Re: [Aroid-l] Invasive aroids?

From: Tom Croat <Thomas.Croat at mobot.org> on 2018.08.15 at 02:31:15(23977) While it is true that if you introduce Pinellia you have it forever. It does invade beds that you don’t till every year but it does not persist in my Canna beds. Where it does come up it forms a nice look all growing to the same height. It does get in to my liriope bed but is easy to pull up every month or so. Tom HTML +More From: aroid-l-bounces@www.gizmoworks.com [mailto:aroid-l-bounces@www.gizmoworks.com] On Behalf Of D.

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? _______________________________________________ Aroid-L mailing list Aroid-L@www.gizmoworks.com http://www.gizmoworks.com/mailman/listinfo/aroid-l _______________________________________________ Aroid-L mailing list Aroid-L@www.gizmoworks.com http://www.gizmoworks.com/mailman/listinfo/aroid-l -- D.
