Aconite, also known as devil's helmet, wolf's bane, monkshood or blue rocket, is an herb perennial found wild in mostly mountainous areas. Characterized by its blue triangular-shaped flowers, aconite grows best in soil that retains water while still draining, such as the banks of moving creeks. Aconite is highly poisonous. While once used in many homeopathic and medicinal purposes, today it is advised to never ingest it or touch it without your skin covered. Still, many gardeners covet it for its striking beauty, and even more authors refer to its deadly properties in their work.
Aconite can grow up to four feet tall, so placement in garden spaces must be in the back of garden beds or along borders like fences or walls. Soil must stay cool and moist, and some shade will work best. As this plant is highly poisonous, make sure it is kept out of the path of pets and children.
Dig your hole twice the size of the root structure of your plant, making sure that your hole is full of loose dirt and organic materials such as leaves. It is extremely important to wear gloves when handling the plant or the roots. Even the leaves are highly toxic, and the poison can absorb through your skin.
Stake your plants, as they grow quickly and need support in the wet soil conditions.
