Compositae Cynara cardunculus L.
Source: Magness et al. 1971
Cardoon is closely related to globe artichoke. Growth is up to 6 feet, with large pinnate, prickly leaves. In cultivation, plants are grown from seed. When leaves are near fully grown they are tied together near the top, and plants are banked with straw and soil - or other material - to blanch the leaf stalks or petioles. These are edible parts, but are inedible unless blanched. Cardoon appears not to be grown commercially in the U.S. In exposure of edible parts during growth, the plant is comparable to celery.
Production in U.S.: None commercial.
Use: Fresh, as pot herb.
Part of plant consumed: Petioles and main ribs.
