Beautiful examples of white spined cacti, Ian. Now you just have to cope with hard task to select one for the entry...
By the way : are there any other succulents with white spines too?

Here is another cactus example

Beautiful plant.
True spines are remodeled leaves, but I would say to not exclude succulents from this month topic - everything that is kind of tipped / pokey and sticking out from the surface of a succulent plant, will be a valid entry for this one- as far as it nice and white, haha.

Nice contorted spines on that old man cactus! Definately would qualify as an entry.

Sounds weird. They seem very tough and tolerant to me. Perhaps I don't have quite your summer heat. They're mountain plants and maybe not fond of constant heat. Also they get a lot of rain in summer and I water mine freely whenever the sun is out. It can also survive outdoors here in summer but seems to grow faster in the greenhouse.

I don´t really know what makes it flower. I do water all my EC early in spring (around Feb. 20th) every year and all of them seem to like that treatment. In winter I keep them at 3-5 °C - same as you I guess.

Mammillaria seem to be good objekts when looking for white spines.
But occasionally there are other genera with white spines too....

I don't know what this is. Probably an Opuntia. Here is my entry.
