I love the "if it grows all year, we should be eating it all year" idea. Parsley for sure, mine was only unavailable for two months here, not far from where @futuremind lives. ong

I've gotten very fond of dandelion root this year. Fresh, lightly cooked, it's very good! I let my dandelions go to attract early bees and pollinators, so I have a ton of the stuff. I think we could eat that year round too, as long as we could dig it out of the frozen ground.
