I saw this on a tiktok video and would love to know if anyone can figure out where this is at. Google lens isn't helping.

How do I cut this down a foot without killing it?

This is literally my pride and joy. Unfortunately I have to cut this down about a ft to fit in a new house. How can I do this without kill it and how to I propagated the cuttings?

Thank you!
