Excellent photos! They have made me want to grow some little cacti myself. I tried in the past, in my youth. I didn't have the patience and I see now that patience is needed. Now I think I'm ready but I have a big problem, my wife doesn't like cacti.
Mammillaria Bombycina, wow! What a beauty, really photogenic. I'll try to get one at least.
Thanks for showing me their beauty.
You should try! They do not require much care and can be left alone for weeks (especially in winter, when they rest).
Mammillaria Bombycina - it is a common one. I got mine in Lidl for around 1-2 euro. They often have nice cacti. Start from one and see if your wife changes her mind ;)
I will try it. Thanks for the advice.
