Climbing miniature rose plant named `JACmipcl`

Abstract

A new rose variety of the climbing miniature class having a vigorous, arching habit of growth, small, pink, well-formed flowers; dark green, glossy, small leaves; resistance to rust and mildew; and an ability to have lateral buds break quickly and force new flowering shoots.

Description

The present invention relates to a new and distinct variety of rose plant of the climbing miniature class which was originated by me by crossing the variety JACship, U.S. Plant Pat. No. 7,948, with the an unnamed seedling (not patented).

The primary objective of this breeding was to produce a new rose variety having the attractive flower form and vigor of the female combined with the long arching canes, disease resistance and ability to have lateral buds break quickly into new flowering stems of the unnamed red flowered male seedling. 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. Vigorous, arching growth habit.

2. Attractive, well-formed small pink buds produced in clusters.

3. Ability to have lateral buds break and form flowering shoots.

4. Resistant to both rose rust and powdery mildew.

5. Small, dark green, glossy foliage.

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 illustration shows typical specimens of the vegetative growth and flowers of this new variety in different stages of development, depicted in color as nearly ture 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.
