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.

How to Grow Salsify in Cold / Highland Australia

When to Plant

Sow direct in spring into deeply dug, stone-free soil. Roots size up by autumn and can stay in the ground through winter to be dug as needed.

Soil
Deep, loose, stone-free soil. Dig to at least 30-40cm depth. Light sandy loam is ideal. Avoid heavy clay or stony soil which causes forked, stubby roots. Prepare with well-rotted compost dug in deeply.
pH Range
6.0-7.5
Sunlight
Full sun to light shade
Spacing
12cm apart, 35cm between rows
Watering
Consistent moisture throughout the long growing season. Deep watering once or twice weekly. Irregular watering causes tough, woody roots.

Companion plants: Carrot, Lettuce, Onion

Avoid planting near: No significant antagonisms known

Grow before, grow after

Salsify belongs with the root crops, the roots and alliums turn of a four turn bed rotation.

Grow before it
Fruiting crops (Tomato, Capsicum, Zucchini)
Grow after it
Legumes (Beans - Dwarf, Peas, Broad Beans)

Give the bed 3 turns before root crops go back in. Roots fork and go leafy in fresh manure, so they take the bed after the heavy feeders have used it.

Cold / Highland Growing Tips for Salsify

Recommended Varieties

  • Mammoth Sandwich Island
  • Scorzonera

Key Challenges

  • Short growing season for a slow crop
  • Cold soil delays germination

Pro Tips

  • Start as early as possible after last frost
  • Scorzonera can be left in the ground over winter and harvested in year two for larger roots
  • Mulch heavily for winter protection if leaving in ground

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.
