Hi everyone. I haven't been on the forum in a few years.
It's a great site.
Anyway this succulent is about 18" tall now and has just one main stem.
Can anyone id this for me.
Most likely Aloe ferox or Aloe marlothii, you will know for sure when it flowers.
Thanks for your reply. Here is a link I found with great photo's.
