Cardoon

Cardoon, also known as Texas Celery, artichoke thistle and cardi, requires a long growing season, so starting seeds in the earliest part of spring is advised. In general, cardoon grows the largest in good, deep soil and with frequent watering. Pests are minimal, and the perennial plants are drought-tolerant, although a lack of water reduces its size. Cardoons need to have their stems blanched or they will be intolerably bitter. A month of being tied up and kept in the dark will make the stems much sweeter.
