  • Description & Ethnobotany
    • Plant Morphology :
      [Others]: Fast-growing, aggressive climber or creeper. Considered an invasive weed in several regions where it has become naturalized. Has a tendency to over-run nearby plants and kill them by smothering them, or blocking off sunlight. Also exhibits allelopathic properties -- plant secretes inhibitory chemicals to prevent growth or germination of nearby plants.Reported to grow up to 27mm per day, and may cover more than 25sqm in a few months. Besides rapid growth-rate (hence the common name 'Mile-A-Minute'), the plant may produce as many as 40,000 seeds per year -- these are dispersed by wind, or carried on hair, fur and clothing. Plant is able to root from stem fragments as well.Nectar plant for Common Pierrot (Castalius rosimon) and Peacock Pansy (Junonia almana) butterflies. Plant commonly attacked by aphids, resulting in distorted curled leaves. Triangular leaf shape said to be inspiration for design of canopy walk floor-panel used on aerial walkways for Southern Ridges, Singapore.
      Ethnobotanical Uses :
      Medicinal (Plant has anti-microbial properties. Macerated plant applied to new wounds, insect stings and other skin irritations. Leaves boiled in seawater can be used to relieve skin itch.)
      [Others]: During World War 2, this species was introduced to India as a means to camouflage airfields.
