Miniature rose plant named ‘Poulpar043’

Abstract

A new miniature rose plant that has abundant, red flowers and attractive foliage. The variety successfully propagates from softwood cuttings and is suitable for year-round production in commercial glasshouses. 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: ‘Poulpar043’.

SUMMARY OF THE INVENTION

The present discovery constitutes a new and distinct variety of miniature rose plant which was discovered in a cultivated area. The new rose variety resulted from a naturally occurring mutation of unknown causation on a branch of ‘Poulpar029’, U.S. Plant Pat. No. 16,148. The resulting mutation was selected and evaluations were conducted on the resulting rose plants in a controlled environment.

The rose plant of the present discovery has a unique combination of characteristics which are outstanding in the new variety and which distinguish it from the original rose ‘Poulpar029’ as well as all other varieties which we are aware of. For example, ‘Poulpar029’ has a general flower color of Red Group 53A. ‘Poulpar043’ has a general flower color of Red Group 40A. ‘Poulpar043’ also has flowers which are slightly larger than ‘Poulpar029.’

The criteria used to evaluate the claimed plant were selected in order to introduce a distinct variety for garden use with unique qualities, such as:

• • 1. Uniform and abundant red flowers;
  • 2. Vigorous, but very compact growth when propagated both as a budded rose and on its own roots;
  • 3. Exceptional disease resistance; and
  • 4. Long lasting flowers.

This combination of qualities is not present in previously available commercial cultivars of this type, known to the inventor, and distinguish ‘Poulpar043’ from all other varieties of which we are aware.

Asexual reproduction of ‘Poulpar043’ by vegetative cuttings was first done by Mogens N. Olesen in Fredensborg, Denmark, in July of 2001. This initial and other subsequent propagations have demonstrated that the characteristics of ‘Poulpar043’ are stable and reproduced true to type in successive generations of asexual reproduction.
