Compact floribunda rose plant named `POULjoey`

Abstract

A new compact floribunda rose plant which has abundant 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

SUMMARY OF THE INVENTION

The present invention constitutes a new and distinct variety of compact 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 `POULjoey`.

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

1. The unnamed seedling is a yellow patio rose and `POULjoey` is a compact floribunda with Red and Orange-Red colored flowers.

2. The unnamed seedling has smaller flowers and lower growth than `POULjoey`.

3. The unnamed seedling is an offspring of `Ruimired`, U.S. Plant Pat. No. 5,770 and Texas, U.S. Plant Pat. No. 6,261.

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

1. The unnamed seedling is a warm yellow patio rose and `POULjoey` is a compact floribunda with Red and Orange-Red colored flowers.

2. The flowers, growth, and size of the plant of the unnamed seedling is smaller than `POULjoey`.

The objective of the hybridization of this rose variety 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 or by traditional budding;

5. Durable flowers and foliage which make a variety suitable for distribution in the floral and nursery industry.

This combination of qualities is not present in previously available commercial cultivars of this type and distinguish `POULjoey` 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.

`POULjoey` was selected by the inventors as a single plant from the progeny of the hybridization in June 1990.

Asexual reproduction of `POULjoey` by cuttings was first done in their nursery in Fredensborg, Denmark in March 1991 and by traditional budding in their nursery in Fredensborg, Denmark in August 1991 by L. Pernille and Mogens N. Olesen. This initial and other subsequent propagations conducted in controlled environments have demonstrated that the characteristics of `POULjoey` 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 `POULjoey`. Specifically illustrated in SHEET 1:

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

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

3. Flower petals, detached;

4. Sepals 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 `POULjoey`, as observed in its growth in our nursery in Fredensborg, Denmark, as in a field nursery in Jackson County, Ore. 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 `POULdace`, a rose variety from the same inventors described and illustrated in U.S. Plant patent application Ser. No. 09/165,408 dated Oct. 2, 1998 are compared to `POULjoey` in Chart 1.
