Abstract

A new garden rose plant of the Floribunda class which has abundant, pink flowers and attractive foliage. This new and distinct variety has shown to be uniform and stable in the resulting generations from asexual propagation.

Description

Botanical designation: Rosa hybrid.

Variety denomination: ‘Poulnap002’.

SUMMARY OF THE INVENTION

The present invention constitutes a new and distinct variety of garden rose plant which originated from a controlled crossing between the female seed parent, an unnamed seedling, and the male pollen parent, also an unnamed seedling.

The two parents were crossed during the summer of 2000 and the resulting seeds were planted in a controlled environment in Fredensborg, Denmark. The new variety, named ‘Poulnap002’, originated as a single seedling from the stated cross.

The new variety may be distinguished from its female seed parent and male pollen parent primarily by flower color. While the claimed plant has flowers which are Red Group 43C, the female seed parent has flowers which are Red Group 36B and Orange Group 29D blend. The male pollen parent has flowers which are Red Group 54D. Furthermore, the male pollen parent is 100 to 150 cm in height, while the claimed plant is about 60 to 100 cm in height.

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

- 1. Uniform and abundant pink flowers;
- 2. Vigorous, but compact growth when propagated both as a budded rose and on its own roots; and
- 3. Exceptional disease resistance.

This combination of qualities is not present in previously available commercial cultivars of this type, known to the inventor, and distinguish ‘Poulnap002’ from all other varieties of which we are aware.

As part of the rose development program, Mogens N. Olesen germinated the seeds from the aforementioned hybridization during winter of 2000 and conducted evaluations on the resulting seedlings in a controlled environment in Fredensborg, Denmark. ‘Poulnap002’ was selected in the spring of 2001 by the inventor as a single plant from the progeny of the aforementioned hybridization.

Asexual reproduction of ‘Poulnap002’ by traditional budding and rooted cuttings was first done by Mogens N. Olesen in the nursery in Fredensborg, Denmark in July, 2001. This initial and other subsequent asexual propagations conducted in controlled environments have demonstrated that the characteristics of ‘Poulnap002’ are true to type and are transmitted from one generation to the next.

DESCRIPTION OF THE DRAWING

The accompanying color illustrations show 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 ‘Poulnap002’.

Specifically illustrated in FIG. 1 are a flower bud, open flowers, petals detached, and reproductive flower parts.

Illustrated in FIG. 2 are mature and juvenile leaves and stems.

DETAILED DESCRIPTION OF THE VARIETY

The following is a description of ‘Poulnap002’, as observed in its growth in in a field nursery in Marion County, Oreg. Observed plants are 3 years of age, and were grown on their own roots. 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 ‘Poulriber’, U.S. Plant Pat. No. 12,902 are compared to ‘Poulnap002’ in Chart 1.
