Abstract

A new garden rose plant of the floribunda class which has abundant pink 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: ‘POULcs011’.
SUMMARY OF THE INVENTION
The present invention constitutes a new and distinct variety of garden rose plant of the floribunda class which originated from a controlled crossing between a female seed parent, an unnamed seedling, and a male pollen parent plant named ‘POULskov’, described and illustrated in U.S. Plant Pat. No. 9,062 issued on Feb. 28, 1995. The two parents were crossed during the summer of 1992 and the resulting seeds were planted in a controlled environment in Fredensborg, Denmark. The new variety is named ‘POULcs011’.
The new variety may be distinguished from its seed parent, by the following combination of characteristics:
1. The seed parent has fewer than 20 petals. ‘POULcs011’ has a petal count of 20 to 40.
2. The see parent ha a Red-Purple bud color. The same of ‘POULcs011’ is Red Group 46A.
The new variety may be distinguished from its pollen parent, ‘POULskov’ by the following combination of characteristics:
1. The pollen parent has a soft pink coloration while ‘POULcs011’ is an apricot blend.
2. The pollen parent has a petal count of 48 to 62 whereas ‘POULcs011’ has 28.
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 apricot flowers;
2. Continuous flowering;
3. Vigorous, but compact growth when propagated both as a budded rose and on its own roots;
4. Strong rose fragrance;
5. Disease resistance.
This combination of qualities is not present in previously available commercial cultivars of this type, known to the inventors, and distinguish ‘POULcs011’ 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 1992 and conducted evaluations on the resulting seedlings in a controlled environment in Fredensborg, Denmark.
‘POULcs011’ was selected in the spring 1993 by the inventors as a single plant from the progeny of the aforementioned hybridization.
Asexual reproduction of ‘POULcs011’ by traditional budding and rooted cuttings was first done by L. Pernille and Mogens N. Olesen in their nursery in Fredensborg, Denmark in July, 1993. This initial and other subsequent asexual propagations conducted in controlled environments have demonstrated that the characteristics of ‘POULcs011’ 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 ‘POULcs011’.
Specifically illustrated in SHEET 1:
FIG. 1.1; Open flower, stem showing cluster of open flowers, branching, and the attachment of leaves, buds, and peduncles;
FIG. 1.2; Flower bud closed, flower bud as sepals unfold, and partially open;
FIG. 1.3; Flower petals, detached;
FIG. 1.4; Sepals, receptacle, and peduncle;
Specifically illustrated in SHEET 2:
FIG. 2.1; Mature leaf and juvenile leaf.
FIG. 2.2; Bare stem exhibiting thorns.
DETAILED DESCRIPTION OF THE VARIETY
The following is a description of ‘POULcs011’, as observed in its growth in a field nursery in Jackson County, Oreg. Observed plants are 3 years of age, grown 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 ‘POULkalm’, a rose variety from the same inventors described and illustrated in U.S. Plant patent application Ser. No. 10/339,733 date Feb. 10, 2003 are compared to ‘POULcs011’ in Chart 1.
