Fun Facts

  • 🌱 The Vitamin Plant earned its common name because its berries are exceptionally high in vitamin C—often containing more per ounce than oranges or lemons.
  • 🌱 The fuzzy, reddish appearance of new growth gives it the alternate name 'Red Ivy,' though it is not a true ivy but a tropical vine in the Vitaceae family (grape family).
  • 🌱 In its native African habitat, the plant has been used for centuries by local communities as both a food source and traditional remedy for immune support and cold prevention.
