Scorzonera
Scorzonera hispanica
Overview
Also called black salsify, scorzonera is a perennial root vegetable with dark, bark-like skin and creamy white flesh that has a more robust flavor than white salsify. It was once called 'viper's herb' because it was believed to cure snakebites. As a perennial, roots left in the ground grow larger each year, and the plant also produces edible flowers, buds, and young leaves.
Growing Conditions
How to Grow Scorzonera
Scorzonera (Scorzonera hispanica) is a forb/herb that grows to about 3 feet tall and 2.5 feet wide.
To grow scorzonera, give it full sun. It is hardy across USDA hardiness zones 5–9. Plant it in deep, loose, fertile, well-drained sandy loam, at a slightly acidic pH of 6–7.5. It does best with even, moderate watering.
Exact sowing, transplanting, and harvest months shift by climate zone — the planting calendar below lays them out for cool through hot regions. Its flowers appear from May through July, offering high value to pollinators. It feeds two tables at once: yours and the pollinators’.
Companion Planting & Soil
Scorzonera grows well alongside carrot, lettuce, and onion.

Uses
In the Kitchen
In the kitchen, scorzonera turns up in more than one form: roots peeled and roasted, braised, or sautéed; young leaves and flower buds added to salads; roasted root used as a coffee substitute in some traditions.
Medicinal & Folk Use
In herbal and folk tradition, it has been valued in several ways: high in inulin prebiotic fiber; rich in iron, calcium, and potassium; traditional European tonic for liver and digestion. These are traditional uses, not medical advice.
Beyond the Garden
Scorzonera earns its keep past the plate, too: perennial root that improves in size over years; rare heirloom vegetable for specialty gardens.
