Did you know

  • Also called wolfsbane — medieval Europeans tipped arrows and spears in its juice to hunt wolves and bears.

  • It's the legendary werewolf-repellent plant of folklore, said to protect against shapeshifters and witches.
  • The Greek myth says it sprang from the saliva of Cerberus, the three-headed dog, when Heracles dragged him out of the underworld.
  • Despite its lethal reputation, it's a stunning back-of-border perennial whose hooded indigo flowers bloom when most others are fading in late summer.
