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.

• 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

• 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
