You knew you could eat that mayhaw, you could eat muscadines. The April performances are scheduled to coincide with the National Mayhaw Festival. The principal species are "C. aestivalis", the eastern mayhaw, and "C. opaca", the western mayhaw. A post office called Mayhaw was established in 1888, and remained in operation until 1907. For example, Colquitt, Georgia, holds a mayhaw festival in April. El Dorado, Arkansas; Marion, Louisiana; and Starks, Louisiana, all celebrate a mayhaw festival each May. Mayhaw is an unincorporated community in Miller County, in the U.S. state of Georgia.
