Salsify

Tragopogon porrifolius

vegetable

Salsify (also called oyster plant or vegetable oyster) is a hardy biennial root vegetable with a mild oyster-like flavor that gives the plant its alternate name. The slender white taproots grow 6 to 12 in long and 1 to 2 in thick, with purple flowers on the seed stalks of second-year plants. A traditional European root crop now mostly forgotten but worth rediscovering.

✅ Plant alongside

Good neighbors that attract beneficial insects or deter pests

• Carrots — Similar deep-soil culture; rotate together in the bed
• Onions — Sulfur volatiles deter carrot family pests
• Lettuce — Quick early companion that finishes before salsify sizes up
• Radish — Use shallower soil layer and break up surface crust

🛡️ Pest & disease prevention

• Carrot rust fly →

  Row cover salsify like you would carrots; rotate Apiaceae for 3 years

• Aphids →

  Blast with water, encourage ladybugs

• Damage when digging

  Loosen soil with a long spade before pulling; the brittle roots discolor and spoil rapidly if broken

• Bolting in year 1 →

  Sow no earlier than late spring to avoid vernalization triggering an early bolt

🌾 Harvest & storage

Salsify is ready in late fall after a frost or two; cold improves the flavor. Carefully loosen the soil with a long spade before pulling because the roots break easily, and broken roots discolor and spoil within hours. The white roots oxidize quickly when cut, so peel and drop straight into water with a splash of vinegar. Cooked salsify is silky and rich, particularly good in gratins, soups, and creamed dishes.

🥗 Nutrition & benefits

About 82 calories per 100 g raw root with 3.3 g fiber, 8 mg vitamin C, 380 mg potassium, 27 mcg folate, and 75 mg calcium. Salsify is also a notable source of inulin (the prebiotic fiber that feeds beneficial gut bacteria) and iron, more than most other root vegetables.
