Depending on the time of year, you may be lucky enough to find either green garlic or garlic scapes. The scapes are the long, green, flower-bearing shoots that signal the first growth of the garlic plant. They are harvested in late spring or early summer by snipping them off the forming bulb. Green garlic is the immature garlic bulb. Looking something like scallions, these are pulled from the ground to thin the crop. When cooked, both yield a delicate garlic flavor.
