I got these guys from my parents a few months ago. They didn't know what they were and neither do I so I'm coming here for help. I have no knowledge on plants but I can tell you what the pictures maybe can't. -The leaves have wax look to them. -The poles get more green the closer to the top they are. -The leaves all curl inward, away from the sky. -The leaves have little spines on their edges. Thank you so much for your help :)
