Artichokes & Cardoon

Cardoon

Cardoon

AR004

60 days. Although cardoon is relatively unfamiliar in American cuisine, it's been relished in the Mediterranean for centuries. Grown for its thick, fleshy stalks, it has a mild flavor reminiscent of artichoke hearts that lends itself to boundless culinary opportunities. Braised and topped with a cheese sauce, slow-cooked in a stew, or cut into sticks and deep-fried, this extraordinary vegetable can integrate into any meal. Typically growing to about 42 inches tall, these artichoke relatives will perennialize in zones 7 and warmer, producing for 6-7 years and reaching a final height of 6-8 feet.

Cynara cardunculus var. scolymus: The flower buds of the artichoke are the harvested part of the plant. Artichokes are reported to contain the highest level of antioxidants of all vegetables!

C. cardunculus: Cardoon is a relative of the artichoke. Instead of consuming the flower as with artichokes, the fleshy leaf stems are eaten. Days to maturity are calculated from date of transplant.

Culture
• Artichokes are a tender perennial that prefer mild winters and cool summers
• Deep, fertile, well-drained soils with a pH of 6.5-7.5 provide optimum growth
• Before a hard frost, cut plants to 8-10 inches above ground and mulch with clean straw to keep the crown from freezing; crown death may occur at 25°F or lower

Direct Sowing
• Not recommended

Transplanting
• Start indoors in January, sow 3-5 seeds per 4 inch pot; thin out small or albino seedlings and keep the strongest plant
• Transplant after danger of frost, but when the seedlings can still receive 10-12 days of temperatures under 50°F to induce budding
• Work in 1 cup of TSC's Complete fertilizer around each plant

Insects & Diseases
Common insects: Aphids
Insect control: Neem, Pyrethrin or Azatrol
Common diseases: Crown rot, powdery mildew, molds
Disease prevention: Avoid overhead irrigation and water-logged soil

Harvest & Storage
• Cut buds before they start to open
• Smaller artichokes are the most tender
• Cardoon can be harvested green or blanched white by wrapping the young stalks with newspaper or piling straw around the plants for 30 days prior to harvest
• Store at 36°F and 95% relative humidity
