USPP12552P2 - Climbing rose variety ‘POULnorm’ - Google Patents

Abstract

A new garden rose plant which has abundant, large red, fragrant flowers and attractive foliage. 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 garden rose plant which originated from a controlled crossing between an unnamed seedling (non-patented) and ‘Norita’ (non-patented.) The two parents were crossed and the resulting seeds were planted in a controlled environment. The new variety is named ‘POULnorm’.

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

1. The seed parent has pink blooms; whereas, ‘POULnorm’ has red blooms;

2. The habit of the seed parent is shrubby and compact; whereas, ‘POULnorm’ is a climber;

3. The petalage of the seed parent is semi-double, whereas ‘POULnorm’ has very double and much Larger blooms.

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

1. The blooms of the pollen parent are a darker red when compared to the blooms of ‘POULnorm’;

2. The pollen parent is a hybrid tea rose with a shruby habit; whereas, ‘POUnorm’ has the growth habit of a climber;

3. The petalage of the pollen parent is double compared to ‘POULnorm’ which has larger blooms with very double petalage.

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

1. Uniform and abundant flowers;

2. Vigorous growth;

3. Fragrant flowers;

4. Disease resistance.

This combination of qualities is not present in previously available commercial cultivars of this type and distinguishes ‘POULnorm’ 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.

‘POULnorm’ was selected in spring, 1986 by the inventors as a single plant from the progeny of the aforementioned hybridization.

Asexual reproduction of ‘POULnorm’ by traditional budding was first done by L. Pernille and Mogens N. Olesen in August 1986. This initial and other subsequent propagations conducted in controlled environments have demonstrated that the characteristics of ‘POULnorm’ 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 ‘POULnorm’. Specifically illustrated in SHEET 1:

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

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

3. Flower petals, detached;

Specifically illustrated in SHEET 2:

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 ‘POULnorm’, as observed in its outdoor growth in a field nursery in Jackson County, Oreg. Observations were conducted duuring September, 1998 on plants aged eighteen months. 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 ‘POULisab’, a hybrid tea rose variety from the same inventors described and illustrated in U.S. Plant patent application Ser. No. 09/270,177 filed Mar. 15, 1999 are compared to ‘POULnorm’ in Chart 1.
