Polyantha rose plant named `Spevu`

Abstract

A polyantha rose variety producing dark pink flowers.

Description

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct polyantha variety which was discovered by me as a sport in a controlled planting of the variety `The Fairy` in Boskoop, Netherlands. The varietal denomination of this new rose is `Spevu`.

SUMMARY OF THE INVENTION

Among the novel characteristics possessed by this new variety which distinguish it from its parent and all other varieties of which I am aware are its attractive dark pink flowers borne on a low growing plant.

Asexual reproduction by budding of the new variety as performed in Watsonville, Calif., shows that the foregoing and other distinguishing characteristics come true to form and are established and transmitted through succeeding propagations. Other known forms of asexual reproduction for roses may be also employed.

Comparison With Parent

The new variety produces dark pink flowers in contrast to light pink flowers of `The Fairy`.

BRIEF DESCRIPTION OF ILLUSTRATION

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