Abstract

A new rose plant that has abundant, red, white, and yellow flowers and attractive foliage. The variety successfully propagates from softwood cuttings and is suitable for year-round production in commercial glasshouses. 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: ‘Poulpah024’.

SUMMARY OF THE INVENTION

The present invention constitutes a new and distinct variety of rose plant which originated from a controlled crossing between the female seed parent, an unnamed seedling, and the male pollen parent, ‘Poulra020’, a non-patented variety from the same inventor. The two parents were crossed in 2001 and the resulting seeds were planted in a controlled environment. The new variety is named ‘Poulpah024’.

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

- 1. ‘Poulpah024’ normally has 90 flower petals, 10 to 15 of which are petaloids. The female parent has about 50 petals.
- 2. Flowers of ‘Poulpah024’ are red, blended with yellow and white stripes. The female parent has light pink flowers.
- 3. ‘Poulpah024’ flower bloom diameter is 55 to 60 mm. The female parent has a flower bloom diameter of 35 to 40 mm.

The new variety may be distinguished from the pollen parent ‘Poulra020’ by the following combination of characteristics:

- 1. ‘Poulpah024’ normally has 90 flower petals, 10 to 15 of which are petaloids. ‘Poulra020’ has approximately 25 to 35 petals.
- 2. ‘Poulpah024’ has an ovate bud form while the pollen parent has an ovoid to globular bud form.

The objective of the hybridization of this rose variety for commercial culture was to create a new and distinct variety with unique qualities, such as:

- 1. Uniform and abundant red, yellow, and white flowers;
- 2. Vigorous and compact growth;
- 3. Year-round flowering under glasshouse conditions;
- 4. Suitability for production from softwood cuttings in pots;
- 5. Durable flowers and foliage which make a variety suitable for distribution in the floral industry.

This combination of qualities is not present in previously available commercial cultivars of this type, known to the inventor, and distinguish ‘Poulpah024’ 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 and conducted evaluations on the resulting seedlings in a controlled environment in Fredensborg, Denmark.

‘Poulpah024’ was selected by the inventor as a single plant from the progeny of the hybridization in June 2002.

Asexual reproduction of ‘Poulpah024’ by vegetative cuttings and traditional budding was first done by Mogens N. Olesen in the nursery in Fredensborg, Denmark in April 2002. This initial and other subsequent propagations conducted in controlled environments have demonstrated that the characteristics of ‘Poulpah024’ are true to type and are transmitted from one generation to the next.

DETAILED DESCRIPTION OF THE VARIETY

The following is a description of ‘Poulpah024’, as observed in its growth in glasshouses in Odense, Denmark. Observed plants are 4 months of age. 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 ‘POULcub’, a rose variety from the same inventor described and illustrated in U.S. Plant patent application Ser. No. 10/647,010 dated Aug. 21, 2003, now abandoned, are compared to ‘Poulpah024’ in Chart 1.
