Posinous Plants?

I've seen the list of what is ok and what's not for cats. But I want to ask and double check with anyone here.

Does anyone know if these are or are not posionous for cats.

Alternanthera (Purple Knight)
Begonias

Thanks!

Heres a list of plants poisonous to cats:

Thank you for posting that link! I have a peace plant in my bedroom that the cats love to nibble on. Now I know to keep them away from it. At least no one's gotten sick from the nibbles as I've lured them away with a healthy supply of cat grass.

No problem! :)
