I was going to order some seeds from The Gesneriad Society (while simultaneously feeling guilty about not being good about collecting seed last year), but then remembered that I have 3 plastic containers of seed in the fridge. Here's the pile:
They are mostly gesneriads. I knew in the back of my mind that some are now several years old, but it hadn't registered that some are nearing a decade in my home, which means they may already by 10 years old from harvest. It's time to sow them all, I think.
By the way, The Gesneriad Society's seed fund is a gem, but it depends on donations. Look around and see if you have any plants with accurate IDs, tag them for controlled pollination, and send in some seed. (I don't think you have to be a member to donate, but purchasing seed from the seed fund is limited to members.)
