Are Cardoons the Same as Artichokes?

Found in the wild along the Mediterranean, from Morocco and Portugal to Libya and Croatia, a cardoon is a thistle that tastes like a bitter version of a giant artichoke with small, prickly flower heads. But unlike an artichoke, you eat the stems, not the flower buds.

How can you tell the difference between an artichoke and cardoon?

Physical Differences

Both possess silvery foliage and violet, thistle-like flowers, although artichokes produce larger flower buds with a tighter, more globular shape and less pronounced spines. Also, cardoons possess a rangier, less tidy growth habit, although both plants grow to roughly 3 to 5 feet in height.
