Re: [Aroid-l] Invasive aroids?

From: a sunjian <asjbiotek at gmail.com> on 2018.08.15 at 14:41:03(23986) Whether or not a species becomes invasive definitely depends on the environment and climate (and especially the temperatures as you mentioned below) Outside the Araceae, I know that cogongrass (Impereta cylindrica) is extremely invasive in subtropical and tropical regions around the world, but there is a variety here in the northeast USA that is valued as an ornamental called Japanese Blood Grass: http://plantinfo.co.za/wp-content/uploads/2015/11/Imperata-cylindrica-%E2%80%98Re.jpg Unfortunately, it's the same species, and it has been shown that the variety will revert back to the all-green form and become invasive when grown in an environment more conducive to its tropical nature.

So far, our winters, and below zero F ° seem to be holding off some, but not all of these submerged or emerged plants, but that could change over time.

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 _______________________________________________ Aroid-L mailing list Aroid-L@www.gizmoworks.com http://www.gizmoworks.com/mailman/listinfo/aroid-l --000000000000e65df305737a5049-- --==============65495551525690258==
