Monkshood
Aconitum napellus
Family: Ranunculaceae · Also called Wolfsbane, Aconite, Devil's Helmet, Delphinium napellus, Napellus vulgaris
Green & Fresh · Summer–Autumn bloomer
Monkshood is the dark aristocrat of the autumn border, tall, elegant spires of hooded flowers in intense violet-blue that add drama and depth to any planting. Each flower is shaped like a monk's cowl, concealing the reproductive parts within. It's the last great spire flower of the season, bridging summer and winter with gothic elegance.
caution, chivalry, misanthropy
In the Victorian language of flowers, monkshood means “Beware, a deadly foe is near”. One of the most poisonous plants in the European garden, all parts, especially the roots, contain aconitine. It was used to poison arrow tips, wolf bait (hence 'wolfsbane'), and allegedly used in assassination plots throughout history. Despite this, it's been grown in gardens since medieval times for its stunning blue flowers. Handling without gloves can cause numbness.
Did You Know?
Monkshood is so toxic that even touching the leaves with bare hands can cause numbness and tingling that lasts hours. Ancient warriors dipped arrows in aconitum extract, and it appears in Shakespeare, Greek mythology (sprung from Cerberus's drool), and Harry Potter. Despite all this, bumblebees visit it safely, they're immune to the alkaloids.
Mountain meadows, stream banks, and damp woodland in cool climates
Monkshood is native to Europe, Northern Asia. It naturally grows in mountain meadows, stream banks, and damp woodland in cool climates.
Scent Profile
“Faintly acrid, not a pleasant scent flower, and not one you should get close enough to smell deeply. The hooded blooms are designed for bumblebee pollination, not human appreciation of fragrance.”
