This 104 page guide is the State of the Genus report in the genus Coleus, an important group of tropical, annual bedding plants and house plants. This 2016 update covers the full array of named, unnamed, and trademarked clones evaluated by the International Coleus Society in their "real world" containerized trial garden. It also covers the last two years of cultivar registrations up to #1551 (added December 2016) with detailed descriptions and very large, high-resolution, digital images. Many cultivars have never been published before and several appear no where else in literature.
