Keith Zary hybridized Gemini by combining Anne Morrow Lindberg and New Year. Bear Creek is the introducer. Rich dark green foliage accents the deep red velvety blooms. Shrubs may reach 3 t 4 feet in height and width. The Kordes Company hybridized this bold variety with a combination of Bad Fussing and Ingrid Bergman.
Foliage is glossy, with just a tinge of purple.
Knock Out appears to be totally blackspot resistant.
