Chard is a magical vegetable, it seems. Its leaves substitute spinach, its stems substitute asparagus and such, you can continuously harvest it and it just regrows, the planting is "whatever, as long as there's vaguely some sun somewhere", and in some cases it'll even continue growing through winter
@gsuberland So, funny thing, neither have I, I think! It doesn't seem to be generally available in stores here. I'll be planting it this year, though.
