Interesting observation. These are 2 Hoya plants (succulents), one veriegated, one not. They typically need cacti mix. I've never been able to keep them staying plump and as you can see, the one of the left is dehydrated looking, and not for the lack of under-watering. I repotted the one on the right last week in coir and look at the difference now. Today, the veriegated Hoya goes into coir; the stuff is great!
