ABSTRACT:

SUMMARY OF THE INVENTION
The present discovery constitutes a new and distinct variety of a Hybrid Tea rose plant which was discovered in a cultivated area. The mutation resulted from ‘POULrim’, a Hybrid Tea rose hybridized by the same inventors. ‘POULrim’ is described and illustrated in U.S. Plant patent application Ser. No. 09/277,236, dated Mar. 26, 1999. The new rose variety resulted from a naturally occurring mutation of unknown causation on a branch of ‘POULrim’.
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 ‘POULrim’ as well as all other varieties which we are aware of. For example, the new variety has:
1. Abundant, striking orange flowers;
2. Above average disease resistance;
3. Repeat blooming;
4. Vigorous, dark glossy green foliage; and
5. Perfumed rose scent.
This combination of qualities is not present in previously available commercial cultivars of this type and distinguish ‘POULgrena’ from all other varieties of which we are aware. The resulting mutation was selected in spring 1998 and evaluations were conducted on the resulting rose plants in a controlled environment.
Asexual reproduction of ‘POULgrena’ by cuttings was first done by L. Pernille and Mogens N. Olesen in Fredensborg, Denmark, in August, 1998. This initial and other subsequent propagations have demonstrated that the characteristics of ‘POULgrena’ are true to type and are transmitted from one generation to the next.
