USPP10962P - Shrub rose plant named `JACina` - Google Patents

Abstract

A continuously flowering shrub rose plant with five petaled flowers of deep pink color, the plant having a uniform, rounded growth habit, a resistance to black spot, and tolerance of powdery mildew and rust.

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 China Doll, U.S. Plant Pat. No. 678, with the variety MORchari, U.S. Plant Pat. No. 5,975.

The primary objective of this breeding was to produce a new rose variety having high flower production, full compact habit, disease resistance, pink to red in color, and fragrance. 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. Superior continuous bloom;

2. Full, compact, rounded habit of growth;

3. Resistance to blackspot;

4. Tolerance of powdery mildew and rust;

5. Deep pink color;

6. Light, spicy fragrance.

7. A deep pink, five petaled flower, its parent `China Doll` having a slightly fragrant, medium pink flower with 20-26 petals, and `MORchari,` a very fragrant, lavender to purple flower of 40 plus petals. JACina's mature plant is 28-30 inches in height whereas China Doll grows to about 18" in height and `MORchari` to between 24-28" in height.

Asexual reproduction of this new variety by cutting propagation, as performed at Wasco and Somis, 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.
