Most roots go out of season by the start of May, but burdock root, which tastes like a combination of potato and artichoke, stays in season from spring to fall, and it grows in Tarrywile Park too. At this time of year, you can also peel the immature flower stalk, parboil it, and use it like artichoke hearts.
We may even get the first wild berries to come into season as summer approaches. Wild strawberries, juneberries, and mulberries may just be ripening.
