Goldenrod and asters are both peaking in N/W Wisconsin, but as said there are several species scattered around the Country. In our region it 'usually' puts out flowers for as long as 3 months and is the last flow (last chance) before winter. In past years my bees ignored goldenrod for the first few weeks, likely due to other avilabile forage, but not this year. They began hitting it as soon as it began flowering. This year has been exceptional.
As I understand it "Not all Goldenrod species result in stinky honey."
All of my hive entrances are currently tinted yellow 8-)
