Perennial Leek
Allium ursinum
This unique perennial produces annual harvests of tasty greens for soups and sauces. Hardy Perennial Leek dies back in the summer and re-sprouts in the fall. Winter hardy in the Pacific Northwest, it reportedly can be grown in colder regions where temperatures fall to minus 20°F. or below. Mulching with straw or other insulating material is advised during cold winters.
