Please give all the information you can find about female cultivars of M. cerifera.  It is abundantly easy here to find wax myrtles that have few or no berries, thereby nullifying their value as a food supply for many birds.  Since it's likely that not all cultivars will be available to me (Columbia, SC) through nurseries, I would appreciate as large a selection of female cultivars as possible.  Males do not seem to be as much of a problem to find.

Thanks very much.
