Miniature rose plant named `JACnikl`

Abstract

A miniature rose plant having pale, cream-pink flower color; 13/4 inch open flowers borne singly and in clusters of three to five; pointed ovoid bud form; long flower life on the plant; and medium, dark green, semi-glossy foliage.

Description

The present invention relates to a new and distinct variety of rose plant of the miniature class which was originated by me by crossing `MORsegold`, U.S. Plant Pat. No. 6,617, with the variety `RUImired`, U.S. Plant Pat. No. 5,770.

The primary objective of this breeding was to produce a new miniature rose variety having pointed ovoid buds borne in small clusters with 11/2 to 2 inch open flowers, long flower life, and suitable for propagation from softwood cuttings and greenhouse production as a miniature pot rose. 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. Pale, cream-pink color;

2. 13/4 inch open flowers, borne singly and in clusters;

3. Pointed ovoid bud form;

4. Ten to twelve day flower life, on the plant; and

5. Medium sized, dark green, semi-glossy foliage.

The plant propagates readily from softwood cuttings and is able to be grown in 4-inch pots in a 13-14 week production cycle or in 6-inch pots in a 16-18 week production cycle, making it very capable of pot rose production culture.

Asexual reproduction of this new variety by cuttings, as performed at 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.
