Almost all of the artichokes grown in the US come from California, but research is now underway to study the ability of growers in northeast Florida to grow artichokes, a high value crop that would be grown in the cool season. Since artichokes require 250-500 hours below 50 degrees to form buds, some artificial means would be used to induce bud formation.
