Please be careful it sounds like monkshood
The monkshood group of plants (aconitum) is toxic and was used throughout Europe as a wolf poison, & in India as a tiger poison, lacing meat left for the mankillers to scavenge. Several of its common names allude to this value: Wolfsbane, Leopard Bane, Tiger Bane, Dog's Bane, & occasionally, a mite absurdly, Wolf's Hat.
