Aconitum 'Stainless Steel'

Monk's hood


Aconitum 'Stainless Steel' is a tall, upright perennial with deeply divided grey-green leaves and spires of hooded, steel-blue flowers in summer. It does best in partial shade, although it will cope with full sun provided the soil does not dry out in summer. Great for lightening up shady woodland planting schemes.

N.B: Always wear gloves when working with Aconitums, as all parts of the plant are poisonous and may also cause skin irritation.
