Abstract

A new floribunda garden rose plant which has abundant, pink and orange blend flowers and attractive foliage. This new and distinct variety has shown to be uniform and stable in the resulting generations from asexual propagation.

Description

Botanical classification: Rosa hybrida.

Variety denomination: ‘POULfl002’.

The present invention constitutes a new and distinct variety of garden rose plant which originated from a controlled crossing between a female parent ‘POULskov’, described and illustrated in U.S. Plant Pat. No. 9,062 issued on Feb. 28, 1995 and the male parent, an un-named, non-patented rose plant. The two parents were crossed during the summer of 1991 and the resulting seeds were planted in a controlled environment in Fredensborg, Denmark. The new variety is named ‘POULfl002’.

The new variety may be distinguished from its pollen parent, an un-named plant, by the following combination of characteristics:

1. The pollen parent has an average flower diameter of 60 mm when open, while that of ‘POULfl002’ is 65 mm.

2. After opening, the upper surface of the flower petals of the pollen parent are Red Purple Group 70C and 70D while the same on ‘POULfl002’ is Red Group 55D.

The new variety may be distinguished from its seed parent, ‘POULskov’ by the following combination of characteristics:

1. ‘POULskov’ has an average bloom diameter, when opened, of 60 to 80 mm, while ‘POULfl002’ is 65 mm.

2. General tonality of ‘POULskov’ is Red Group 49D to 56D, while ‘POULfl002’ is Red 52D.

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

1. Uniform and abundant pink orange blend flowers;

2. Vigorous, but compact growth when propagated both as a budded rose and on its own roots;

3. Disease resistance;

4. Continuous flowering;

5. Dark green glossy foliage.

This combination of qualities is not present in previously available commercial cultivars of this type, known to the inventors, and distinguish ‘POULfl002’ 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 during winter 1991 and conducted evaluations on the resulting seedlings in a controlled environment in Fredensborg, Denmark.

‘POULfl002’ was selected in the spring 1992 by the inventors as a single plant from the progeny of the aforementioned hybridization.

Asexual reproduction of ‘POULfl002’ by traditional budding and rooted cuttings was first done by L. Pernille and Mogens N. Olesen in their nursery in Fredensborg, Denmark in July, 1992. This initial and other subsequent asexual propagations conducted in controlled environments have demonstrated that the characteristics of ‘POULfl002’ are true to type and are transmitted from one generation to the next.

DETAILED DESCRIPTION OF THE VARIETY

The following is a description of ‘POULfl002’, as observed in its growth in a field nursery in Jackson County, Oreg. Observed plants are 4 years of age, budded on Rosa multiflora understock. 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 ‘POULskov’, a rose variety from the same inventors described and illustrated in U.S. Plant Pat. No. 9,062 and issued on Feb. 25, 1995 are compared to ‘POULfl002’ in Chart 1.
