Miniature rose plant named ‘Poulpah034’

Abstract

A new miniature rose plant that has abundant, light pink flowers with pale orange hues 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 designation: Rosa hybrid.

Variety denomination: ‘Poulpah034’.

SUMMARY OF THE INVENTION

The present discovery constitutes a new and distinct variety of compact floribunda miniature rose plant which was discovered in a cultivated area. The new rose variety resulted from a naturally occurring mutation of unknown causation on a branch of ‘Poulac015’, described and illustrated in U.S. Plant Pat. No. 15,171. The resulting mutation was selected and evaluations were conducted on the resulting rose plants in a controlled environment.

The rose plant of the present discovery has a unique combination of characteristics which are outstanding in the new variety and which distinguish it from the original rose as well as all other varieties which we are aware of. For example, the general tonality of flower color for the original rose, ‘Poulac015’, is described as being Red-Purple Group 63B to 57C. The general tonality of flower color for the claimed plant ‘Poulpah034’ is described as being Red 49 D becoming Orange 27 D as flowers mature. Additionally, the bloom diameter for the plant variety ‘Poulpah034’ is greater than the original rose, ‘Poulac015’.

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

• • 1. Uniform and abundant light pink flowers with pale orange hues;
  • 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 ‘Poulpah034’ from all other varieties of which we are aware.

Asexual reproduction of ‘Poulpah034’ by vegetative cuttings was first done by Mogens N. Olesen in Fredensborg, Denmark, in July of 1999. This initial and other subsequent propagations have demonstrated that the characteristics of ‘Poulpah034’ are stable and reproduced true to type in successive generations of asexual reproduction.

DETAILED DESCRIPTION OF THE VARIETY

The following is a description of ‘Poulpah034’, as observed in its growth in a glasshouse located in Fredensborg, Denmark. Observed plants are 4 months of age and were cultivated in 12 cm pots. 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 ‘Poulpah026’, described and illustrated in U.S. Plant Pat. No. 16,577 are compared to ‘Poulpah034’ in Chart 1.
