Artichoke Market Overview

The globe artichoke (Cynara scolymus L.), usually just called “artichoke,” originated in the Mediterranean region. This herbaceous, thistle-like plant is produced for its immature, edible flower buds. It was first brought to the United States in the 1800s, where it was grown in Louisiana by French settlers and in California by Spanish immigrants.
Today, artichokes are sold fresh, frozen, or canned, often in the form of marinated artichoke hearts. When cooked without seasoning, the vegetable’s tender petals carry a subtle flavor often compared to the taste of fried egg white.
Italy is the world’s largest producer, followed by Egypt, Spain, and Peru. In the United States, commercial production is limited almost exclusively to California. Washington and Oregon also grow artichokes, but in lesser quantities.

Types & Varieties of Artichokes

There are two primary classifications: Italian and French. The Italian or Green Globe (also known as Heirloom), is the most popular, with a long, more pointed bud and should not be confused with the Jerusalem artichoke, a root crop. The French type, has a short, thick, rounded bud with a flat end and is not as marketable due to lower yields and packing challenges.
California’s Green Globe artichokes are planted as a seasonal, slow-growing perennial and take nine months to mature from multishoot rootstock. Annual varieties are cultivated through transplants or direct seeding, have a single producing stalk, and thrive in the state’s coastal regions. Varieties include the Imperial Star, Desert Globe, and Big Heart.

The Cultivation of Artichokes

Best suited for frost-free areas with mild, foggy summers, artichokes are a cool season crop. Plants flourish in temperatures ranging from 55°F at night to 75°F during the day.
Temperatures near freezing may cause buds to rupture, with a white, blistered appearance. Although the damaged skin will eventually turn brown, the artichokes are still edible. Prolonged exposure to below-freezing temperatures (28° to 30°F) can completely destroy the buds, causing them to turn black within hours.
Although plants may adapt to a variety of soil types (with the exception of heavy clay or light sand), they thrive in fertile, deep, and well-drained soil with ample irrigation.
Harvesting artichokes is extremely labor-intensive. Field workers pick them by hand, cutting the ripe plants from stalks with a short knife. Artichokes are then placed into canastas, baskets carried on their backs.
When full, canastas can weigh from 80 to 100 pounds.  Because artichokes are easily bruised, growers try to avoid overhandling and pack in the ?eld rather than a shed.
Artichokes are sorted by size and packed in waxed cartons, hydrocooled, and moved to cold storage. Artichokes may be stored for one to two weeks at 32°F.

Pests & Diseases Affecting Artichokes

Artichoke plume moth larvae are small, wormlike pests that feed on the ?oral buds, making them unmarketable. Larvae may also feed on developing shoots.
Aphids cause leaves to curl and turn yellow, stunting the plant. Secreted honeydew can result in sooty mold on leaves.  Snails and slugs are a concern in winter and feed on all parts of the plant. Other pests of concern include spider mites and earworms.
Curly dwarf causes curling and distortion of leaves, resulting in smaller, stunted plants and deformed buds. Botrytis rot, also known as grey mold, affects previously damaged areas and can quickly spread.
Bacterial crown rot causes stunting with wilted leaves and rotting roots. Other diseases of note include powdery mildew, damping o?, and verticillium wilt.

Grades & Good Arrival of Artichokes

Artichokes are divided into U.S. No. 1, U.S. No. 1 Long Stem, and U.S. No. 2 grades. Standards for the first two categories require artichokes to be properly trimmed, fairly well formed and not overdeveloped, fairly compact, free from decay and damage, and of uniform size.
U.S. No. 1 Long Stem requires smoothly cut stems of at least 8 inches in length. For U.S. No. 2, artichokes should not be overdeveloped or have badly spread globes, be free from decay and damage, and be of mostly uniform size.

Generally speaking, the percentage of defects shown on a timely government inspection certificate should not exceed the percentage of allowable defects, provided: (1) transportation conditions were normal; (2) the USDA or CFIA inspection was timely; and (3) the entire lot was inspected.
