unexpected but surely most welcome

Except for lithops I only own two other succulents: a couple of Sempervivum that are very dear to me and these two tiny Titanopsis plants (probably calcarea). I'm not even sure the latter get the care they need, I just handle them like lithops. Still, looks like they are doing quite well - there are flower buds coming up :)
Very slowly though.. I'm not at home for the holidays and probably won't see the flowers.
Thanks for your comment
