Mystery Plant Discovered!

Question

#BarbertonSenecio Hey everyone! I was gifted this mystery plant almost two years ago and never knew what it was until I found this app! However I am not seeing any that are as large as mine when I look up images… Should I trim it down/split it? Or is it okay to just leave as it is and let him keep growing?! Thanks!!

Also… It has never blossomed with the pretty yellow flowers I have been seeing….
