Compact floribunda rose plant named ‘Poulpal067’

Abstract

A new garden rose plant of the compact floribunda class which has abundant, yellow 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: ‘Poulpal067’.

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, also an unnamed seedling. Both of the parent varieties are non-patented.

The two parents were crossed during the summer of 2009 and the resulting seeds were planted in a controlled environment in Fredensborg, Denmark. The new variety, named ‘Poulpal067’, originated as a single seedling from the stated cross.

The new variety may be distinguished from its male pollen parent and female seed parent primarily by the following characteristics. The female pollen parent is very compact growing to 20 cm in height, while the new variety grows to 40 cm in height. The male pollen parent produces flowers singly or cluster of 3 flower buds per stem, while the new variety produces flowers in clusters of 5 to 10 flower buds.

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 yellow 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 ‘Poulpal067’ 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 2009 and conducted evaluations on the resulting seedlings in a controlled environment in Fredensborg, Denmark. ‘Poulpal067’ was selected in the spring of 2010 by the inventor as a single plant from the progeny of the aforementioned hybridization.

Asexual reproduction of ‘Poulpal067’ by traditional budding and rooted cuttings was first done by Mogens N. Olesen in the nursery in Fredensborg, Denmark in July, 2010. This initial and other subsequent asexual propagations conducted in controlled environments have demonstrated that the characteristics of ‘Poulpal067’ are true to type and are transmitted from one generation to the next.

DESCRIPTION OF THE DRAWING

The accompanying color illustrations show 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 ‘Poulpal067’.

Specifically illustrated in FIG. 1 is an open flower, flower petals detached, cluster of open flowers on a branch, bare stem, compound leaf, reproductive flower parts, and sepals detached.

Specifically illustrated in FIG. 2 is a cluster of open flowers.

Plants shown are 1 year of age.

DETAILED DESCRIPTION OF THE VARIETY

The following is a description of ‘Poulpal067’, as observed in its growth in Odense Denmark. Observed plants are 1 year of age, and were grown on their own roots in 23 cm containers. 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 ‘Poulsiana’, U.S. Plant Pat. No. 11,638 are compared to ‘Poulpal067’ in Chart 1.
