Cardoon Seeds - purple flowers, Perennial vegetable

Organic Cardoon Seed
Artichoke-flavored leaf stalks.
Cardoons are related to globe artichokes, however different portions of the plant are used. They offer a unique solution to high-end restaurant demand. Cardoons are also grown for their large purple flowers and attractive silvery leave
The leaf stalks and midrib of cardoon have a similar flavor to artichoke when boiled (not for eating raw). Both portions are commonly used as a side vegetable, addition to stuffing, or in soups and stews. Cardoon must be blanched before it can be eaten. To blanch, tie the stalks up firmly and wrap with black plastic or black and white newspaper. If left unharvested, the 3-4' tall plants will produce large purple, thistle-like flowers. The sharply lobed and serrated, silver-green leaves add a unique addition to flower arrangements. Perennial in Zones 6-10.
Cardoon Seeds

Cardoon (Cynara Cardunculus) - Cardoon is considered to be a tender perennial. In cold climates it is often grown as an annual. It is a member of the artichoke family with thick, deeply cut, thistle-like leaves and a violet colored thistle flower head in late summer. Commonly it is called Artichoke Thistle. The Cardoon Artichoke Thistle plant is grown both for eating and for its importance as a medicinal herb, and it easily grows from Cardoon seeds.
A compound found in the leaves of Artichoke Thistle is called cynarin. Cynarin improves the function of both the liver and the gall bladder. It stimulates digestive juices and helps to lower cholesterol. The stems of Cardoon are blanched and used like celery, and the young, tender leaves can be eaten raw or cooked.
How To Grow Cardoon From Herb Seeds: Start Cardoon seeds indoors 4 - 6 weeks before the last frost. Cardoon herb seeds can be started in small peat pots with seed starting mix.

It does not grow well in containers.
