Rose plant named ‘POULshrimp’

Abstract

A new miniature rose which has abundant, orange-red 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 CLASSIFICATION

Rosa hybrida.

VARIETY DENOMINATION

‘POULshrimp’.

SUMMARY OF THE INVENTION

The present invention constitutes a new and distinct variety of miniature rose plant which originated from a controlled crossing between ‘POULege’, a rose by the same inventors, described and illustrated in U.S. Plant patent application Ser. No. 09/282,073 dated Mar. 29, 1999; and ‘POULvic’, a rose by the same inventors, described and illustrated in U.S. Plant Pat. No. 8,012 issued on Oct. 27, 1994. The two parents were crossed during the summer of 1990 and the resulting seeds were planted in a controlled environment in Fredensborg, Denmark. The new variety is named ‘POULshrimp’.

The new rose may be distinguished from its seed parent, ‘POULege’, by the following combination of characteristics:

1. ‘POULshrimp’ has bright orange-red blooms, whereas the ‘POULege’ has salmon-orange blooms.

2. ‘POULshrimp’ is a miniature garden rose, whereas ‘POULege’ is a floribunda rose.

3. ‘POULshrimp’ exhibits more compact and even and growth than ‘POULege’.

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

1. ‘POULshrimp’ has bright orange-red blooms, whereas ‘POULvic’ has red blooms.

2. ‘POULshrimp’ exhibits less flowers per stem when compared to ‘POULvic’.

3. ‘POULshrimp’ is a larger plant in height and width than ‘POULvic’.

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;

3. Disease resistance.

This combination of qualities is not present in previously available commercial cultivars of this type and distinguish ‘POULshrimp’ 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 1990 and conducted evaluations on the resulting seedlings in a controlled environment in Fredensborg, Denmark.

‘POULshrimp’ was selected in the spring of 1991 by the inventors as a single plant from the progeny of the aforementioned hybridization.

Asexual reproduction of ‘POULshrimp’ by traditional budding and rooted cuttings was first done by L. Pernille and Mogens N. Olesen in their nursery in Fredensborg, Denmark in summer 1991. This initial and other subsequent asexual propagations conducted in controlled environments have demonstrated that the characteristics of ‘POULshrimp’ 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 ‘POULshrimp’. Specifically illustrated in SHEET 1 include ‘POULshrimp's’ foliage, flower buds, partially opened buds, and numerous open blooms.

DETAILED DESCRIPTION OF THE VARIETY

The following is a description of ‘POULshrimp’, as observed in its Half Moon Bay, Calif. Oregon, on plants aged sixteen weeks. Root development for the observed plant typically takes 8 to 10 weeks. 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 ‘POULrouge’, a rose variety from the same inventors described and illustrated in U.S. Plant Pat. No. 9,687 issued on Nov. 12, 1996 are compared to ‘POULshrimp’ in Chart 1.
