More Bloomin' Cactus: Parodia Uebelmanniana

Here's a lovely cactus with origins in the uplands of Argentina. I don't see this one for sale often here, and I've grown this one outdoors for several years now. First, the buds....

And then, the bloom!

For me, growing Parodia indoors or outdoors has been a real dilemma. Indoors, their water intake is carefully controlled, so they stay nice and dry most of the time. But they really need outdoor sunshine. They never bloomed indoors. Outdoors, I worry that they are going to rot with the summer rains, but so far, it's a better environment for them. I made sure the soil in their patch was augmented with lots of perlite, so any monsoon-type rains would drain away from the roots quickly and  prevent rot. I don't fertlize them often at all, maybe just twice a year. So far, so good....
