Fun Facts

  • 🌱 Mrs Moon's flowers temporarily lose their fragrance shortly after blooming due to a compound called ionone, which desensitizes our olfactory receptors—the scent returns after a brief break from smelling the flowers.
  • 🌱 Sweet violets have been cultivated and hybridized for over 200 years, with Victorian gardeners creating dozens of named cultivars; Mrs Moon is a heritage cultivar from this era.
  • 🌱 Viola odorata has been used since ancient Greece and Rome, where it was a symbol of modesty and virtue, and Josephine Bonaparte famously loved violets and wore them as a boutonniere.
