Climber rose plant named `JACpicl`

Abstract

A climber rose plant characterized by the unique combination of its strong, upright then arching habit of growth, its ability to have buds break freely along its arching stems, producing an abundance of bloom, by its dark green, glossy, disease-resistant foliage, and its production of flowers in clusters of 3 to 9.

Description

The present invention relates to a new and distinct variety of rose plant of the climber class which was originated by me by crossing the variety JACship, U.S. Plant Pat. No. 7,948, with the variety INTERlada, U.S. Plant Pat. No. 6,068.

The primary objective of this breeding was to produce a new rose variety having the fully double pink flowers and profuse flowering of the female parent combined with the long arching canes and good disease resistance 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. A strong, vigorous, upright then arching growth habit;

2. Breaks freely along the stem producing continuous bloom;

3. Dark green, glossy, disease-resistant foliage; and

4. Flowers produced in clusters of 3 to 9.

Asexual reproduction of this new variety 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 illustrations show 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.

Sheet 1 shows shows the whole plant growing in the field.

Sheet 2 provides a more detailed view of the vegetative growth and flowers of the new variety.

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.

Claims

1. A new and distinct variety of rose plant of the climber class, substantially as herein shown and described, characterized particularly as to novelty by the unique combination of its strong, upright then arching habit of growth, its ability to have buds break freely along its arching stems, producing an abundance of bloom, by its dark green, glossy, disease-resistant foliage, and its production of flowers in clusters of 3 to 9.
