I’ve had this cactus for many years, in fact, I’m not even too sure anymore where I got it except I think it was from a classmate in university, in the early mid 90’s when I was at Lakehead University in Thunder Bay. The one I’m currently taking care of was a bud from an older one that was with me for many years, and it finally bloomed, for the first time ever that I’ve seen in 25 years.

I noticed that the flower opened very slowly, and that a couple days later it was still not fully open.

A few days later, it has largely opened and I can see inside. Here is a photo taken yesterday (followed by the closeup)

I will try to post updates in the coming days as the bloom matures and as the other blooms open.
