I didn't reply because I wasn't sure. You could check the safe plant list if you really want to use it. I have pothos, a fern, and a schleffera in mine. Too bad you can't get a pothos, because they go well in anything. Sorry I can't be of more help.
Hey, didn't realize you were in Ontario. Have you tried Home Depot at all? Even Rona sometimes has them.
If you can't find anything I can pack up some small slips and mail them to you Express Post. They should be ok. Plus they grow like crazy so should fill up your enclosure rather quickly. Just let me know!
