Abstract

A miniature rose variety having a low, well branched, spreading plant; small foliage; abundant blooms in clusters; and deep red color.

Description

This present invention relates to a new and distinct variety of rose plant of the miniature class which was originated by me by crossing two unnamed varieties.

The primary objective of this breeding was to produce a new rose variety of dense habit, clean foliage, and abundant red blooms. This objective was substantially achieved along with other desirable improvements as evidenced by the following unique combination of characteristics which are outstanding in the new variety and which distinguish it from its parents, as well as from all other varieties of which I am aware:

1. A low, well branched, spreading plant.

2. Small, clean foliage.

3. Abundant blooms in clusters.

4. Deep red color which fades very little.

Asexual reproduction of this new variety by cuttings, as performed at Wasco, Calif., 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 my new rose cultivar with color in terminology in accordance with The Royal Horticultural Society Colour Chart except where ordinary dictionary significance of color is indicated.
