Abstract
This invention relates to a new and distinct variety of New Guinea Impatiens plant known by the cultivar name Aztec, and discovered by me in commercial greenhouses in Fremont, Calif. Aztec is closest in characteristics to existing Mikkel Red Coat but is particularly characterized by a distinctive clean-cut variegation; excellent breaking action; a dark yet bright red flower with a white eye, usually ringed with a bluish tint; flowers well with good duration; and makes a very good basket plant and productive stock plant.
