Garlic scapes are the 'flower' stalks of hard-neck garlic plants. If left on the plant, they form a small bulbils that can be planted to grow more garlic. However, it will take 2-3 years for them to form large bulbs. They are removed from the plant so that all the plant's energy can go towards producing a larger bulb of garlic. They get tougher and hotter the longer they grow. They tend to have a milder garlic flavor.
