Materials and Methods
Data are being collected on growth stage, plant vigor, plant height, flowering date, number of flowers once every other week starting May 24, 2013. Any diseases, insects, or other abnormalities encountered are being monitored and diagnosed. At the late bud/few flowers open stage, E. purpurea aerial parts were collected, weighed, dried, reweighed, and shipped to Nutrilite for phytochemical analysis in late June, 2013. At the end of the growing season in 2013, roots from the Year 2 plots of each species at each location will be harvested, washed, weighed, dried, reweighed, and sent to Nutrilite for phytochemical analysis. The harvests would have been impossible without the amazing help we received from the crews at the Reidsville and Mills River stations.
