Rose plant named ‘POULen005’

Abstract

A new garden rose plant of the hybrid tea class which has abundant, lavender 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: ‘POULen005’.

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 seed parent plant, an unnamed seedling, and issued on Sep. 5, 1995 and the male parent, ‘Evening star’, a non-patented variety. 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 ‘POULen005’.

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

• • 1. The seed parent has a white or near white flower color. ‘POULen005’ has a mauve flower color.
  • 2. The seed parent ha a medium growth height of 60 cm to 100 cm. ‘POULen005’ has a tall growth height of 100 cm to 150 cm.

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

• • 1. The pollen parent has a white flower color. ‘POULen005’ has a mauve flower color.
  • 2. The pollen parent has a slight fragrance. ‘POULen005’ has a strong floral fragrance.

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. Exceptional fragrance.

This combination of qualities is not present in previously available commercial cultivars of this type, known to the inventors, and distinguish ‘POULen005’ 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.

‘POULen005’ was selected in the spring 1992 by the inventors as a single plant from the progeny of the aformentioned hybridization.

Asexual reproduction of ‘POULen005’ by traditional budding and rooted cuttings was first done by L. Pernille and Mogens N. Olesen in their nursery in Fredensborg, Denmark in July, 1992. This initial and other subsequent asexual propagation conducted in controlled environments have demonstrated that the characteristics of ‘POULen005’ are true to type and are transmitted from one generation to the next.

DETAILED DESCRIPTION OF THE VARIETY

The following is a description of ‘POULen005’, 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 under 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 ‘POULen005’, a rose variety from the same inventors described and illustrated in U.S. Plant Pat. No. 13,293 and issued on Dec. 3, 2002 are compared to ‘POULen005’ in Chart 2.
