Impatiens plant

Abstract

This invention relates to a new and distinct variety of New Guinea Impatiens plant known by the cultivar name Pawnee, and discovered by me in commercial greenhouses in Fremont, Calif. Pawnee is closest in characteristics to patented plant Azetc (U.S. Plant Pat. No. 4,193; a dark yet bright red flower with a white eye) except for color. Its best description would be to call it an orange flowering Aztec with distinctive yellow-green leaf variegation. The outstanding characteristics of Pawnee are its many orange flowers, its distinct yellow-green variegation, its spreading growth habit, and its excellent breaking action, making a good basket plant.

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 patented pistil parent 76-22-1 (Chickasaw) U.S. Plant Pat. No. 4,260 and the patented pollen parent 76-10-2 (Aztec) U.S. Plant Pat. No. 4,193.

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

Pawnee is best described as an orange flowering Aztec with distinct yellow-green leaf variegation. The following are outstanding characteristics of Pawnee:

1. Many orange flowers;

2. A distinctive yellow-green variegated foliage;

3. A spreading growth habit;

4. Excellent breaking action; and

5. Flowers tend to cup more than with Aztec.

DESCRIPTION OF THE PHOTOGRAPH

The accompanying colored photograph illustrates the overall appearance of the cultivar Pawnee, showing a flower color that has more red than usual. Under high light the flower color goes from a red-orange to orange. The inset photograph taken in January 1979, shows the color of the flower as true as reasonably possible for this type of colored reproduction.
