American Green Tree Frog habitat plants question.

[DonLisk]

Spathiphyllum wallisii produces calcium oxalates, which is toxic so I would recommend NOT to use this with your frogs.

Bromelia excellent will be fine to use and is pretty sturdy for your frogs to climb on. Golden Cane Palm should also be fine to use also.
Most Bromeliads, Snake Plant, Pothos, and Creeping Fig work well with tree frogs and once grown in will allow for plenty of frog activity.

Keep away from plants such as umbrella plants since the stems, if broken, contain a toxic sap that will harm your frogs.
Numbing to humans even.

I think it might be in the same category as Pothos, bad for pets to eat but ok to sit on, The Peace Lily (Spathiphyllum spp.). I have no experience with it though.

In addition to the plants Don mentioned, my American Green Treefrog loves the various Peperomia obtusifolia. Nice sized leaves for them and some grow upright to fill a vertical space.
