Plant description
This stately monkshood produces erect spikes of hooded, violet-blue flowers in mid and late summer above deeply divided, dark green leaves.
Although it will tolerate some sun, it is perfect for the back of a shady border, where it needs little attention.
The stems seldom need staking and, since all parts of the plant are highly poisonous, pests tend to leave them well alone.
Combine with Hylotelephium 'Herbstfreude', and Pennisetum 'Hameln' for a dramatic, contemporary trio.

How to care for Aconitum napellus:
Prepare an extra deep planting hole at least 45cm (18in) deep, adding well-rotted organic matter to prevent the soil from drying out in summer.
Always wear gloves when working with monkshood since all parts of the plant are poisonous and a potential skin irritant.
Cut the flowering stem to within 15cm of the ground in the autumn to prevent it self seeding.

Cottage garden
The traditional cottage garden was an intensive, yet carefree mixture of fruit, vegetables, herbs and flowers all crowded into a tiny space. Today, this informal charm can be recreated using modern varieties that largely take care of themselves around an
