Aconitum firmum is a perennial monkshood from the Carpathian region, with indigo hooded flowers on plants up to about 40 cm tall. It is a woodland-edge species best grown in cool, partly shaded, moist conditions, and it is highly poisonous.
Aconitum firmum (Polish: tojad mocny, Czech: oměj tuhý, Ukrainian: Аконіт міцний, Romanized: Akonіt mіtzniy) is a species of monkshood that is found in Southern Poland, Slovakia, and Czechia, with a few instances in Ukraine and Romania.
Like all monkshoods, Aconitum firmum is highly poisonous. All parts of the plant, with the highest concentration being in the roots and seeds, contain aconitine, which is a potent nerve poison.
