Patent Publication Number: US-4410-P

Title: Impatiens plant -- Osage

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 76-2-1 (CREEK) U.S. Plant Pat. No. 4,261 and the unpatented pollen parent 75-34. 
     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 
     OSAGE is closest in characteristics to Longwood&#39;s CAROUSEL. The following outstanding characteristics of OSAGE distinguish it from Longwood&#39;s CAROUSEL: 
     1. OSAGE has a much larger flower; 
     2. Although variegation is similar, OSAGE has a larger leaf; 
     3. OSAGE has longer internodes with a very upright form, making an excellent pot type plant; 
     4. OSAGE flowers more consistently; CAROUSEL can be difficult to get to flower. 
    
    
     DESCRIPTION OF PHOTOGRAPH 
     The accompanying colored photograph illustrates the overall appearance of the cultivar OSAGE, showing a flower color slightly darker than usual. Under high light the flower color goes from a red-orange to orange.
