  • P = Sow seed
  • Grow in seed trays, and plant out in 4-6 weeks. Sow seed at a depth approximately three times the diameter of the seed. Best planted at soil temperatures between 13°C and 25°C. (Show °F/in)
  • Space plants: 50 - 150 cm apart
  • Harvest in 34-35 weeks.
  • Compatible with (can grow beside): Best grown in separate bed.
  • Cardoon foliage

Cardoon is a tender perennial from the same family as globe artichokes, grown as an annual for its young leaf-stalks.

Blanch the stems. Tie the leaves together in a bunch and wrap paper or sacking around the stems. Or, form a hill of soil around the stem. Harvest four to six weeks after blanching. Cut them off at ground level and trim off the outer leaves.

Culinary hints - cooking and eating Cardoon

Cut off the base and leaves, then cut the stalks into pieces.
Boil the stalks for around 20 minutes until tender: drain, and peel off the surface of the stalks. Add precooked cardoons to a variety of dishes, they go well with mushrooms.

Do I have to start the cardoon in a seed start before that last frost or can I buy cardoons already started at a nursery/garden center?

I find that SEEDS are much better than potted cardoons. Cardoons have really deep roots -- 5 feet or so -- the cardoon drops its root VERY early in it's growth cycle -- for this reason, I prefer to use seeds. It should be noted that Cardoon requires a uniform supply of moisture. Leaves and stalks become pithy when subjected to water stress, making them unmarketable. About 10-12 inches of water, uniformly distributed throughout its growing period may be necessary. Spineless and spiny types exist. The spineless types are preferred. Named varieties are difficult to find in U.S. seed catalogs. Often the only option is a generic cardoon with no variety mentioned. 'Tenderheart' and 'Gigante' can be found in some current catalogs. One may also search European catalogs. Varieties recently available included Bianco Ameliore, Italian Dwarf, Large Smooth, and White Improved. Any of the above can be considered suitable for trial in the Pacific Northwest.

I use to live close to the Saw Mill Parkway in Westchester County in New York..I am looking for the Cardoon seeds that grew in that area. I notice there are several varieties. I would like to know where to purchase these seeds.

You can also buy seeds at www.rareseed.com (Baker Creek seeds) They have a variety called "GOBBO DI NIZZIA" It is great for cooking or just for the flowers.

Do deer eat this plant in the garden ?

They may not, as my sheep and goats do not. It must be the furry texture of te leaves or smell. Good luck, from Tasmania

yes you can grow them in the shade. I have had several varieties and some like the shade more than others. You should still blanch the cardoon though. If you do not blanch it you can still use it... I soak my trimmed, cleaned and chopped cardoons in water with vinegar. Then drain and put in a pot with water and a little salt. Then put it on the stove on high until just before it boils. Remove from heat and rinse. After that cook it or can it. This will remove most of the bitter. It tastes great but I imagine I am loosing some of the flavor when I do this. This is especially handy when I am going to harvest them in the middle of the summer since wrapping then in the heat seems to cause a lot of damage to the stocks. Its best to wrap and harvest in the spring or the fall.
