Rose plant named ‘POULcs008’

Abstract

A new garden rose plant of the floribunda class which has abundant, yellow-apricot 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: ‘POULcs008’.

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, an unnamed seedling, and the male pollen parent, ‘POULurt’ described and illustrated in U.S. Plant Pat. No. 9,637 issued Sep. 3, 1996. The two parents were crossed during the summer of 1993 and the resulting seeds were planted in a controlled environment in Fredensborg, Denmark. The new variety is named ‘POULcs008’.

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

• • 1. The seed parent has an orange red flower color while ‘POULcs008’ has a yellow orange blend flower color.
  • 2. The seed parent has a wild rose scent whereas, ‘POULcs008’ has little or no scent.
  • 3. The seed parent has an average height of 50 cm, whereas, the same of ‘POULcs008’ ranges from 60 to 100 cm.

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

• • 1. The pollen parent has a range from 15 to 25 petals whereas ‘POULcs008’ has a range from 25 to 30 petals.
  • 2. The pollen parent has a small flower size 4.5 cm, while ‘POULcs008’ has a medium flower size between 8 cm and 10 cm.

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 yellow-apricot flowers;
  • 2. Vigorous, but compact growth when propagated both as a budded rose and on its own roots;
  • 3. Disease resistance.

This combination of qualities is not present in previously available commercial cultivars of this type, known to the inventors, and distinguish ‘POULcs008’ 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 1993 and conducted evaluations on the resulting seedlings in a controlled environment in Fredensborg, Denmark.

‘POULcs008’ was selected in the spring 1994 by the inventors as a single plant from the progeny of the aforementioned hybridization.

Asexual reproduction of ‘POULcs008’ by traditional budding and rooted cuttings was first done by L. Pernille and Mogens N. Olesen in their nursery in Fredensborg, Denmark in July, 1994. This initial and other subsequent asexual propagations conducted in controlled environments have demonstrated that the characteristics of ‘POULcs008’ are true to type and are transmitted from one generation to the next.

DETAILED DESCRIPTION OF THE VARIETY

The following is a description of ‘POULcs008’, as observed in its growth in a field nursery in Jackson County, Oreg. Observed plants are 3 years of age. 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 ‘POULcs003’, a rose variety from the same inventors described and illustrated in U.S. Plant patent application Ser. No. 10/342,697 dated Jan. 14, 2003, are compared to ‘POULcs008’ in Chart 1.
