Aconitum variegatum - Wolf’s Bane, Monkshood
Aconitum is thought to be from the Greek ἀκόνιτον - “without struggle”. And it is without struggle that this plant causes death.
This beautiful perennial flower can be seen through the autumn months in forests and taigas in Europe, and is popular as an ornamental in gardens, lending color long after summer blooms have faded.
