Yeah, when I threw in euphorbia, I was being smart-ass and ignoring the immense variability of the members of the family. (Genus? Whatever.) My bad.
Sorry, I don’t know offhand of any that do well in low light – mine are all in south-facing windows that get a lot of light. In general, succulents (including both cacti and euphorbia) tend to be drought-tolerant, sunloving plants. The non-succulent euphoribia are a different kettle of fish.
It might be worth starting a new thread asking specifically – I’m guessing that those who would have better advice for you might not be reading this thread.
I’ll give you this advice in advance: When you are dealing with cholla, don’t even try to grab it and pull it off. You will ignore this advice exactly one time, then you will remember to get a comb to pull the cholla out of your hide. Remember, cholla has barbs so expect it to put up a bit of a fight.
I just did a 24 hour mountain bike race just north of Tucson, though huge fields of prickly pear and cholla. Nothing like riding inches away from a six foot tall cholla at 3 in the morning to remind you to pay attention.
While I have usually seen the teddy bear and jumping cholla in the Sonoran Desert, there is another variety that does well at cold and high elevations. I’ve seen it near Santa Fe. I’ll see if I can find photos of this type.
For many years I’ve been growing indoors Euphorbia leuconeura from Madagascar. Very easy to grow and propagate. Height about 10 ". It has the peculiarity to propulse its seeds (up to 2 feet I think).
This year I put them in full sun and they are just “stagnating”, blooming but not producing leaves.
Too late now, as the OP has already solved the problem, but another alternative to duct tape / wood glue is a home waxing kit. One of those “true ER stories” on Discovery Health had the ER docs using exactly this to de-cactusize a child.
Slight hijack for dog owners: NEVER let a non-cactus savvy dog run free in the vicinity of chollas. I have witnessed two separate incidents at Joshua Tree National Park’s “Cholla Garden” nature trail where tourists let their unleashed pet out, with tragic results.
I have grown cholla in Orem, Utah. It does get cold here, but not very wet (total annual precipitaion similar to the Sonoran Desert). Pretty much a plant it and ignore it operation.
