Euphorbia mammillaris variegated

[Andrew in Germany]

Just bought a small Euphorbia mammillaris variegated for next to nothing. 3 little things in a pot. Can’t find much info about how big they will get but most websites show pictures of a crawling / clumping plant. I hope that’s the case… anyone got some good pics of this?
Here’s a pic of the little bairn.

And the sun burned version… just talking to myself….
