Botanical Characteristics of Garlic

  3. Inflorescence: Garlic plants produce an inflorescence in the form of a long, slender stem topped with a cluster of small, star-shaped white or pinkish blossoms. However, in many cases, these flower stalks, known as scapes, are removed to direct energy toward bulb development.
