Hi! I have what I believe to be a tradescantia spathacea tricolor...purchased over a year ago in a pot without a label. It didn't grow much until this past April, and hasn't stopped growing! It's now tall and can't stand up on its own, but I'm not sure if it is supposed to be trailing or if I should stake it so as it continues to grow it stays upright. Please help! (Attaching way too many photos so you can helpfully confirm what plant this is in the first place...thank you!!)
