Leftovers from the previous season can turn into a delicious spring surprise! These onions grew from ones that were overlooked during fall harvest, and in a spot that hasn’t yet been tilled. There’s an official name for this: volunteering. Strictly speaking, I think a volunteer plant means it comes from seed dropped by a previous crop, or carried in by wind, birds or otherwise. These onions are new growth this year, from mature onions left in the ground over winter, kind of like leaves coming back on a tree. In any case, I think of them as volunteers, but mostly as a tasty treat.
