It is a crassula arborescens I think. I had it in a pot with other succulent. I've cut the top part and plant it and I have a bare stem now.

Why did you chop it’s head of Daniela, it looked fine from here over the pond? The base may well sprout again, hope you let the base of the top part dry out/callous over for maybe a day? Don’t water it until you’re certain it’s rooted btw.

Honestly just wanted a smaller stem but I'm already regretting it. I did let it try for two days before and I didn't water it yet. Thank you :)

The base part should resprout providing it has leaf scars around it...look for a ring like mark circling the stem as this is where new leaves/branches should be forced out. You may find that the top section will callous over and pop off the rest if the stem along the line that the topmost leaf scar has left.

Hello! I wanted to share that I now have a beautiful tiny crassula growing in the stem and the one I've cut is established and thriving. Thank you again for your reassurance two months agoago

That's great, how about photo?

These crassulas - ovatas, arborescense - should have a trunk. JMO, but thicker is the main trunk, better it looks. Let it grow and it should eventually look like a tree. Shaping according to your taste should be done by pruning branches - but am sure it will be a while before you need to do any :)

Sorry I didn't get back to you earlier, but I really had no time. Here's a picture!

And I agree, after researching full growth specimens I'm going to work hard to turn into a tree. Thanks again for your help.
