I've just discovered that you can eat hostas! I was watching a YouTube video from 'Lovin on the Land' and noted that they are growing them for this purpose. Has anyone tried this?
I can recommend their vlog as a counterpoint to the usual allotment gardening channels. The couple are based in Pender Island off British Columbia in what appears to be an idyllic situation, and are only eating what they grow. I've only just found them so not been following along but I'm impressed by their commitment and creativity.
