🌿 Skirret (Sium sisarum)

A Medieval Perennial Root Crop with Remarkable Sweetness and History

Skirret is one of Europe’s oldest cultivated vegetables — a beloved staple of medieval monasteries, Renaissance gardens, and early kitchen plots across the Old World. This hardy perennial forms clusters of slender, ivory‑white roots prized for their sweet, nutty flavor reminiscent of parsnip, carrot, and water chestnut. Once a favorite of Charlemagne’s royal gardens, Skirret is now a rare heirloom treasure returning to modern homesteads and edible landscapes.

Unlike annual root crops, Skirret grows as a long‑lived perennial, producing harvestable roots year after year once established. Its upright, fern‑like foliage and delicate white umbels add ornamental value, while its vigorous clumping habit makes it a reliable, low‑maintenance food source. The roots can be eaten raw, roasted, boiled, stir‑fried, or added to soups — historically praised as “the sweetest of roots.”

FoxTailTrees offers field‑grown, vigorous divisions selected for strong root formation and robust perennial performance. This is a crop for gardeners who appreciate forgotten foods, historical varieties, and resilient, regenerative edibles.

🌾 Growing Information

Hardiness: USDA Zones 4–9 Light: Full sun to partial shade Soil: Moist, loose, well‑drained soil; avoid heavy compaction Water: Moderate; consistent moisture improves root tenderness Mature Size: 2–3 ft tall foliage; roots form dense clusters Harvest: Late fall through early spring; sweetest after frost Spacing: 12–18 inches apart

Skirret benefits from mulching and occasional division every few years to maintain root size and vigor. In rich soil, roots grow longer and straighter; in lean soil, they remain smaller but intensely flavorful.

🌿 Historical Notes

Skirret was a staple in medieval European cuisine and appears in numerous Renaissance herbals and royal garden lists. Its name derives from the Dutch suikerwortel — “sugar root” — a testament to its natural sweetness. Though nearly forgotten in modern agriculture, it remains a favorite among heritage growers, permaculturists, and collectors of rare edibles.
