I suspect there is some variation depending on the clone. I have
two accessions of Pinella ternata, considered one of if not the
weediest of the genus. One, from Jim Waddick, I've grown outdoors
for many years now. It grows so slowly there were years I wasn't
sure it was increasing at all. Definitely not invasive, in my
climate.
The other, acquired later from another source, is very vigorous.
Seeds and bulbils everywhere, it's a real problem and I don't let
it out of the greenhouse or share it. One of my projects for this
year will be at least to get it back in bounds, because currently
I don't dare recycle medium from that part of the greenhouse into
my outdoor beds. I may just go on an eradication campaign.
Arum italicum is borderline here (NW Arkansas). It seeds around
our yard, not rampantly but consistently. Fortunately, as Jonathan
says, it's easy to recognize even when small, and so far I've only
seen it jump into nearby shady areas.
Gonatopus has not survived outdoors here.

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!

Subject: [Aroid-l] Invasive aroids?
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?
