Re: Invasive aroids?

---

The funny thing is I've always considered aroids to be these unusual tropical plants that actually have to be protected, so it's interesting to see that some species do become invasive.

In fact, Syngonium podophyllum  is also considered an invasive in FL. not just in Malaysia.

http://edis.ifas.ufl.edu/in530

It is classified as a Category I invasive (which is where such heavyweights as cogon grass and kudzu are also placed).

CATEGORY I

Invasive exotics that are altering native plant communities by displacing native species, changing community structures or ecological functions, or hybridizing with natives. This definition does not rely on the economic severity or geographic range of the problem, but on the

documented ecological damage caused.

Here in Malaysia Syngonium podophyllum is pestilential, even invading mature secondary forest. Dieffenbachia not much better.

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!

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?
