Down here in FL, if we sell honey labeled as a certain "Pure" floral source it has to be tested by the state to determine if it is as labeled. I'm pretty sure the state just does a pollen count. BTW, we have to pay for this and it's not cheap, although I haven't personally had the lab tests done. We just use a general floral source label such as "Orange Blossum" or "Wildflower."
