Ah, such a cheery yellow graces the month of September.  Alas, ragweed flowers out of sight at the same time, giving goldenrod a bad rep among some people with hay fever.  While ragweed sheds pollen to the whims of the wind, goldenrod holds pollen that will be picked up and transported by insect pollinators.  You’re not likely to inhale any goldenrod pollen unless a bee crawls up your nose.
