Definitely an interesting shade. I've only seen the pink ones before.

Lovely days, crisp frosty nights, lots of passive solar heating, have to keep an eye on those sensitive plants that burn at this time of year. Oh, and thick freezing fog last night, that was fun

Everything has germinated, Colin, except for the freebie Aylostera seed although I think I see something even there. Lithops viridis is a single microscopic green speck but I'm keeping my fingers crossed for more. Lithops comptonii, reputed to be nearly as difficult, has produced quite robust cotyle...
