Abstract

A miniature rose easily propagated by softwood or hardwood cuttings; having dark green, glossy, disease-resistant foliage; and constant display of bright, deep pink flowers during the growing season.

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 DICmagic, with the variety of DICmerlin.

An objection of this breeding was to obtain a compact growing variety with a high yield of small flowers and foliage.

This new variety evidences these characteristics and 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. Dark green, glossy, disease-resistant foliage;

2. Can be easily propagated from hardwood or softwood cuttings;

3. Has very bright, deep pink flowers; and

4. Blooms constantly and profusely throughout the growing season.

Asexual reproduction of this new variety by softwood cuttings, as performed at Wasco, Calif., and Newtownards, County Down, Northern Ireland, 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 descriptions using terminology in accordance with The Royal Horticultural Society (London) Colour Chart, except where ordinary dictionary significance of color is indicated.
