Abstract

A new miniature rose plant which has abundant, coral-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

SUMMARY OF THE INVENTION
Classification:
Botanical.—Rosa hybrida ‘POULgo003’.
Commercial.—Miniature.
The present invention constitutes a new and distinct variety of miniature rose plant which originated from a controlled crossing between an unnamed and unpatented variety, and ‘POULrijk’, described and illustrated in U.S. Plant Patent application Ser. No. 09/261,445, dated Mar. 3, 1999. The two parents were crossed during the summer of 1994 and the resulting seeds were planted in a controlled environment in Fredensborg, Denmark. The new variety is named ‘POULgo003’.
The new variety may be distinguished from its seed parent, an unnamed seedling, by the following combination of characteristics:
1. ‘POULgo003’ has coral-pink flowers, whereas the seed parent has pink flowers.
2. ‘POULgo003’ exhibits pendulant to procumbent growth, while the seed parent has compact, upright growth.
The new rose may be distinguished from its pollen parent, ‘POULrijk’, by the following combination of characteristics:
1. ‘POULrijk’ is a ground cover shrub rose, whereas ‘POULgo003’ is a miniature rose.
2. ‘POULrijk’ has a spreading habit while ‘POULgo003’ exhibits a procumbent habit.
3. ‘POULrijk’ has semi-double, pure pink flowers, while ‘POULgo003’ has double, coral-pink 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 flowers;
2. Vigorous, but compact growth when propagated by cuttings;
3. Disease resistance;
4. A miniature rose suitable for use in hanging basket containers in the nursery industry.
This combination of qualities is not present in previously available commercial cultivars of this type and distinguish ‘POULgo003’ 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 during winter of 1994 and conducted evaluations on the resulting seedlings in a controlled environment in Fredensborg, Denmark.
‘POULgo003’ was selected in the spring of 1995 by the inventors as a single plant from the progeny of the aforementioned hybridization.
Asexual reproduction of ‘POULgo003’ by traditional budding and rooted cuttings was first done by L. Pernille and Mogens N. Olesen in their nursery in Fredensborg, Denmark in July 1995. This initial and other subsequent asexual propagations conducted in controlled environments have demonstrated that the characteristics of ‘POULgo003’ 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 variety rose ‘POULgo003’.
Specifically illustrated in SHEET 1 is a plant of ‘POULgo003’ growing in a 20-cm hanging basket.
DETAILED DESCRIPTION OF THE VARIETY
The following is a description of ‘POULgo003’, as observed in its growth in Jackson County, Oreg., on plants aged 18 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 ‘POULria’, a rose variety from the same inventors described and illustrated in U.S. Plant Patent application Ser. No. 09/274,686 and dated Mar. 24, 1999 are compared to ‘POULgo003’ in Chart 1.
