Loosetrife will grow in not so wet areas, and it is still sold in some areas as a garden plant.

There is a voluntary green house/propagator ban around here, but I don't know if it's every where. I think some states have it on the noxious weed list, which makes it illegal to propagate, and I think it also requires you take reasonable efforts to remove it fromm your land.

Everyone loves purple loosetrife in my deparment. heh. It gives us all jobs and stuff.
