Thank you so much. This info is all very helpful. As a collector, albeit a small time collector, I want to add a Thai Soco to my group and I was confused that many Thai arabicum were visually (in pictures) to be nearly identical to soco.
When you add in that some articles dispute that soco is a true cross or just a mutation. You can see my confusion.
I used to see so many adeniums at the weekend market in Bangkok. Unfortunately, I was not interested in adeniums at that time so I did not pay close attention. Opportunity lost, wish I could go back and do again
