Abstract

A miniature rose plant characterized by the unique combination of its compact but vigorous, upright habit of growth, its dark green, glossy foliage, its large flower clusters, its dark red-purple fading to lavender flowers, and its ease of propagation from softwood cuttings.

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 the variety SAVawin, U.S. Plant Pat. No. 5,691, with the variety JACsil, U.S. Plant Pat. No. 6,010.

The primary objective of this breeding was to produce a new rose variety having the compact dwarf habit and small flowers of the female parent combined with the glossy foliage, good clustering potential and vigorous growth of the male parent. This 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. Deep red-purple buds that lighten upon opening;

2. Vigorous growth;

3. Small, dark green, glossy foliage;

4. Production of flowers in large sprays;

5. Compact habit of growth; and

6. Ease of propagation from softwood cuttings.

Asexual reproduction of this new variety by softwood cuttings, 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.

The base of each petal has a Greenish-White (1/8 inch by 1/8 inch) half moon at the point of attachment. The major color on the upper side is Red-Purple Group 60A.

Variegations.--None.

Discoloration.--The general tonality at the end of the first day: No change. At the end of the third day: Gradual change from Red-Purple Group 60A to Red-Purple Group 63D as the flower ages.

Fragrance.--Slight.

Petals:

Texture.--Thick.

Claims

I claim:

1. A new and distinct variety of rose plant of the miniature class, substantially as herein shown and described, characterized particularly as to novelty by the unique combination of its compact but vigorous, upright habit of growth, its dark green, glossy foliage, its lower flower clusters, its dark red-purple fading to lavender flowers, and its ease of propatation from softwood cuttings.
