Skirret (Sium sisarum) is a perennial root vegetable in the carrot family that produces a cluster of slender, sweet white roots from a single crown — and unlike a carrot, the plant comes back and produces again year after year without replanting. It was one of Europe's most prized vegetables for over a thousand years, then all but vanished. It's now finding its way back into serious home gardens, and it's easy to see why once you know the story.
A Root With a Genuinely Wild History
Skirret originated in China and made its way to Europe well before Roman times. Historical accounts describe it as a favorite of the Roman emperor Tiberius, and it remained a staple through medieval Europe and into Tudor England — grown in monastery gardens long before the potato ever arrived from the Americas. The English name itself comes from Middle English words meaning "white root," and in Danish, Dutch, and German, its name translates directly to "sugar root," a nod to its naturally sweet flavor.
It was eventually displaced from mainstream cultivation, most likely because it never matched the sheer productivity of the potato per unit of land — not because of any flaw in flavor. That's part of what makes it such an interesting plant for a home garden today: the exact qualities that made it commercially impractical centuries ago (multiple slender roots rather than one large tuber, slower to bulk up) are irrelevant to a gardener growing a small patch for their own kitchen.
What It Actually Tastes Like
Skirret's roots are consistently described as tasting like a cross between a carrot and a parsnip, with a natural sweetness that intensifies after the roots experience a light frost. The texture cooks up soft and starchy, closer to a potato than a raw carrot. The roots can be boiled, roasted, mashed, or even eaten raw in salads while young and tender.
Pro tip: Harvest skirret roots after the first frost of the season, not before. Cold exposure converts stored starches into sugars, meaningfully improving flavor — harvesting too early misses this natural sweetening entirely.
Why It's a Genuinely Good Fit for a Home Garden
It's perennial: once established, the crown keeps producing for years, unlike annual root crops that need resowing every season
It's low-maintenance once established: beyond consistent moisture, it asks very little
It's genuinely rare: almost never found in supermarkets, making it a distinctive addition for gardeners who want something beyond the usual carrots and potatoes
It self-propagates: after harvest, the crown can be divided into several new clumps and replanted, multiplying your stock without buying new seed
How to Grow Skirret: Step by Step
Step 1: Sow at the Right Time
Sow seeds in late winter or early spring, either directly outdoors after frost risk has passed or started earlier indoors in trays. Germination is notably slow for a vegetable seed, often taking 2 to 6 weeks, so patience in the early stage is normal, not a sign of failure.
Step 2: Choose a Sunny, Moisture-Retentive Spot
Skirret wants full sun and consistently moist, fertile soil — it's genuinely more water-loving than most root vegetables, closer to a marginal or wetland-adjacent plant than a typical drought-tolerant root crop.
Step 3: Sow Shallow
Cover seed with only a thin layer of soil, roughly 1 to 2 times the seed's own diameter — sowing too deep is a common cause of poor germination.
Step 4: Space and Thin
Space plants roughly 20-30cm apart once established, giving each crown enough room to develop its full cluster of roots.
Step 5: Be Patient Through the First Season
Skirret typically needs a full growing season, sometimes closer to a full year, before roots are substantial enough to harvest. This is normal for a genuinely perennial crop — the reward is a plant that keeps producing long after most annual vegetables have been resown many times over.
Step 6: Harvest After Frost, Then Divide
Harvest roots once the foliage dies back for the season, ideally after at least one frost. After harvesting, divide the crown into several smaller clumps and replant a portion to continue the cycle next year.
Frequently Asked Questions
How long does skirret take to grow from seed to harvest?
Skirret typically needs a full growing season, and often benefits from a full year of establishment, before producing roots substantial enough to harvest — it's a slower crop than annual root vegetables like carrots or radishes.
Does skirret really come back every year?
Yes, as a genuine perennial, an established skirret crown will continue producing roots year after year, and can be divided after harvest to multiply your plants without needing new seed.
Why does skirret taste sweeter after a frost?
Cold exposure triggers the plant to convert stored starches into sugars as a natural response, which is why gardeners specifically wait until after the first frost to harvest for the best flavor.
Is skirret hard to grow?
Not particularly, though it asks for more consistent moisture than most root vegetables and has notably slower, sometimes uneven germination — patience in the first few weeks matters more than any special skill.
