Abstract

A new Floribunda rose plant which has abundant, bronze 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: ‘POULymp’.

SUMMARY OF THE INVENTION

The present invention constitutes a new and distinct variety of Floribunda rose plant which originated from a controlled crossing between an unnamed seedling and an unnamed seedling. The two parents were crossed and the resulting seeds were planted in a controlled environment. The new variety is named ‘POULymp’.

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

- 1. The unnamed seed parent's flowers are yellow, where those of ‘POULymp’ are more golden bronze in color.
- 2. The growth of the unnamed seed parent is more vigorous than that of ‘POULymp’.

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

- 1. The unnamed pollen parent's flowers are yellow, where those of ‘POULymp’ are a golden bronze color.
- 2. The growth of the pollen parent is more vigorous than that of ‘POULymp’.

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

- 1. Uniform and abundant 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 and distinguish ‘POULymp’ 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 and conducted evaluations on the resulting seedlings in a controlled environment in Fredensborg, Denmark. ‘POULymp’ was selected by the inventors as a single plant from the progeny of the hybridization in Fredensborg, Denmark, in the spring of 1996.

Asexual reproduction of ‘POULymp’ by cuttings and traditional budding was first done by L. Pernille and Mogens N. Olesen in their nursery in Fredensborg, Denmark in . This initial and other subsequent propagations conducted in controlled environments have demonstrated that the characteristics of ‘POULymp’ 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, stems, and a plant of ‘POULymp’. Specifically illustrated in SHEET 1:

1. Stem or entire plant showing branching and the attachment of leaves, buds, and peduncles;

2. Flower bud, partially opened bud, and open bloom;

3. Flower petals, detached;

4. Sepals, receptacle, and pedicel;

5. Flowering stem as well as a bare stem exhibiting thorns;

6. Leaves.

DETAILED DESCRIPTION OF THE VARIETY

The following is a description of ‘POULymp’, as observed in its growth in glasshouses in Half Moon Bay, Calif. Observed plants are 3 months in age. Color references are made using 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 ‘POULsail’, a Compact Floribunda rose variety from the same inventors described and illustrated in U.S. Plant patent application Ser. No. 09/140,630 dated Aug. 26, 1998, are compared to ‘POULymp’ in Chart 1.
