I propagated this plant from a leaf back in 2020!

I'm pretty sure this is a Graptoveria 'Opalina' (according to Planta). I started propagating different succulent leaves back in 2019/2020, and this was my most successful propagation! So this plant is about 5 years old :)

Unfortunately I don't have a picture of when it was a baby succulent in 2020, but these pictures are from Jan 2025 and Aug 2022.
