I'm in southern Pinellas county and the flows are as follows(for me anyways):
February: Oak (if in strong enough concentration)
March-April: Sweet clover
May-July: Palms and Palmettos (Palm started two weeks ago and palmetto is just opening up this week)/Coral Vine/Mangrove (red)
June-July: Mangrove (mostly Black mangrove but, Red will produce a little)
August-September: Brazilian Pepper (has a sligtly green color)
November-December: very few plants but minor flow will mostly come from "Spanish Needle"
The strong flows of the year will come from Citrus (if near by) Mangrove (if near by), Palmetto (if near by) and Brazilian Pepper. Of all of these, Brazilian Pepper is the most reliable.
Oak honey will have a dark, amber color.
Sweet clover will have a color much like that on the grocery shelves.
Palm and Palmetto is slightly lighter than Sweet clover but, is extreamly "runney" and lacks the viscocity of other honeys.
Spanish needle never really creates any honey but, provides nectar and pollen for the "day to day" existance of the colony. There's probably another 30 plants in Florida that produce the flows (depending on where you are) and, if you like, I have notes from a presentation Laurance Cutts did a few months ago that I could e-mail you.
