I have 2 plants in my viv. My snakes absolutely LOVE them. I have an easter cactus and a small rubber plant. Both do just fine in my viv. Try to go for non prickly (obviously non poisonous) plants that dont require special environments. Go for an indoor plant that doesnt need alot of sunshine, and doesnt have to be watered excessively ( made that mistake...plant goes mouldy with humidity). Also try not to go for flowery plants (I know my cactus flowers but only once a year!). If you stick to rubber type plants and non spiney cacti you should be ok. Also Im thinking of planting long grasses...could be interesting!
