Lithops, that one died in my care. I thought this one would be easier since I do grow more succulents and drought tolerant plants, so I am used to doing longer watering intervals. I tried twice, just always ending up killing it during/after overwintering stage. It really taught me to be careful with the temperature tolerances and watering frequency. I think my timing to water it is always my mistake.
I also fail with Croton, maybe too dry here. One of these days I will see if I will try it again. I like leaves with different colors and variegations.
Speaking of Phal orchids, I have killed my fair share too, but finally understood how it wants more air at root level, and seeing it always manages to have escapee roots in the container, just wants to wander around. So I have learned to use a different media..hygrolon baggies with lava rock inside, or just chunky lava rock. But I still use the traditional bark media in some, in time will move it to those other media, saves me from root issues.
