Hetty,
I posted about my 'white ghost' just dying on me. I plant to re-buy one in spring. My crested ones seem ok for me. Paul had a 1/2 green and 1/2 white that I would love to have a piece of. Like all the others in our cold northern states I will wait till spring to begin trading or buying stock.
I have some Agave vivipara (angustifolia) variegate pups to give out. Too cold now to ship out.
There free for the asking. Don't know about shipping? Got till spring to figure out.
I got this big cactus, don't know what but it starts easily with a cutting for whoever.
