Description
SUMMARY OF THE INVENTION

The present invention constitutes a new and distinct variety of garden rose plant which originated from a controlled crossing between an unnamed seedling (non-patented) and ‘Kordes Brilliant’ (non-patented). The two parents were crossed and the resulting seeds were planted in a controlled environment. The new variety is named ‘POULtika’.

The new rose may be distinguished from its seed parent, an unnamed seedling, by the following combination of characteristics:

1. The habit of the seed parent is a compact shrub; whereas, ‘POULtika’ is a climbing rose.

2. The petalage of the seed parent is semi-double; whereas, ‘POULtika’ blooms are double;

The new variety may be distinguished from its pollen parent, ‘Kordes Brilliant’ created by the same inventors, by the following combination of characteristics:

1. The flower color of the pollen parent is orange-red, while ‘POULtika's’ flowers are light pink;

2. The foliage of the pollen parent is medium green, compared to ‘POULtika's’ dark green foliage.

The objective of the hybridization of this rose variety for nursery and garden use was to create a new and distinct variety with unique qualities, such as:

1. Uniform and abundant flowers;

2. Vigorous growth;

3. Disease resistance;

4. Large cupped flower form.

This combination of qualities is not present in previously available commercial cultivars of this type and distinguishes ‘POULtika’ from all other varieties of which we are aware.

As part of their rose development program, L. Pernille Olesen and Mogens N. Olesen germinated the seeds from the aforementioned hybridization and conducted evaluations on the resulting seedlings in a controlled environment in Fredensborg, Denmark.

‘POULtika’ was selected in spring 1988 by the inventors as a single plant from the progeny of the aforementioned hybridization.

Asexual reproduction of ‘POULtika’ by traditional budding was first done by L. Pernille and Mogens N. Olesen in August, 1988. This initial and other subsequent propagations conducted in controlled environments have demonstrated that the characteristics of ‘POULtika’ are true to type and are transmitted from one generation to the next.

BRIEF DESCRIPTION OF THE DRAWING

The accompanying color illustration 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 ‘POULtika’. Specifically illustrated in Sheet 1:

1. Stem showing branching and the attachment of leaves, buds, and peduncles;

2. Flower bud, partially opened bud, and open bloom;

3. Flower petals, detached;

4. Sepals, receptacle, and pedicel;

5. Flowering stem as well as a bare stem exhibiting thorns;

6. Leaves.

DETAILED DESCRIPTION OF THE VARIETY

The following is a description of ‘POULtika’, as observed in its outdoor growth in a field nursery in Jackson County, Oregon. Observations were conducted during September, 1998, on an 18 month old plant. Color references are made using The Royal Horticultural Society (London, England) Colour Chart, 1995, except where common terms of color are used.

For a comparison, several physical characteristics of the rose variety ‘POULclimb’, a climbing rose variety from the same inventors described and illustrated in U.S. Plant Pat. No. 10,639 and issued on Oct. 13, 1998 are compared to ‘POULtika’ in Chart 1.
