Today was a great day. I found an old tray of sarmentosum I thought had slid down into the creeck behind my house...
It was between two large rocks downstream right from where I was looking (How could I have overlooked it?!?) And the plants were still alive, just under somme leaves.
I found a variegated sarmentosum, with cream/yellow variegation that fades to white. The variegation seems to be really stable.
