Euphorbia ID help

[Southwesternsol]

I was walking around the other day, and I noticed this Euphorbia caught the corner of my eye. I thought it was quite peculiar, since as far as I am aware none of the cactus like Euphorbias are particularly cold hardy.  I'm not real familiar with the genus, so I'm struggling to identify which specific Euphorbia it is. Was wondering if anyone here knew.

Didn't think to snag a picture at the time, but luckily Google Street View just updated a bunch of streets here.

Tough call from that distance.. Can see some resemblance to Euphorbia resinifera  ...What is often called " Moroccan Mound "  but there are other Cacti-like Euphorbs with a similar look / profile. 


If E. resinifera,  it is supposedly hardy to the low 20s ..maybe a tad lower,  if it stays dry..

That's one I considered, but I figured this was a little too erect and tall. But I could see it. If I find myself on that street in the near future, I'll get a better picture.

Took alot longer than I anticipated to get a better photo. Still can't identify what Euphorbia it is, and iNat isn't helping me. I'm usually pretty good at being able to identify plants, but this one has me stumped.

Didn't see anything there. I've also looked through the Genus search on Davesgarden. The closest I can see is E. Canariensis, but that still doesn't quite match. Maybe it's some kind of cultivar. Still definetaly curious about the hardiness, because I'm not aware of any hardy cactus like Euphorbias. We've also had some pretty cold nights already, and it seems to have been unphased, unless they protected in somehow.

I know there's at least a few ( Palm Bob's Article listed more than i was aware of actually )  but agree, not sure just how " hardy " even the hardiest of the cacti - looking types would be..  Hardy to say the mid 20's is one thing,  compared to being able to withstand low 20s / teens ( ..or occasionally lower )

A crossed cultivar could definitely throw things off ID-wise, let alone influence any potential lower end cold tolerance..  You'll have to report back after winter.. Even if someone might have to provide protection through the coldest part of your winters, i'm sure a " fairly tough",  nice looking / clumping Euphorb. like that would catch on up there..

When you first posted the lesser detailed image of this so called hardy Euphorbia, my initial impression what that it was a plastic rendition of a type of Cereus. With this new image, I'm 90% sure my first impression was correct. If you look at the base, you can see how the hollow plastic casts are attached to the base, and it's basal projections. This will be hardy to nearly every weather condition.
