Miniature rose plant named ‘Poulpah053’

Abstract

A new miniature rose plant that has abundant, red 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 designation: Rosa hybrid.

Variety denomination: ‘Poulpah053’.

SUMMARY OF THE INVENTION

The present invention constitutes a new and distinct variety of miniature rose plant which originated from a controlled crossing between the female seed parent, an unnamed seedling, and the male pollen parent, an unnamed seedling.

The two parents were crossed during the summer of 2006 and the resulting seeds were planted in a controlled environment in Fredensborg, Denmark. The new variety, named ‘Poulpah053’, originated as a single seedling from the stated cross.

The new variety may be distinguished from its female seed parent primarily by flower color. The female seed parent has pink flowers while the new variety has red flowers.

The new variety may be distinguished from its male pollen parent primarily by flower color. The male parent has medium red flowers while the new variety has red flowers.

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 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 ‘Poulpah053’ 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. ‘Poulpah053’ was selected by the inventor as a single plant from the progeny of the hybridization in 2006.

Asexual reproduction of ‘Poulpah053’ by cuttings and traditional budding was first done by Mogens N. Olesen in the nursery in Fredensborg, Denmark in June 2007. This initial and other subsequent propagations conducted in controlled environments have demonstrated that the characteristics of ‘Poulpah053’ are true to type and are transmitted from one generation to the next.

BRIEF DESCRIPTION OF THE DRAWING

The accompanying color illustration shows as true as is reasonably possible to obtain in color photographs of this type, the typical characteristics of the buds, flowers, leaves, and stems of ‘Poulpah053’.

DETAILED DESCRIPTION OF THE VARIETY

The following is a description of ‘Poulpah053’, as observed in its growth in glasshouses in Burlington, Ontario, Canada. Observed plants are 3 months of age and were cultivated in 15 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 ‘Poulhi021’, U.S. Plant Pat. No. 15,853. are compared to ‘Poulpah053’ in Chart 1.
