Shrub rose plant named ‘Poultc005’

Abstract

A new garden rose plant of the shrub 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 classification: Rosa hybrid.

Variety denomination: ‘Poultc005’.

SUMMARY OF THE INVENTION

The present invention constitutes a new and distinct variety of garden rose plant that originated from a controlled crossing between the female parent plant, an unnamed seedling, and the male pollen parent plant, an unnamed seedling. The two parents were crossed during the summer of 1997 and the resulting seeds were planted in a controlled environment in Fredensborg, Denmark. The new variety is named ‘Poultc005’.

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

• • 1. ‘Poultc005’ has a taller growth habit than the female parent plant.
  • 2. ‘Poultc005’ exhibits flowers with a smaller diameter than those of the female parent.
  • 3. Flowers of ‘Poultc005’ have fewer flower petals than those of the female parent.

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

• • 1. The pollen parent has darker pink flowers than those of ‘Poultc005’.
  • 2. The pollen parent plant has larger flowers than ‘Poultc005’.

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;
  • 3. Disease resistance;
  • 4. Suitability for growth in a container.

This combination of qualities is not present in previously available commercial cultivars of this type, known to the inventors, and distinguish ‘Poultc005’ 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 1996 and conducted evaluations on the resulting seedlings in a controlled environment in Fredensborg, Denmark.

‘Poultc005’ was selected in the spring 1998 by the inventor as a single plant from the progeny of the aforementioned hybridization.

Asexual reproduction of ‘Poultc005’ by traditional budding and rooted cuttings was first done by Mogens N. Olesen in the nursery in Fredensborg, Denmark in July, 1998.

This initial and other subsequent asexual propagations conducted in controlled environments have demonstrated that the characteristics of ‘Poultc005’ are true to type and are transmitted from one generation to the next.

DETAILED DESCRIPTION OF THE VARIETY

The following is a description of ‘Poultc005’, 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 ‘Poulor’, a rose variety from the same inventors described and illustrated in U.S. Plant Pat. No. 12,511 dated Apr. 2, 2002, are compared to ‘Poultc005’ in Chart 1.
