Hi Michael,
I have heard and read varied opinions about this plant? I don't use this plant in my enclosures because of this.
There are --hundreds--- of others to choose from
It's a beautiful plant, I have one hanging in my kitchen window of which I grew it from cuttings a friend sent me. -- I keep it out of reach from the cats.

However, I am not 100% sure for our frogs? When in doubt-I leave it out. It was something about the sap if a stem or leaf is broken.

What kind of frog are you planning on housing with this plant?

Outside, in wide open spaces is different than a confined enclosure housing a frog that could 'take a bite' or break the stems and branches.

Sorry this does not definitively answer your question....it actually just makes it more confusing. Sorry.
I did a quick search ......I don't see this plant on either BJ's or New England Herp's site.
