Garlic Chives (Allium tuberosum), also known as Chinese Chives or Nira, are a perennial Allium species with flat, solid leaves and a distinctive garlicky-onion flavor that distinguishes them from ordinary chives. A staple herb in Chinese, Japanese, and Korean cuisines, garlic chives are used far more extensively in East Asian cooking than regular chives.
• The species epithet "tuberosum" refers to the short, thickened rhizomes from which the plant grows
• Flat, solid leaves distinguish garlic chives from the hollow, tubular leaves of regular chives (A. schoenoprasum)
• The white flowers are larger and more showy than regular chives and are highly ornamental
• In Chinese, called "jiu cai" (leek) or "nira" in Japanese — one of the most commonly used herbs in East Asian cooking
• The flowers are also edible and considered a delicacy
• Very easy to grow and highly productive — cut leaves regrow quickly
• Cultivated in China for at least 2,000 years
• Widely used in traditional Chinese medicine as a warming, yang-enhancing food
• Spread throughout East and Southeast Asia as a culinary staple
• Introduced to Europe and North America as both a culinary herb and ornamental plant
• Has naturalized in parts of the southeastern United States
• Sometimes considered invasive due to its vigorous self-seeding habit
• The genus Allium contains approximately 750 to 900 species worldwide
