Scorzonera

Scorzonera (Scorzonera hispanica) is a perennial root vegetable in the sunflower family, grown for its long, black-skinned taproots with ivory-white, delicately flavoured flesh. Native to southern Europe, it thrives on deep, loose, nutrient-poor soils and tolerates frost in the ground. It needs a long growing season and rewards patience with roots that can be left in the ground and harvested over successive years.

Growing

Direct-sow as soon as the soil is workable and frost-free — once soil temperatures reach around 5 °C. Sow seeds 2 cm deep in rows spaced 40–50 cm apart. Thin seedlings to 10–15 cm within the row. Choose a deep, sandy or well-worked loam bed free of stones to prevent forking. A late-summer sowing can also succeed, giving the roots an early start the following year. No indoor starting is necessary or recommended.

Care

Water consistently during dry spells to prevent roots from splitting or becoming woody, but avoid waterlogging. Scorzonera requires little feeding on reasonable soil — excess nitrogen produces leafy growth at the expense of root development. Keep beds weed-free, especially early in the season. Mulching retains moisture and keeps the soil loose for easy root expansion.

Harvest

Roots are ready from around 115 days after sowing. Dig as late as possible — leaving roots in the ground until the first frosts improves flavour. Use a fork and dig deeply, working carefully alongside the root to avoid snapping it. Roots left in ground over winter can be harvested as needed while soil is not frozen, or lifted and stored before hard freezes. Unharvested plants will flower in their second year.

In the kitchen

Scorzonera has a mild, slightly sweet flavour reminiscent of oysters or artichokes. Scrub and peel just before use (the skin discolours quickly — drop peeled pieces into acidulated water). Boil, steam, roast, or sauté; use in soups, gratins, or as a side vegetable. Young leaves and flowers are also edible raw in salads.

Storing

Lifted roots keep best in a cool, dark place packed in slightly damp sand at 0–4 °C for up to several months. Alternatively, leave roots in the ground and harvest as needed while temperatures remain above hard-freeze level. Do not store at room temperature — roots dry out and become fibrous quickly.
