Did You Know
The artichoke (Cynara cardunculus var. scolymus) (often called globe artichoke) is a variety of thistle that has been improved to form a large edible flower bud. The artichoke is closely related to the cardoon from which we get an edible stem (petiole). Artichokes are native to the Mediterranean region where they have been cultivated since 400 BCE particularly around Sicily and Greece. A plant with a similar name – Jerusalem artichoke – is neither from Jerusalem nor is it an artichoke. This is a type of North American sunflower that produces edible tubers.
Types of Artichoke
Most artichokes produce green flower buds but there are also purple varieties. Varieties also differ in size and shape of the flower buds and how quickly they mature. Green Globe, Imperial Star, Emerald and Purple Sicilian are some varieties that are recommended in our area. Green Globe is the predominant variety in our garden – the seeds are readily available and relatively inexpensive.
When to Plant
Artichokes are tender perennial plants that are not fond of being too cold and can struggle during our long hot Summers. Aggie Horticulture recommends starting seeds indoors about mid-August then transplant the seedlings outdoors after cooler weather arrives – about mid-October. I have also successfully direct seeded artichokes in late September through October. Plants can be damaged by temperatures below 25 degrees warranting covering during cold snaps. By fall, mature artichoke plants (mother plants) can produce basil suckers called pups which can be gently removed from the mother plant and transplanted for a new plant next season. Artichokes need well drained fertile soil and requite consistent moisture for the best production. Although artichokes are a perennial plant, many of our plants do not make it through the summer requiring some reseeding every fall to maintain the overall planting.
Harvest and Storage
Harvest artichokes when full sized, and the buds are still tightly closed. Cut the stem 2 to 3 inches below the bud. The first artichoke harvested from each plant (the king choke) will be the largest. The plant will then produce multiple new stems with smaller heads. These smaller heads taste just as good – you just get to eat more of them. We usually expect to get a dozen artichokes per plant. Artichokes can be stored for a week in the refrigerator. For longer term storage artichokes can be cooked and frozen, pickled and canned. Any artichokes left to mature on the plant will produce a large flower-head with a dramatic neon purple inflorescence.
