My newest plant obsession is fragrant cactuses (especially the tropical
epiphytes) which are definitely OT for PBS. However, while searching for
sources for the more obscure varieties I encountered the genus Wilcoxia.
These are cactuses with tuberous roots like Dahlias. They're fascinating!

Are PBS members growing these? I can't find any record of them being
offered in the BX. The PBS wiki does have a page for a related genus, but
not for Wilcoxia:

My first attempt is going to be Wilcoxia schmolli. I just ordered some
seeds. Some cool pics of it can be seen here:
