I bought a couple of small seedlings last summer ('20).
An Aurea from Peter Lin and 2 Rosita's from Brent Baker. I had already paid Brent for a larger one which he was out of when he got my payment so he sent me 2 small seedlings.
All 3 of them have at least tripled in size in the year I have had them so I guess I'm doing something right.
aurea is definitely circulating around in Australia. I bought one, and the humidity is quite ok here. In this pic, I looped one of the roots around and popped it back into the scoria heheh pic link
