Skirret (Sium sisarum)

Skirret is a traditional European perennial root vegetable that was widely grown from medieval times through to the 19th century, valued for its sweet, clustered roots. Often referred to in old texts as a “sugar root,” it produces slender, finger-like roots that are sweeter and more aromatic than carrots when cooked.
The flavour is gently sweet, nutty, and floral, with a soft, creamy texture when roasted, boiled, or pan-fried. At KoruKai Herb Farm, we especially enjoy it simply sautéed in butter, where its natural sweetness really shines.
Skirret forms a clump of multiple edible roots from a single crown, making it a productive and rewarding perennial vegetable for the home garden. Once established, plants improve in yield each year as the root system expands.
