When to Plant Salsify in Canberra — Cold / Highland Guide
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.

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.
