I new something was odd when I saw the link Brettski supplied.
I know the cattails in my locale are not a problem, so what's the deal? Could it be, possibly, be a different species.

Narrowleaf cattail and its meaner cousin, a hybrid between 'gentle giant' broadleaf and 'crazy mofo' narrowleaf, are known to be way more invasive than the common broadleaf that is currently in my neck of the ponds.
Exotic cattails have come for you!
