RE: native North American aroids
here are the native aroids, as I understand them:
Calla palustris, in the far north.
Symplocarpus foetidus, in the East.
Acorus calamus, in wet spots wherever.
Arisaema triphyllum; some writers divide this in
two or three species; Eastern.
Arisaema dracontium, also Eastern.
Orontium aquaticum, mostly SE
Peltandra virginica, Eastern.
P. sagittaefolia, SE
Lysichitum americanum, the only Western native.
Pistia stratiotes, subtropical FL
A useful category to add might be the naturalized
species, which are capable of colonizing new habitats
and reproducing. Maybe a good hypothetical question
to ask about them is 'would they persist if people
I'd consider chief among these:
Zantedeschia aethiopica, in CA
Colocasia esculenta or close relatives, through
the warm SE and FL
Pinellia ternata, in the NE- NY and NJ and
Anyone seen others going wild? As was said
before, in warm FL the number is legion.
