The genus Aconitum belongs to the family Ranunculaceae  and as with many other genera of that family Aconitums are poisonous. In fact most are so poisonous that one English common name is  "wolf's bane" and they were a popular way for  royalty of centuries past to get rid of their competition. Aconitums are hardy and can tolerate some shade, but too much shade can decrease flowering.  They prefer fertile, moist, yet well drained soil as most species are native to mountain meadows in the Northern hemisphere.


Division in spring.

Seed - needs cold stratification, best sown in September - November.

Seed covered and stored at 20°C (68°F) for 2-4 weeks and then stored outside until germination. Germination can be slow and seed may germinate a year later. During the cold stratification period the temperature needs to be below -5°C (23°F) for at least 4-6 weeks. Optimum germination temperature is 5-12°C (40-55°F).

A tall, wind tolerant plant that generally does not need support. It grows best in fertile, humus-rich, well drained, moist soil, but can tolerate most soil types. Hardy and easy to grow. A highly toxic plant.
