Impatiens plant

Abstract

This invention relates to a new and distinct variety of New Guinea Impatiens plant known by the cultivar name Shoshoni, and discovered by me in commercial greenhouses in Fremont, Calif. Shoshoni is closest in characteristics to Red Magic, but is particularly characterized by its orange flowers; color breaks to a very light orange; a less succulent growth; and very floriferous as is Red Magic with a similar dark foliage.

Description

BACKGROUND OF THE INVENTION

The present new variety (seedling) was discovered by me in a commercial greenhouse in Fremont, Calif. as a result of the cross pollination of the pistil parent 76-13-1 (Maya) U.S. Plant Pat. No. 4,258, granted June 6, 1978 and the unpatented pollen parent 76-58-2.

Asexual reproduction of my new cultivar by terminal or stem cuttings grown in pots in a plastic (polyethylene) greenhouse in Fremont, Calif., under normal environmental conditions show that the characteristics described come true to form and are established and transmitted through succeeding propagations.

Color readings were taken during daylight hours in full sun, and all colors are based on the Royal Horticultural Society Colour Chart.

BRIEF SUMMARY

Shoshoni is closest in characteristics to Red Magic. The following outstanding characteristics of Shoshoni distinguish it from Red Magic:

1. Floriferousness equals or surpasses Red Magic.

2. Flower color is orange with very light orange color breaks. Two color breaks occur; a darker one 40D, seen only occasionally, and a lighter one 49D which is the common color break that occurs approximately 2% of the time, i.e. approximately 2% of the blossoms will show the lighter color break.

3. Shoshoni is less succulent.

4. Foliage is not as large or as dark as RED MAGIC.

DESCRIPTION OF THE PHOTOGRAPH

The accompanying colored photograph of the entire plant illustrates the overall appearance of the cultivar Shoshoni, showing the colors as true as reasonably possible for this type of colored reproduction. Under high light the foliage darkens and the flower lightens a little. Supplemental photographs B and C show the lighter color break that is the commonly occurring color break. Photographs B and C (photograph B is a close up of photograph C) depict two typical blossoms that show the orange flecked color break as it normally occurs, and a third blossom whose petals are composed of approximately 40% of the orange flecked color break, which only occurs rarely, but is a good illustration of the color of the breaks. Background color of the flecks is light orange fading into white.
