We have lots of bees and bee keepers here in Florida. Got to have them for the citrus groves they ship in bees from all over as well to get the job done. Find the local beeman and plunk down your money for a gallon or two of his finest. The bee people can tell by the color and taste the predominate flower the bees were harvesting but it does get a little mixed. The bees do not realize you only want them to go to the orange trees and not the weeds in the field.
Orange grove owners used to not spray their groves to kill the weeds. One of the dominant weeds in sand and in many groves in Fl is an aster often called Spanish needle. It makes a great honey. I look for areas around orange groves that are not cleared of these flowers so that after the orange bloom they have something else close to feed on.
