Culture Notes
This monkshood grows best in rich moist to well-drained soils and sandy soils. It prefers regular watering during dry weather. If grown in sandy soils provide frequent watering as monkshood resents drying out. Avoid hot locations. Plant this perennial in full sun to light or open shade. Stems are stronger in full sun, but flowers will tend to fade faster. In light or open shade the flowering stems can lean, but the intense flower color will last longer.
Geek Notes
The drug 'aconite' is made from the roots of Aconitum. All parts these plants are poisonous.
