Abstract

A new garden rose plant of the hybrid tea 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 hybrid.
Variety denomination: ‘Poulen012’.
SUMMARY OF THE INVENTION
The present invention constitutes a new and distinct variety of garden rose plant which originated from a controlled crossing between a female parent ‘Poulsyng’, described and illustrated in the abandoned U.S. Plant patent application Ser. No. 09/268,299 dated Mar. 16, 1999, the male parent, an unnamed seedling. The two parents were crossed during the summer of 1995 and the resulting seeds were planted in a controlled environment in Fredensborg, Denmark. The new variety is named ‘Poulen012’.
The new variety may be distinguished from its female seed parent, ‘Poulsyng’ by the following combination of characteristics:
1. While the seed parent ‘Poulsyng’ has flower petals which are Red Group 36D, ‘Poulen012’ has flower petals which are White Group 155B with a strong overlay of Reg Group 36D to Reg Group 49D.
2. While the seed parent ‘Poulsyng’ has 34 to 40 petals ‘Poulen012’ has 45 to 50 petals.
3. While ‘Poulsyng’ has basal petal spots which are Yellow Group 3B in color, ‘Poulen012’ has petal spots which are Yellow Group 6C in color.
The new variety may be distinguished from its pollen parent, an unnamed seedling, by the following combination of characteristics:
1. No petal spots observed on the pollen parent. ‘Poulen012’ has Yellow Group 6C petal spots.
2. Flowers of the pollen parent produce less fragrance than flowers of ‘Poulen012’.
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 flowers;
2. Vigorous, but compact growth when propagated both as a budded rose and on its own roots;
3. Disease resistance;
4. Exceptional flower fragrance.
This combination of qualities is not present in previously available commercial cultivars of this type, known to the inventors, and distinguish ‘Poulen012’ from all other varieties of which are aware.
As part of their rose development program, L. Pernille Olesen and Mogens N. Olesen germinated the seeds from the aformentioned hybridization during winter of 1995 and conducted evaluations on the resulting seedlings in a controlled environment in Fredensborg, Denmark.
‘Poulen012’ was selected in the spring 1996 by the inventors as a single plant from the progeny of the aforementioned hybridization.
Asexual reproduction of ‘Poulen012’ by traditional budding and rooted cuttings was first done by L. Pernille and Mogens N. Olesen in their nursery in Fredensborg, Denmark in July, 1996. This initial and other subsequent asexual propagations conducted in controlled environments have demonstrated that the characteristics of ‘Poulen012’ are true to type and are transmitted from one generation to the next.

DETAILED DESCRIPTION OF THE VARIETY
The following is a description of ‘Poulen012’, as observed in its growth in a field nursery in Jackson County, Oreg. Observed plants are 3 years of age. Plants were 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 ‘Poulen009’, a rose variety from the same inventors described and illustrated in U.S. Plant patent application Ser. No. 10/742,402 dated Dec. 22, 2003 are compared to ‘Poulen012’ in Chart 1.
