I'm constantly amazed ....

There are some Cacti that generate more than one flower per areole, can’t remember the names offhand, I think there is a large cereoid that does it, and some epiphytic cacti do it too

Weingartia regularly do so

Slightly off topic, but I swear for Olympus TG-6 for its macro capabilities. Zoom up to x4, focusing on objects on the camera lens (I am not joking, had it focus on the dust covering the lens once or twice...), built in focus bracketing and stacking...

I have one of these too. The focus stacking is really impressive. While it says to use a tripod for the best results, it does an excellent job handheld, too. It was recommended to me by a bryologist friend who uses it for mosses, which are typically much smaller than cacti...

Thanks for that information. I'll be watching my test subject ....

There's a Swedish photographer who I follow on YouTube who has recently gone over to the new OM system. He hand holds for stacking of insects. That's double possible movements ... subject AND photographer.

Question.
If the offsets are eventually removed ... will others form at the same sites. Or is it once and once only?

I was potting a couple of small Echinopsis on this afternoon and taking the opportunity to remove some small offsets forming all over one particular cultivar and wondered if some of the occasions we see offsets coming back at the same areole is when an offset has left a small amount of tissue behind that can grow again?

That ... has given me an idea
