Impatiens plant--Seneca

Abstract

This invention relates to a new and distinct variety of New Guinea Impatiens plant, known by the cultivar name SENECA, and discovered by me in commercial greenhouses in Fremont, Calif. SENECA is closest in characteristics to U.S.D.A. ARABESQUE but is particularly characterized by its spreading, yet stiff growth; more open growth habit; its dark variegated foliage; its smaller, yet darker candy-striping on white flowers; and its greater flower numbers.

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 76-13-1 (MAYA) U. S. Plant Pat. No. 4,258 and the unpatented pollen parent 75-1.

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

SENECA is closest in characteristics to U.S.D.A. ARABESQUE. The following outstanding characteristics of SENECA distinguish it from U.S.D.A. ARABESQUE:

1. Its spreading, yet stiff growth;

2. Its open growth habit;

3. Its dark, variegated foliage;

4. Its smaller, yet darker candy striping on a white flower; and

5. More floriferous than ARABESQUE.

DESCRIPTION OF THE PHOTOGRAPH

The accompanying colored photograph illustrates the overall appearance of the cultivar SENECA showing the colors as true as reasonably possible for this type of colored reproduction. Under high light the flower color lightens and variegation widens. Most plants give an upright tree form without a pinch, however, the plant in this photograph has a weak lead. The inset photograph illustrates the distinguishing foliage variegation.
