Hi! I have these really cute jars that I want to put plants in but I don't know what could go in them. I already have some ivy in a couple jars so I would prefer something new. They don't have any drainage holes but I don't even know if they would work with soil or if I should just focus on plants that can grow in water. Also, I am a beginner level when it comes to gardening so I'm looking for plants that are little hardier and not so easy to kill. Thanks!
