Rose plant Jacship

Abstract

A shrub class rose plant having upright, vigorous, dense growth habit, dark green, glossy, disease-resistant foliage, heavy production of small pink flowers and ease of production from hardwood or softwood cuttings.

Description

The present invention relates to a new and distinct variety of rose plant of the shrub class which was originated by me by crossing the variety Zorina, U.S. Plant Pat. No. 2,321, with the variety Heidi, U.S. Plant Pat. No. 4,355.

The primary objective of this breeding was to produce a new rose variety having the disease-resistant glossy foliage and upright habit of Zorina combined with the small pink flowers and dense growth habit of Heidi. The 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. Upright, vigorous dense growth habit.

2. Dark green, glossy, disease-resistant foliage.

3. Heavy production of small pink flowers.

4. Ease of production from hardwood or softwood cuttings.

Asexual reproduction of this new variety by softwood and hardwood 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 description using terminology in accordance with The Royal Horticultural Society (London) Colour Chart, except where ordinary dictionary significance of color is indicated.
