Barb Miller wrote about the possibility of early pollen.  I know that before
I was interested in bees, that I was really unaware that there were some
real early bloomers.  My bees in central Missouri have been collecting
pollen for a couple of weeks when we have warm weather.  Skunk cabbage and
willows bloom early.  I saw in the woods a couple of days ago, aromic sumac
blooming, the maples are on the verge of blooming, there is a blue weed that
blooms early called henbit, I think.  I have seen some patches of it in
fields as I drove along the road.  And of course it does not take very long
for dandelions to bloom.  There may be some early bloomers in the woods
outside of your place.  It's amazing how much activity is going on in the
plant world and we are totally unaware until we keep bees.
