Luckily, I found one that was ready to flower, and after a couple of days, it rewarded me with 2 flowers! They're like a breath of spring in the middle of winter.
I like them so much that I bought a couple more pots! Hopefully I got different kinds of Titanopsis - I'm not much of an expert in identifying these things. Luckily, these two are also getting ready to bloom!
And while I was at it, I also picked up this Faucaria. The shiny, waxy leaves resemble the jaws of a mammal and while those spines look dangerous, they are actually quite soft.
I think my work colleague has also been infected by the cactaholic bug because he also bought some for himself. He has an opuntia and frithia (which I already have), but he also bought a couple more which I would have wanted myself!
Echinocereus rigidissimus v rubsispina
All these are in our office, and my colleague would occasionally just stand by the window sill, lean over and stare at our mini garden. He would comment at how dry the soil looks (we watered these thoroughly only three days prior) and I would adamantly forbid him to water!
