I came across some photos of this houseplant which I grew several years ago. Unfortunately none of my photos are named and I can't remember what it is.

It had clusters of small white flowers.

Crassula rosularis. Dont ask how, I had a hunch.

Really nice, such a pretty Crassula! Here's our database for Crassula orbicularis var. rosularis. According to the Catalogue of Life, C. rosularis is a synonym.

Excellent, knew I could count on you. That's definitely it.
