How to grow Black Salsify

  • Full Sun

    +
  • Medium

Loose, rich soil is best because roots can break easily when harvested.

Plant in a location that enjoys full sun and remember to water moderately. The USDA Zones typically associated with Black Salsify are Zone 1 and Zone 10. Planting Black Salsify in loamy soil with a ph of between 6.0 and 6.8 is ideal for as it does best in weakly acidic soil. Keep in mind when planting that Black Salsify is thought of as hardy, so it can be safe to leave outdoors for the majority of winter (although if in doubt, using a row cover is often a good idea).

Growing Black Salsify from seed

Direct sow after last frost through July. May soak seeds before planting or water well directly after planting.

Aim to sow 0.39 inches (1.0 cm) deep and try to ensure a gap of at least 3.9 inches (10.0 cm). Soil temperature should be kept higher than 0°C / 32°F to ensure good germination.

By our calculations*, you should look at sowing Black Salsify about 0 days after your last frost date .

Transplanting Black Salsify

The soil temperature for optimum germination is pretty high, though they are viable down to rather cool temperatures. In our climate, most sources agree that you can sow from “early spring” till as late as mid-July. Now scorzonera, like most roots (carrots are the notable exception) are slow-growing, with 120 days as a typical “days to maturity” figure. Moreover—again, like almost all roots—they are much improved by exposure to at least one good frost, so we don’t want them ready too soon, though they don’t get woody when large; as long as we can still get them out of the ground is as late as we can take them (4)

As Black Salsify is hardy, ensure temperatures are mild enough to plant out - wait until after your last frost date to be on the safe side.

Harvesting Black Salsify

Growing in deep containers will make harvest easier, roots are delicate and easily breakable.

Flavor improves after frost.

Roots may be left in the ground and harvested as needed during the winter if the climate is mild enough so that the ground can be protected against freezing by mulching.

Roots can be stored in the refrigerator or a cool but not freezing location for several months. Cut off the tops before storing.

Leaves can be harvested for salad greens.

Seed Saving Black Salsify

Self sows.

Beware: scorzonera seeds are notoriously short-lived. If you aren’t saving you own seed annually, don’t try to be cheap and use last season’s leftovers—get fresh seed every year. (4)
