Salsify is an uncommon but rewarding root vegetable known as the 'vegetable oyster' for its mild oyster-like flavour when cooked. White salsify (Tragopogon) produces cream-skinned roots; black salsify (Scorzonera) has black-skinned, white-fleshed roots and is generally considered the superior culinary variety. Both are easy to grow but rarely seen in Australian gardens or shops.

Subtropical Growing Tips for Salsify

  • Mammoth Sandwich Island
  • Scorzonera

Key Challenges

  • Long growing season requires consistent care
  • Limited local seed availability

Pro Tips

  • Autumn sowing works well in SEQ for winter root development
  • Black salsify (Scorzonera) is easier and more productive than white salsify
  • Prepare deep beds. Roots grow 25-30cm long

Harvesting Salsify

When ready: Roots are at least 2-3cm diameter at the crown and 20-30cm long. White salsify: foliage begins to yellow in late autumn. Scorzonera: can be harvested in first year or left for a larger second-year harvest.

How to harvest: Dig deeply alongside the root with a fork (at least 30cm deep). Lift very gently. Salsify roots are thin, long, and snap extremely easily. Never pull by the foliage. Water the bed beforehand to soften soil. Cut foliage to 2cm. Do not scrub. Just brush off loose soil.
