I am not very familiar with various types of plants, but I would like to have a plant or two in the classroom for the cozy aspect and since it can help you stay healthier during the flu season. My classroom does not have a ton of light, and I can't guarantee it will be in constant sun. I would also like something that is pretty hardy and won't die on me easily if it goes a day or two without watering. Any ideas? What do you use in your room?
