I purchased this succulent back in December just before we had freezing temps and rain (Southern California). But over time this Euphorbia has had its stalks turn shades of purple in color. Then the stalks become brittle. I feel confident it's a Euphorbia because of the sap which is present until the stalks dry out. It was purchased in a large 20 gallon pot from a nursery in Piru. After the freeze it was moved closer to the house in a sunnier spot. With no improvement I thought perhaps it was receiving too much direct sunlight. I removed the healthier half of the stalks of the pot from one root ball and repotted into a smaller but accommodating pot. It still looks distressed in the new pot.
So my first question is what is it (see picture)? I thought it was Euphorbia Antisyphylitica or Candelilla. No one else thinks so but they can't tell me what it is either. Either way, I'm more concerned about what's wrong with it and what I can do to keep from losing it.
My first impression is pedilanthus macrocarpus. but it appears to have large leaves still attached to it, so its got me stumped.
pedilanthus macrocarpus does not have such large leaves.
Perhaps some other species of pedilanthus... like P. bracteatus?
I'm going to be reckless and throw Ceropegia haygarthii into the mix. Ceropegia dichotoma was a thought too, but the leaves are way off. It's got me stumped too!

Happy growing!
There is always one more glochid. Somewhere. My C&S blog

My guess is pedilanthus too....bracteatus with those leaves sounds right.
