Sium sisarum – Skirret Other common names: crummock, jellico
Skirret, a starchy root vegetable that belongs to the carrot family, was once a popular crop in Europe during Roman times. The Emperor Tiberius was particularly fond of it, and even demanded it as a tribute from the Germans. It was the main root crop eaten in Europe before the potato was introduced. Skirret has a unique taste between a carrot and parsnip and can be found in sweet and savoury dishes. The name “skirret” is derived from a Germanic origin meaning “sugar root”. However, despite its popularity in the past, skirret has faded from gardens and tables over time.
Skirret is a vegetable that is quite easy to grow once you know how. Unlike most of its relatives, it is a perennial plant that produces a bunch of roots, making it easy to lift and replant. Skirret can be grown from seed and produces a single “crown” consisting of several shoot buds around the base of a stem, with a cluster of roots attached. To form a clump made from several crowns, a crown can be divided easily. However, some of the roots in a cluster are not worth picking, so it’s best to dig up the clump, snip off the roots that are worth having, and replant.
Skirret roots can sometimes have a woody core that can’t be softened even after prolonged cooking. This issue is more common in young plants but may disappear as they grow older. It can also be caused by insufficient water during the growing period. Alternatively, it may be due to genetic factors that vary from plant to plant.
Another yield from skirret is the immature flower stems, which have a nice carroty taste when boiled or steamed. They are fairly substantial and produced in reasonable volume, but they are fast-growing and soon harden off, so if you want more than a brief harvest you will have to freeze some.
Skirret can be grown from crowns, but it’s not easy to obtain them. You either have to spend a lot of money or start from seed. Skirret is not easy to grow from seed because it needs a period of winter cold to germinate. If you’re planning to grow Skirret from seed, make sure you source current-year seed in the autumn and stratify it right away. The seed loses viability quickly, like many plants in the Apiaceae family.
