION OF THE PHOTOGRAPHS

The accompanying photograph shows, as nearly true as it is reasonably possible to make the same in color illustrations of this character, a typical specimen of the new variety. The illustrated rose plant of the new variety was approximately two years of age and was observed at Cochranville, Pa. while growing outdoors on its own roots in a three-gallon container.

FIG. 1—illustrates a specimen of the plant displaying floral buds and flowers at varying points of opening.

DETAILED BOTANICAL DESCRIPTION

The chart used in the identification of colors is that of The Royal Horticultural Society (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 the observation of a two-years-old specimen of the new variety, observed during May, while growing in a three-gallon container on its own roots at Cochranville, Pa.
