Did you know

  • Bog rosemary is named after Andromeda, the Greek princess chained to a rock in the sea—Carl Linnaeus named the plant in 1732 because he saw it growing on rocky islands surrounded by bog water that recalled Andromeda's predicament.
  • Linnaeus wrote a famously poetic passage about discovering bog rosemary on a Swedish lake island, where the dragonflies hovering around it suggested the sea-monster threatening the original Andromeda.
  • Each pink urn-shaped flower hangs upside down on a thin red stalk—delicate enough that they tremble in the lightest breeze, like tiny lanterns over a peat bog.
  • Despite its delicate beauty, bog rosemary is highly toxic—it contains andromedotoxin, which can cause vomiting, low blood pressure, and dangerous heart symptoms if eaten by livestock.
  • Honey made from bog rosemary nectar can be toxic to humans—'mad honey' poisoning has been recorded in northern Europe and Turkey since ancient Greek times.
