Cardoon 'Bianco Avorio' has very thin ribs and produces a straight plant with spines that will grow up to six feet tall. Cardoons are like a giant artichoke only the stems are eaten rather than the flowers.

The plant prefers full sun and light fertile soil. This plant can be used ornamentally as well.
