The foliage is tender, juicy, and offers a mild flavor, ideal for harvesting as young leaves or at maturity. Highly adaptable and reliable, it is easily sown in early spring and tolerates successive sowings well.

Planting and maintenance:
Sow as soon as the soil can be worked in spring, then continue sowing every two weeks as long as the weather remains cool.

Harvest leaf by leaf or the entire plant before it goes to seed to preserve the tenderness of the foliage.
