Abstract

A new garden rose plant of the compact hybrid tea class which has abundant, 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 designation: Rosa hybrid.

Variety denomination: ‘Poulpal031’.

SUMMARY OF THE INVENTION

The present invention constitutes a new and distinct variety of garden rose plant which originated from a controlled crossing between the female seed parent, an unnamed seedling, and the male pollen parent, an unnamed seedling.

The two parents were crossed during the summer of 2005 and the resulting seeds were planted in a controlled environment in Fredensborg, Denmark. The new variety, named ‘Poulpal031’, originated as a single seedling from the stated cross.

The new variety may be distinguished from its female seed parent primarily by the flower color. The seed parent has yellow flowers while the new variety has orange blend flowers.

The new variety may be distinguished from its male pollen parent primarily by flower color. The pollen parent has yellow flowers while the new variety has orange blend flowers.

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 orange blend flowers;
- 2. Vigorous, but compact growth when propagated both as a budded rose and on its own roots;
- 3. Exceptional disease resistance.

This combination of qualities is not present in previously available commercial cultivars of this type, known to the inventor, and distinguish ‘Poulpal031’ from all other varieties of which we are aware.

As part of the rose development program, Mogens N. Olesen germinated the seeds from the aforementioned hybridization during winter of 2005 and conducted evaluations on the resulting seedlings in a controlled environment in Fredensborg, Denmark. ‘Poulpal031’ was selected in the spring of 2006 by the inventor as a single plant from the progeny of the aforementioned hybridization.

Asexual reproduction of ‘Poulpal031’ by traditional budding and rooted cuttings was first done by Mogens N. Olesen in the nursery in Fredensborg, Denmark in July, 2006. This initial and other subsequent asexual propagations conducted in controlled environments have demonstrated that the characteristics of ‘Poulpal031’ 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 ‘Poulpal031’. Specifically illustrated in the drawing are:

FIG. 1; Flowers at various stages of opening and sepals detached;

FIG. 2; Cluster of flowers on branch showing attachment of flower buds and flower petals detached;

FIG. 3; Flower petals detached, reproductive flower parts, and flower side view upon opening; and

FIG. 4; Leaves and stem exhibiting thorns.

DETAILED DESCRIPTION OF THE VARIETY

The following is a description of ‘Poulpal031’, as observed in its growth in in a field nursery in Benton County, Oreg. Observed plants are 21 months of age, and were grown from own root. Color references are made using The Royal Horticultural Society (London, England) Colour Chart, 2001, except where common terms of color are used.

For a comparison, several physical characteristics of the rose variety ‘Poulymp’, U.S. Plant Pat. No. 16,744 are compared to ‘Poulpal031’ in Chart 1.
