I live on a tidal river flowing into the Chesapeake. A neighbor about
1/2 mile downriver has a huge clump of pseudacorus growing on the bank.
It has been there for over 25 years. I have explored five miles down
river by canoe and have never seen pseudacorus in the wild there--just
the nice pale blue of I. virgnica or I. versicolor. From the way that
Louisianas behave in my bog garden, I would be more concerned with
letting them loose.
