Impatiens plant -- Navajo
BACKGROUND OF THE INVENTION 
     The present new variety (seedling 76-36-10) was discovered by me in a commercial greenhouse in Fremont, Calif. as a result of the cross pollination of unpatented pistil parent 75-15 and unpatented pollen parent 75-1. 
     Asexual reproduction of my new cultivar by terminal or stem cuttings grown in 6&#34; pots in a plastic (polyethylene) greenhouse in Fremont, Calif. under normal environment 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 
     Navajo is closest in characteristics to USDA Arabesque. 
     The following outstanding characteristics of Navajo distinguish it from USDA Arabesque: 
     1. A rich red-green foliage with a very distinct golden brown to off-yellow variegation under high light, unlike the much lighter variegation of Arabesque. 
     2. A rose-red flower with a light eye and of medium size, unlike the large candy-striped flower of Arabesque. 
     3. Internode is short to medium; a very upright grower with a stiff, thick stem. Arabesque is not as stiff nor as upright. 
     4. Leaves do not cup down as much as Arabesque. 
    
    
     DESCRIPTION OF THE PHOTOGRAPH 
     The accompanying colored photograph illustrates the overall appearance of the cultivar Navajo showing the colors as true as reasonably possible for this type of colored reproduction. However, under high light the flower becomes a rose color and the variegation widens and becomes more distinct. Under low light the flower darkens and the variegation almost disappears; intensity of red leaf pigment decreases. The second photograph illustrates the leaf variability under different environmental conditions.
