New to this forum and desperately looking for help. I live in Sydney and found this plant on the side of the road towards the end of summer. It was beautiful when I took it home but it hasn't taken long to either. Trying to save it but I'm not sure what to do! It didn't do well outside, in my room or in my bathroom. All which get half sun maybe but nothing direct. I don't know what it's called either, hence my need for y'all's help. Photos included. Really hope it's not too late. Thanks!!!
