Re: Invasive aroids?

Arum italicum is an invasive in coastal California. I have read a few times that Gonatopus boivini is invasive in the southeastern  US.

Ahhhh...great...thanks all...I took a look at Pinellia, and it is indeed a hard to get rid of invasive here in the northeast.

Cannot agree loudly enough about the Pinellia, the fruit is barely noticeable but I now have it all over my yard and it is difficult to get back in bounds once escaped. Around here (Nashville, middle Tennessee) Arum italicum could probably become invasive, but the leaves are obvious enough that it can be pulled or dug and shared with a warning. But my experience with the Pinnellia spp. tells me to refuse to share this one most seriously. Never have tried Gonatopus outside – would be surprised to find it seed hardy this far north, but it might be – don’t think I’ll test it out. Good Growing!

I'm wondering whether there are any aroids that are considered invasive? I know some aquatics can be (e.g. Pistia stratiotes), but what about any land-based ones?
