I learned what Dark Green Bulrush sedges looked like the other day. This seems like that to me only the tops are WAY bigger with far more going on. I love the close up shot of the inflorescence. Note the band of dark red on the leaf sheath. These were in the jack pot of an unkempt lot next to the bank in Ellsworth, Maine on July 3.
