Miniature rose plant named POULming

Abstract

A miniature rose plant, a mutation of the variety POULoral, having a distinctive light pink flower color as compared to the coral flower of its parent, while having similar plant habit, foliage and flower production.

Description

The present invention relates to a new and distinct variety of rose plant of the miniature class which was originated by us by selecting a pale pink flower color mutation from the coral flower colored variety POULoral (disclosed in copending application Ser. No. 08/209,844).

The primary objective of this selection was to produce a new rose variety having the same color of foliage, the same plant habit, and the same flower production of POULoral but with a distinctive and novel flower color. This 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 we are aware:

1. Similar plant growth habit, foliage and flower production to POULoral; and

2. Distinctive and novel flower color.

Asexual reproduction of this new variety by softwood cuttings as performed at Wasco and Somis, Calif. and Fredensborg, Denmark, shows that the foregoing characteristics and 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 significance of color is indicated.
