Garlic grows underground as a bulb divided into cloves, each wrapped in a papery skin. The plant produces long green shoots (scapes) and sometimes flowers if left to mature.
Examples:
Garlic has been used for centuries in traditional medicine. Modern research supports many of its benefits:

Common in grocery stores, longer shelf life

Stronger flavor, produces scapes (flower stalks)

Fermented at high temperature, sweet and earthy taste

Much larger bulbs, milder flavor (closer to leek)
