CROSS REFERENCES AND FEDERAL R&D STATEMENT

There are no cross referenced or related applications. This variety was developed without the aid of any research grant.

BACKGROUND OF THE INVENTION

The present discovery constitutes a new and distinct variety of a floribunda rose which was discovered in a cultivated area in May, 2002. The new rose variety resulted from a naturally occurring mutation of unknown causation on a branch of ‘KORtonetec’, a non-patented rose plant.

The new rose plant was asexually propagated for further evaluation. This new and distinctive FLORIBUNDA rose variety is named ‘KORfree-0006’.

SUMMARY OF THE INVENTION

The new rose plant may be distinguished from ‘KORtonetec’ by the following combination of characteristics:

    • 1. ‘KORtonetec’ has bicolor, red and yellow flowers, while ‘KORfree-0006’ has peach colored flowers.

The objective of the hybridization was to create a new and distinct rose plant with unique qualities, such as:

    • 1. Uniform growth and flowering;
    • 2. Abundant, attractive, recurrent peach-colored flowers;
    • 3. Attractive and abundant foliage; and
    • 4. Resistance to diseases encountered in landscapes and gardens.

This combination of qualities is not present in prior rose cultivars known to the inventor. These objectives have been substantially achieved and in that distinguish ‘KORfree-0006’ from all other varieties of which we are aware.

As part of a rose development program, Tim-Hermann Kordes asexually propagated the mutation by grafting and conducted evaluations and observations on the resulting plants in a controlled environment in Offenseth-Sparrieshoop, Germany. The resulting plants exhibited distinctive physical and biological characteristics. The first asexual reproduction of ‘KORfree-0006’ was done by grafting in July, 2003 at the inventor's nursery in Offenseth-Sparrieshoop, Germany.

This initial and other subsequent propagations conducted in controlled environments demonstrate that ‘KORfree-0006’ reproduces true to type in successive generations of asexual reproduction.

BRIEF DESCRIPTION OF THE DRAWING

The accompanying color drawing shows as true as is reasonably possible to obtain in color photographs of this type, the typical characteristics of the buds, flowers, leaves, and stems of ‘KORfree-0006’.

 DETAILED BOTANICAL DESCRIPTION

The following is a description of ‘KORfree-0006’, as observed growing in October, 2009, in a nursery in Jackson County, Oreg., on plants of 3 years of age. Color references are made using The Royal Horticultural Society (London, England) Colour Chart, 2001 except where common terms of color are used.

For a comparison, several physical characteristics of the rose variety ‘KORtonetec’, a rose variety from the same inventor are compared to ‘KORfree-0006’ in Chart 1.
