Cardoon - Cynara Cardunculus Herb Plants
Prefers a light warm soil and an open position in full sun. For best results, this plant requires plenty of moisture in the growing season and a good rich soil, though another report says that it is drought tolerant once established. Tolerates most soils including heavy clays of both acid and alkaline nature, especially when grown in heavier or more spartan soils. Plants are reasonably wind resistant.
This species is hardy to about -10°c. Plants are more likely to require protection from winter cold when they are grown in a heavy soil. Wet winters can do more harm than cold ones. Sow early spring in a greenhouse. Germination is usually quick and good, prick out the seedlings into individual pots as soon as they are large enough to handle and plant them out into their permanent positions during the summer.
