Miniature rose plant named `Poulhappy`

Abstract

A new rose variety of the miniature class having a compact, well-branched habit, good production of flowers in clusters, attractive red flowers and long shelf life as a potted rose.

Description

The present invention relates to a new and distinct variety of rose plant of the miniature class which was originated by me by crossing the variety POULvic, U.S. Plant Pat. No. 8,012, with an unnamed red flowered seedling, not patented.

The primary objective of this breeding was to produce a new rose variety having the habit of growth, clustering ability and shelf life of POULvic combined with the larger, bright red flowers of the unnamed seedling. The objective was substantially achieved, along with other desirable improvements, as evidenced by the following unique combination of characteristics that are outstanding in the new variety and that distinguish it from its parents, as well as from all other varieties of which I am aware:

1. Compact, well-branched habit.

2. Good production of flowers in clusters.

3. Attractive red flowers.

4. Good post-harvest shelf life as a potted rose.

Asexual reproduction of this new variety by softwood cuttings as performed at Wasco and Somis, Calif., as well as at Fredensborg, Denmark, shows that the foregoing and all other characteristics and distintions come true to form and are established and transmitted through succeeding propagations.

The accompanying illustration shows typical specimens of the vegetative growth and flowers of this new variety in different stages of development, depicted in color as nearly true as it is reasonably possible to make the same in a color illustration of this character.

The following is a detailed description of my new rose cultivar with color descriptions using terminology in accordance with The Royal Horticultural Society (London) Colour Chart, except where ordinary dictionary significance of color is indicated.
