Compact floribunda rose plant named ‘Poulpal021’

Abstract

A new garden rose plant of the floribunda rose class which has abundant, red 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: ‘Poulpal021’.

SUMMARY OF THE CLAIMED PLANT

The present invention constitutes a new and distinct variety of garden rose plant that originated from a controlled crossing between the female seed parent, an unnamed seedling, and the male pollen parent, ‘Poulgrad’ described in U.S. Pat. No. 11,610.

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 ‘Poulpal021’.

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

• • 1. The seed parent has medium pink flowers. ‘Poulpal021’ has dark red flowers.
  • 2. The seed parent has a petal count of 25 to 40 petals, while ‘Poulpal021’ has 180 petals.

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

• • 1. General tonality for ‘Poulgrad’ open flower color is Red Group 53A with intonations of 46A. ‘Poulpal021’ is Red Group 53A with intonations of Red-Purple Group 60A.
  • 2. ‘Poulgrad’ has a flower diameter of 35 mm. ‘Poulpal021’ flowers are is 42 mm in diameter.
  • 3. ‘Poulpal21’ has more than double the amount of flower petals than ‘Poulgrad’.

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 red flowers which do not fade as flowers mature;
  • 2. Vigorous, but compact growth;
  • 3. Disease resistance;
  • 4. High petal count.

This combination of qualities is not present in previously available commercial cultivars of this type, known to the inventors, and distinguish ‘Poulpal021’ 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 1997 and conducted evaluations on the resulting seedlings in a controlled environment in Fredensborg, Denmark.

‘Poulpal021’ was selected in the spring of 1998 by the inventor as a single plant from the progeny of the aforementioned hybridization.

Asexual reproduction of ‘Poulpal021’ 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 ‘Poulpal021’ are true to type and are transmitted from one generation to the next.

DETAILED DESCRIPTION OF THE VARIETY

The following is a description of ‘Poulpal021’, as observed in its growth in a field nursery in Jackson County, Oreg. Observed plants are 3 years of age, and were grown on Rosa multiflora understock. Color references are made using The Royal Horticultural Society (London, England) Colour Chart, 2001, except where common terms of color are used.

For a comparison, several physical characteristics of the rose variety ‘Poulchris’, a rose variety from the same inventors described and illustrated in U.S. Plant Pat. No. 11,151 issued Dec. 14, 1999, are compared to ‘Poulpal021’ in Chart 1.
