I purchased the seeds of this plant a few years ago which were identified by the seller as "Turnera diffusa" (Damiana). It is a beautiful plant but there is some question about the taxonomy. I do believe it is Turnera diffusa because this is the host plant for the Mexican Fritillary butterfly and my plant was well used by that butterfly and lots of caterpillars have grown up on it. Although it is possible that these butterflies would use any "Turnera" as a host. The images on the internet are all over the place and not reliable. Any ideas? I would like to add it to the database but don't want to classify it incorrectly.
