I picked up this cutie a couple of years ago at Masters, I knew it was from Hamiltons Nursery, but hadn't been able to work out what it was. Had assumed it was a senecio as it stressed to purple (a common feature of that family).
Pretty little thing, quite similar to chalksticks just a little greener, and with a yellow flower rather than a white flower.
Anyway, while staying at the hotel I was chatting with Noelene, and she happened to have this one in her car. Yep there it is! labelled at last.
It's nice when you finally label a plant
