Beefy, I cultivated some swamp sunflowers a few years ago and planted them along a split rail fence leading up the driveway to my Mother's house. After a couple of years I got tired of having to clean up the mess after they bloomed(they'd grow to eight ft tall and require hedge trimmers or a chainsaw to cut down) and I annihilated them with some roundup. They're nice out in the wild though.
Duke, you'll have to clue me on the deep meaning. I'm drawing a blank. PM if you wish.
