Working on a wetland mitigation site last week, I found three patches and two seedlings of Arum italicum. My question to the PBS members in temperate climates is this:  How invasive is this species? It's listed as invasive in the state of Oregon, which is 25 miles to the south, and it's in a natural area that is supposed to be left alone. I suspect it needs to come out, though that may be difficult, given the likelihood of deeply rooted corms.
