here in alaska the fireweed is profuse and depending on the year and the rainfall gives a medium to strong flavored honey that is wonderful for eating or mead I like that but am also curious about other flavors. I don't know if it grows in your area and i don't know the latin name but when it blooms this year I'll click a digital and post, it's what most keepers here set their hives on.
In Finland we say it milk horsma. It's latin name is Chamaenérium angustifólium.
Here is pic from alaska and another from Finland.
In Finland it is the most important honey flower, because it grows in every harvested forest.
I have fertilized fireweeds in forest and it's bloming encrease many fold.
