In its native habitat it grows in damp shady places including deciduous forests. All parts of this plant are extremely toxic.

The etymological root of the binomial name Aconitum is from the ancient Greek name for this plant and is loosely translated as ‘unconquerable poison’. Lycoctonum is derived from the Greek lukos meaning ‘wolf’ and kteinw menaing ‘to kill’.
