Abstract

A new garden rose plant of the floribunda class which has abundant, lavender and purple 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: ‘POULcs006’.

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 parent ‘POULrine’ described and illustrated in U.S. Plant patent application Ser. No. 09/287,292 dated Mar. 31, 1999 now abandoned, and the male parent, an unnamed seedling. The two parents were crossed during the summer of 1991 and the resulting seeds were planted in a controlled environment in Fredensborg, Denmark. The new variety is named ‘POULcs006’.

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

- 1. The seed parent has medium pink flowers. ‘POULcs006’ has lavender and purple flowers.
- 2. The seed parent has little to no scent. ‘POULcs006’ has a strong rose scent.
- 3. The seed parent has 18 to 22 petals. ‘POULcs006’ has 45 petals.

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

- 1. The pollen parent has a strong pink bud color. ‘POULcs006’ has a mauve bud color.
- 2. ‘POULcs006’ has a stronger rose scent than the pollen parent.

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 mauve flowers;
- 2. Vigorous, but compact growth when propagated both as a budded rose and on its own roots;
- 3. Disease resistance;
- 4. Continuous flowering;
- 5. Exceptional scent.

This combination of qualities is not present in previously available commercial cultivars of this type, known to the inventors, and distinguish ‘POULcs006’ 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 1991 and conducted evaluations on the resulting seedlings in a controlled environment in Fredensborg, Denmark.

‘POULcs006’ was selected in the spring 1992 by the inventors as a single plant from the progeny of the aforementioned hybridization.

Asexual reproduction of ‘POULcs006’ by traditional budding and rooted cuttings was first done by L. Pernille and Mogens N. Olesen in their nursery in Fredensborg, Denmark in June, 1992. This initial and other subsequent asexual propagations conducted in controlled environments have demonstrated that the characteristics of ‘POULcs006’ 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 ‘POULcs006’.

Specifically illustrated in SHEET ONE:

FIG. 1.1; Cluster of open flowers, showing attachment of peduncles.;

FIG. 1.2; Flower buds at various stages of opening;

FIG. 1.3; Flower petals detached;

FIG. 1.4; Sepals, receptacle, and peduncle;

Specifically illustrated in SHEET TWO:

FIG. 2.1 Juvenile leaves, underneath and above view. Juvenile bare stem exhibiting anthocyanin thorns.

FIG. 2.2 Mature leaf and mature stem exhibiting thorns.

DETAILED DESCRIPTION OF THE VARIETY

The following is a description of ‘POULcs006’, as observed in its growth in a field nursery in Jackson County, Oreg. Observed plants are 3 years of age 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 ‘POULdahle’, a rose variety from the same inventors described and illustrated in U.S. Plant Pat. No. 13,451 dated Jan. 7, 2003 are compared to ‘POULcs006’ in Chart 1.
