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.
I like dark honey. I have some from 17 years ago that was the best and has not crystallized. It was from a swamp weed during a very dry summer. The bees worked extra hard that summer due to lack of flowers
