I was walking with my 13 year old brother one day and the crop looked like funny corn. My brother had to educate me.
Wildwood Flowers grew wild on the farm
We never knew what they was called
Some said it was a flower
And some said it was a weed
I never gave it much thought...
I remember reading once that the song was actually written about joke on weed, which would fit the flower description better and the halucinagenic effect.
