  • Description & Ethnobotany
    • Plant Morphology :
      Growth Form: Perennial herb with indistinct bulbs that grows in clusters. The base of the stem is slightly swollen. Leaves held erect. This plant was cultivated from a wild onion that may have been Allium altaicum.
      Foliage: Leaves are bluish-green, pointed hollow tubes (27 – 32 cm long, 0.5 – 0.7 cm wide at the base).
      Flowers: Flowers small and white, have stamens that extend well past the petals. Flowers arranged in round umbel inflorescences and borne on green, hollow stalks similar to the leaves.
      Fruits: Fruit initially green and becomes light brown and papery at maturity. Contains black seeds.
      [Others]: Propagation: Propagate by seed or division of plants.
      Cultivation :
      Although it is able to grow in semi-shade, the leaves tend to bend over. It is best grown under full sun in soil with good drainage and abundant organic matter. In Singapore, this plant grows continuously through the entire year.
      Etymology :
      The genus name “Allium” is Latin for garlic. The species epithet “fistulosum” is Latin for fistular and refers to the hollow tube structure of the leaves.
      Ethnobotanical Uses :
      Edible Plant Parts (Edible Leaves)
      Food (Herb & Spice)
      Edible Plant Parts (Edible Leaves), Medicinal
      [Others]: Food: Commonly added to Asian stir-fries as flavoring. Also used in soups and vegetable dishes. Both leaves and bulbs (white basal portion) are eaten. The leaves contain carotenoids that have antioxidant activity (eg, beta-carotene, lutein). Lutein was shown to improve the vision of patients with age-related macular degeneration, a disease that causes vision loss (Richer et al 2004).
