Abstract

A new garden rose plant of the hybrid tea class which has abundant, deep 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: ‘POULen010’.

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 female parent plant, and a male parent ‘Harmusky’, non-patented. The two parents were crossed during the summer of 1996 and the resulting seeds were planted in a controlled environment in Fredensborg, Denmark. The new variety is named ‘POULen010’.

The new variety may be distinguished from its seed parent, by the following combination of characteristics:

- 1. Whereas seed parent has a light pink flower color, ‘POULen010’ has a light red to a deep pink flower color.
- 2. The seed parent has a 10 to 20 petals. ‘POULen010’ has 50 petals.
- 3. The seed parent has little to no scent, while ‘POULen010’ has a strong, floral scent.

The new variety may be distinguished from its pollen parent, ‘Harmusky’ by the following combination of characteristics:

- Whereas the pollen parent has a medium pink flower color, ‘POULen010’ has a light red to deep pink flower color.

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 deep pink flowers;
- 2. Vigorous, but compact growth when propagated both as a budded rose and on its own roots;
- 3. Disease resistance;
- 4. Exceptional fragrance.

This combination of qualities is not present in previously available commercial cultivars of this type, known to the inventors, and distinguish ‘POULen010’ 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 during winter 1996 and conducted evaluations on the resulting seedlings in a controlled environment in Fredensborg, Denmark.

‘POULen010’ was selected in the spring 1997 by the inventors as a single plant from the progeny of the aforementioned hybridization.

Asexual reproduction of ‘POULen010’ by traditional budding and rooted cuttings was first done by L. Pernille and Mogens N. Olesen in their nursery in Fredensborg, Denmark in June, 1997. This initial and other subsequent asexual propagations conducted in controlled environments have demonstrated that the characteristics of ‘POULen010’ 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 ‘POULen010’.

FIG. 2.4; Mature leaf.

DETAILED DESCRIPTION OF THE VARIETY

The following is a description of ‘POULen010’, as observed in its growth in a field nursery in Jackson County, Oreg. Observed plants are 3 years of age, grown on Rosa multiflora understock. 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 ‘POULdra’, a rose variety from the same inventors described and illustrated in U.S. Plant Pat. No. 12,999 dated Sep. 24, 2002 are compared to ‘POULen010’ in Chart 1.
