Abstract

A new garden rose plant which has abundant, light 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 classification: Rosa hybrida.

Variety denomination: ‘POULen003’.

SUMMARY OF THE INVENTION

The present discovery constitutes a new and distinct variety of a Hybrid Tea rose plant which was discovered in a cultivated area. The mutation resulted from ‘POULna’, a Hybrid Tea rose hybridized by the same inventors. (‘POULna’) is described and illustrated in U.S. Plant patent application Ser. No. 09/268,566, dated Mar. 15, 1999, abandoned. The new rose variety resulted from a naturally occurring mutation of unknown causation on a branch of ‘POULna’.

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

- 1. While ‘POULen003’ has exhibits light pink blooms, ‘POULna’ exhibits creamy white colored blooms.
- 2. While ‘POULen003’ exhibits basal petal spots of Green-Yellow Group 1D, ‘POULna’ exhibits basal petal spots of Yellow-Green Group 144D.

The rose plant of the present discovery has a unique combination of characteristics which are outstanding in the new variety and which distinguish it from all other varieties which we are aware of.

For example, the new variety has:

- 1. Uniform and abundant light pink flowers;
- 2. Disease resistance;
- 3. Vigorous growth;
- 4. Exceptional fragrance.

This combination of qualities is not present in previously available commercial cultivars of this type and distinguish ‘POULen003’ from all other varieties of which we are aware.

The resulting mutation was selected and evaluations were conducted on the resulting rose plants in a controlled environment.

Asexual reproduction of ‘POULen003’ by cuttings was first done by L. Pernille and Mogens N. Olesen in Fredensborg, Denmark, in 1996. This initial and other subsequent propagations have demonstrated that the characteristics of ‘POULen003’ 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 ‘POULen003’. Specifically illustrated in the first drawing:

- 1. Stem showing branching and the attachment of leaves, buds, and peduncle;
- 2. Flower bud, partially opened bud, and open bloom;
- 3. Flower petals, detached.

DETAILED DESCRIPTION OF THE VARIETY

The following is a description of ‘POULen003’, as 3 year old budded plants, observed in its growth in a field nursery in Jackson County, Oreg. 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 ‘POULheart’, a rose variety from the same inventors described and illustrated in the U.S. Plant patent application Ser. No. 09/270,179 dated Mar. 15, 1999, now abandoned, is compared to ‘POULen003’ in Chart 1.
