Abstract
‘UF0646’ is a new coleus plant distinguished by having excellent red-magenta color in both sunny and shady locations. It appears more rose-red under high light intensities, and has exceptional branching and growth habit, and good sun and heat tolerance. It has desirable characteristics that allow it to retain its leaves in the garden landscape for an extended period of time during the normal growth season compared to most coleus varieties. It is an excellent variety for commercial production due to excellent adventitious rooting characteristics of vegetative propagules (cuttings), and subsequent vigorous growth in greenhouse conditions. ‘UF0646’ has proven to be an excellent performing variety in preliminary outdoor trials across the United States, and should be an excellent choice to add vibrant long lasting annual red color to gardens across the United States, Canada, and Europe.
