Burdock is a common weed of old farms, introduced from Europe and now widespread throughout Michigan.  It's most commonly recognized in the fall by the brown cockleburs, which are 1/2 - 3/4 quarter inch round balls of barbed spikes.  They stick to just about anything, even nylon pants and hairy legs!  It's fun to toss the cockleburs into someone's hair, as long as you know the secret of removal . . . pull the hair from the cocklebur, not the cocklebur from the hair!  Burdock has huge leaves, especially at the base of the plant, somewhat similar to rhubarb.  The plant can reach heights of five feet and have a large branched crown with dozens of cockleburs.
