Welsh Onion (Allium fistulosum)
 
A true perennial heirloom, Welsh Onion is one of the oldest cultivated alliums, a dependable, cold-hardy onion that returns year after year. Its mild, sweet stalks taste like fresh scallions, while the hollow green leaves add bright flavor to soups, stews, and broths. In medieval Europe, this was a kitchen garden essential, valued for its ability to thrive through snow and provide onion flavor even in the depths of winter.
 
Unlike bulb onions, Allium fistulosum never forms a true bulb. Instead, it multiplies from the base, producing a self-sustaining clump that can feed a household for decades. Easy to grow, long-lived, and beautiful in bloom, it’s both ornamental and edible — an enduring link between the medieval table and today’s garden.
 
Part of our Medieval Garden Collection, this hardy perennial was a vital crop in monastery and cottage gardens, prized for reliability, nutrition, and flavor.
