Climbing rose plant named ‘KORtempora’

A new and distinct variety of rose with long lasting, novel orange-red flowers, and attractive foliage with good disease resistance. It exhibits vigorous growth and an upright habit with abundant flowers. The new variety propagates well from cuttings and by grafting. This new and distinct variety has shown to be uniform and stable in the resulting generations from asexual propagation.

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 garden rose plant which was discovered in a cultivated area in July, 2005. The new rose variety resulted from a naturally occurring mutation of unknown causation on a branch of ‘KORromalu’, a non-patented rose. The new rose plant was asexually propagated for evaluation. This new and distinctive garden rose variety is named ‘KORtempora’.

SUMMARY OF THE INVENTION

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

    • 1. The color of ‘KORtempora’ is orange red while the color of ‘KORromalu’ is dark red.
    • 2. The flower size of ‘KORtempora’ is medium while the flower size of ‘KORromalu’ is large.

The new and distinct rose plant was selected due to its:

    • 1. Uniform growth and flowering;
    • 2. Abundant attractive, recurrent flowers;
    • 3. Attractive and abundant foliage; and
    • 3. 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 ‘KORtempora’ from all other varieties of which I am aware.

As part of the rose development program, Tim-Hermann Kordes asexually propagated the mutation by grafting and conducted evaluations and observations on the resulting plants in the inventor's nursery in Offenseth-Sparrieshoop, Germany. The first asexual propagation of ‘KORtempora’ was done by budding to seedling understocks in July, 2005 at the inventor's nursery in Offenseth-Sparrieshoop, Germany.

This initial and other subsequent propagations conducted in controlled environments demonstrate that ‘KORtempora’ 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, sepals, reproductive organs, flowers, leaves, prickles, and stems of ‘KORtempora’.

 DETAILED BOTANICAL DESCRIPTION

The following is a description of ‘KORtempora’, as observed growing in June, 2011 in a nursery in Jackson County, Oreg. on plants of 2 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 ‘KORtersen’, a non-patented rose variety from the same inventor is compared to ‘KORtempora’ in Chart 1.
