Description

Botanical designation: Rosa hybrida.

Variety denomination: ‘Poulpah105’.

SUMMARY OF THE INVENTION

The present invention constitutes a new and distinct variety of 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 2012 and the resulting seeds were planted in a controlled environment in Fredensborg, Denmark. The new variety, named ‘Poulpah105’, 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 male pollen parent plant has red flowers while the new variety has red-pink and white striped flowers. The female seed parent plant has near white flowers while the new variety has red and white striped flowers.

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

    • 1. Uniform and abundant red-pink and white striped flowers;
    • 2. Vigorous, but compact growth when propagated 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 ‘Poulpah105’ 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 2012 and conducted evaluations on the resulting seedlings in a controlled environment in Fredensborg, Denmark. ‘Poulpah105’ was selected in the spring of 2013 by the inventor as a single plant from the progeny of the aforementioned hybridization.

Asexual reproduction of ‘Poulpah105’ by rooted cuttings was first done by Mogens N. Olesen in the nursery in Fredensborg, Denmark in July, 2013. This initial and other subsequent asexual propagations conducted in controlled environments have demonstrated that the characteristics of ‘Poulpah105’ are true to type and are transmitted from one generation to the next.

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 ‘Poulpah105’. Specifically illustrated in the drawing are open flowers viewed from the side and above, flower petals and sepals detached revealing reproductive flower parts and receptacle, bare stems, mature and juvenile leaves, and a cluster of flower buds. Plants shown are 4 months of age.

DETAILED DESCRIPTION OF THE VARIETY

The following is a description of ‘Poulpah105’, as observed in its growth in a controlled environment greenhouse in Odense Denmark. Observed plants are 4 months old and were grown on their own roots in 19 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 ‘Poulty019’, U.S. Plant Pat. No. 26,051 are compared to ‘Poulpah105’ in Chart 1.
