Brought to the United States by immigrant gardeners who prized its reliability and exceptional flavor, it quickly became a staple of the American vegetable garden and a fixture in seed catalogs throughout the 1800s and early 1900s. Leeks themselves have been cultivated for over 3,000 years — beloved by the ancient Egyptians, Greeks, and Romans as a food of both sustenance and sophistication.

Allow the seed heads to fully dry on the plant before harvesting — cut the entire stalk and hang upside down over a paper bag to catch seeds as they fall.

Despite its name, it has no connection to Wales; the name derives from the Old English word \u003cem\u003ewelsche\u003c\/em\u003e, meaning \"foreign\" — a nod to its origins in Siberia and China, where it has been a kitchen staple for millennia. Brought to American gardens by early settlers and Asian immigrants alike, Evergreen White Bunching became a beloved garden standby for its remarkable cold hardiness, continuous harvest, and mild, versatile flavor.
