Spring Onions Overview

Spring Onions are a hardy type of edible bulb that typically produces bunches of smaller onions that have a mild and crisp flavour. These small onions can also be used for pickling. They are quick and easy to grow and can be grown successionally to provide long white or red stems - also edible - and bright green tops. They have very shallow roots, so they are perfect for container growing and will overwinter.
