edible houseplants for mice?

hi! I have about 10 Egyptian spineys, and I am trying to make a really nice
place for them in my 55 gallon critter cage....are there any houseplants
that don't grow too large that I can put in with them that are also
non-poisonous? Thanks in advance....

PS I realize that I will have to replace them all the time, but this will be
in my living room, and I want it to look nice..

Thanks again!!!!
