Skirret: complete guide

Overview

Skirret (Sium sisarum) is a traditional root vegetable from the carrot family (Apiaceae) native to Eastern and Southeastern Europe through Southwestern Siberia to Northern Afghanistan. This overlooked vegetable deserves renewed attention for its excellent nutritional value, sweet roots, and minimal requirements. Though many gardeners don't know this crop, it was greatly prized in medieval Europe and Asia for its sweet, unique roots.

Appearance and bloom

Skirret forms a compact plant 60 to 90 centimetres tall with feathery gray-green foliage resembling willow fronds. In the second year (rarely in first), the plant displays elegant white to yellowish-white flowers in umbrella-shaped flower clusters typical of the Apiaceae family. The roots are very thin and white, often branched and fragmented, reaching depths of 30 to 60 centimetres. Upon maturity, they develop a sugar-like structure.

Ideal location

Skirret thrives in sunny to partially shaded locations receiving at least 4 to 5 hours of daily direct sunlight. In areas with very hot summers, afternoon light shade proves beneficial. The plant grows well in open gardens, vegetable beds, and container cultivation. Sunny locations ideal for optimal growth, though the plant adapts to less ideal light.

Soil

Skirret performs best in well-draining, loose, fertile soils. The plant prefers neutral to slightly acidic soils with pH 6.0 to 7.0. Compact, heavy clay soils must be improved with compost and sand to enable deep root growth. Strongly acidic soils (pH below 5.5) can create problems. Adding organic matter helps roots develop better.

Watering

Skirret requires regular watering, especially during growth and root development. Soil should remain consistently moist (not waterlogged). In dry periods, water daily to achieve optimal root expansion. Inconsistent watering can cause root cracking. In the second year (flowering year), less water is needed.

Pruning

Skirret requires no pruning, though removing dead leaves can occur anytime. After flowering, flower stems can be removed. During the first year, no pruning is needed; focus on root growth.

Maintenance calendar

April-May: Sow directly into ground. June-July: Water regularly, control weeds. August-September: Prepare for harvest or overwintering. October-November: Harvest possible in mild winters; otherwise harvest next spring. December-February: Rest, minimal care. March: Next year growth (if not harvested).

Winter hardiness

Skirret is extremely hardy, tolerating temperatures down to -15 to -20 degrees Celsius. In fact, winter cold often improves flavor by converting starch to sugar (similar to potato). Roots can remain in the ground through winter and be harvested in spring when temperatures rise.

Companion plants

In vegetable beds, Skirret pairs well with other roots such as Carrot and Parsnip. Also compatible with leaf greens such as Lettuce and Spinach. Avoid close planting with other Apiaceae members (Parsley, Dill) due to potential cross-pollination. In aesthetic gardens, the fine foliage pairs well with taller plants.

Closing thoughts

Skirret is a valuable underappreciated crop deserving rediscovery in modern gardens. With its simple cultivation requirements, exceptional nutritional value, and unique flavor, it offers much for home gardeners. Harvesting and cooking can be done in many recipes.
