Black salsify

Under a tuft of long leaves and yellow flowers, black salsify (Scorzonera hispanica) forms a dark-skinned root that peels like a carrot and stands in for potato in mash, stews or thin strips on the barbecue. Give it deep, light, rich, well-drained soil in full sun and the roots come up superb.

Sowing and planting black salsify

Black salsify can be grown from seed or by planting young sprouts.

Sowing black salsify

This method of growing black salsify can be successfully followed by all, even beginners.

Sowing black salsify
Sown straight in the ground in early spring and mid-spring
  • Start at the end of winter, towards early spring and mid-spring, directly in the ground.
  • Dig a ¾ inch (2 cm) groove and space the next grooves 8 inches (20 cm) apart.
  • Cover the seeds with a layer of soil mix about ½ to 1 inch (1 to 2 cm) thick to make sprouting easier.
  • As soon as the first leaves have appeared, you must thin to about 12 inches (10 cm).

Planting black salsify

If you’ve purchased black salsify as young plants in pots, plan to transfer them to the ground in spring.

  • Keep a distance of about 8 inches (20 cm) from one plant to the next and 6 inches (15 cm) between lines to give it space to grow.
  • Exposure must be full sun.

Growing and caring for black salsify

Black salsify is a perennial or biennial that calls for minimal care, perhaps only regular watering in case of high temperatures.

Leaf mulch shields roots and eases lifting
  • As winter draws near, spread dried leaf mulch atop the plants in order to make pulling them out easier and protect them from the cold.
  • In spring, till the ground around them, weed, and then add compost around the stem.

Diseases and parasites that attack black salsify

Black salsify is a vegetable that is quite easy-growing and it fears only very few diseases.

Nonetheless, it may be that your plants attract slugs and caterpillars…

Harvesting the black salsify

One can harvest black salsify from Mid-autumn to mid-spring, simply pulling the roots out.

Harvesting black salsify
Lift the fragile roots gently, from mid-autumn to mid-spring
  • Before the plant goes to seed, cut flower stems.
  • The harvest is often more bountiful during the 2nd year, when larger black salsify roots are produced.
  • When pulling the roots out, proceed carefully so that you don’t damage them, they tend to be quite fragile.

If frost has set the soil hard, wait for a thaw before lifting, since digging frozen ground is difficult and the unyielding soil makes it easy to break or bruise the roots.

Black salsify: what to do and when

From the first grooves drawn at the end of winter to the last roots pulled in spring, black salsify asks for very little. Here is the whole cycle in one glance.

Black salsify: what to do and when
Task When How
Sowing End of winter, early spring and mid-spring Directly in the ground, in ¾ inch (2 cm) grooves spaced 8 inches (20 cm) apart
Thinning As soon as the first leaves appear Thin the seedlings out along the row
Planting young plants Spring 8 inches (20 cm) between plants, 6 inches (15 cm) between lines, in full sun
Mulching As winter draws near Dried leaf mulch spread over the plants
Harvesting Mid-autumn to mid-spring Pull the roots up gently, they break easily

Roots left in place for a second year usually come up larger still.

Cooking with scorzonera

Scorzonera is another name for black salsify. It’s quite easy to cook and prepare, certainly no more difficult than potato or parsnip!

Black salsify - cooking
Use it wherever you would use potato

You can use it in all your recipes to replace potato: mashed, in stews, baked in the over…

In addition, it’s delicious when cut into thin strips and grilled, like on a barbecue.

Simply peel the skin off with a vegetable knife, as you would carrot.

Boiling beetroot whole and unpeeled, then slipping the skins off once cooked, avoids peeling the raw roots and keeps the flesh intact, though the exposed flesh can still stain hands.

All there is to know about black salsify

Difference is that black salsify has yellow flowers
Yellow flowers set it apart from white salsify

Its many varieties like ‘Russian black giant’ and ‘Spanish salsify’, the hispanica variety, must not lead you into thinking that black and white salsify are the same, even though they are quite similar.

It is often confused with salsify which is a different albeit related plant. Black salsify has a higher culinary value.

Black salsify can be identified thanks to its black root and yellow flowers, and white salsify roots are white with pink or blue flowers.

Black salsify has high levels of carbohydrates, allantoin and also vitamins E, B and C. This makes this root a very interesting vegetable as regards nutrition.

Smart tip about black salsify

It is recommended to amend the soil with compost before planting and to loosen up the soil well.
