Description of the plant:
Autumn or azure monkshood is a showy perennial flowering from late summer till autumn. Arendsii is a variety producing erect racemes of large, hooded flowers that are more indigo blue rather than violet. They appear from September till October along sturdy stems that grow just over a meter tall. The wise thing about this monkhood is that since the blooming time is very late in the season, it offers something more to gain your attention early in the season: very attractive, deeply cut, dark green, glossy leaves. Monkshood is a popular cut flower. It is used especially in Chinese medicine, yet some caution is advised when working with the plant as all its parts are highly poisonous. Wearing gloves is suggested.
It grows in almost any moist soil but prefers deep and humus-rich soil. It likes full sun or part shade. Fertilizing is not necessary but may enhance flowering – producing shorter racemes just below the main one. Fully hardy to about -40 °C (USDA zone 3).
