Fun Facts

  • 🌱 Sarcococca hookeriana's fragrance is so powerful that a single small plant can perfume an entire garden on a calm winter day, yet the flowers are so tiny they're easily overlooked if you're not watching for them.
  • 🌱 The plant is native to the Himalayan regions of northeastern India and was named after botanist William Hooker, one of the most influential plant scientists of the 19th century.
  • 🌱 Despite being called 'Sweetbox,' Sarcococca is not related to the boxwood family; the name refers to its small, box-like fruits and compact, neat growth habit.
