Artichoke and Cardoon are most ornamental perennials with attractively large, silvery-grey, deeply dissected foliage in a dense basal rosette and an impressively tall inflorescence with large, thistle-like, bright purple flower globes. The flower heads of the cultivated Globe Artichoke are widely used as a vegetable in the Mediterranean cookery, whereas several wild species are used to extract medicinal active substances. For any rich, very well drained, preferably stony soil in a protected spot in full sun. In colder climates protect the dormant rootstock against freezing through and permanent wetness with a dry mulch layer in winter.
Sow flat from spring to mid summer in any well drained, sandy soil. Keep pots in full sun and soil only slightly moist. Carefully transplant the fleshy rootstock in autumn.
All are USDA Climate Zone 7.
