Miniature rose plant named Poultre

Abstract

A miniature rose plant having attractive, light pink flowers; compact growth habit; ease of production from softwood cuttings; excellent keeping ability, and the production of many of the flowers in clusters.

Description

The present invention relates to a new and distinct variety of rose plant of the miniature class which was originated by us by crossing two unnamed seedlings.

The primary objective of this breeding was to produce a new rose variety having a low, compact growth habit suitable to grow from cuttings in a 6 cm pot; an attractive, light pink flower color; good keeping quality as a pot rose; and flower production in clusters. 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 varities of which we are aware:

1. Soft, light pink flower color;

2. Ease of production from softwood cuttings;

3. Excellent keeping quality;

4. Production of flowers in clusters; and

5. Compact growth habit.

Asexual reproduction of this new variety by softwood cuttings are performed at Wasco and Somis, Calif., and Fredensborg, Denmark, shows that the foregoing characteristics adn distinctions 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 our new rose cultivar with color descriptions using terminology in accordance with The Royal Horticultural Society (London) Colour Chart, except where ordinary dictionary signficance of color is indicated.
