Technical Abstract: Turnera diffusa is a widespread and variable species found throughout tropical America. Commonly known as “damiana,” it has figured extensively in folk medicine. In this article, we promote to the industry the release of a cultivar of T. diffusa with outstanding ornamental qualities selected from a population in Puerto Rico called 'Luisa'. The form has attractive gray-green leaves, compact habit, and flowers for most of the year. It is easily propagated and can be used in the landscape as a ground cover, edging or bedding plant.
