Shrub rose plant named ‘JACsuyel’

Abstract

A shrub rose plant characterized by its vigorous, upright growth with fairly small, healthy, dark green foliage; its large clusters of bright copper yellow flowers and ability to root from softwood and hardwood 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 ‘JACjem’, U.S. Plant Pat. No. 5,001, with an unnamed seeding (unnamed seedling×Golden Showers, U.S. Plant Pat. No. 1,557).

The primary objective of this breeding was to produce a new rose variety having the large flower size and multiple petalled characteristic of the female parent as well as its clustering ability and healthy foliage with the vigorous, tall growth, large clusters of dark gold yellow color flowers and healthy, glossy foliage of the male parent. The 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 I am aware:

1. Fairly small, healthy, dark green foliage;

2. Bright copper yellow flower color;

3. Vigorous, upright growth;

4. Ability to root from softwood and hardwood cuttings; and

5. Flowers with 20 to 25 petals.

‘JACsuyel’ is a tall growing shrub garden rose. It flowers in large clusters and breaks freely below the flowering cluster with new flowering shoots. This insures it is in constant flower during the growing season.

Asexual reproduction of this new variety by cuttings (both softwood and hardwood) and by budding, as performed at Wasco, Calif., shows that the foregoing and all other 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.
