Aconitums have a few common names such as monkshood,wolfsbane or devils helmet.They are grown for late colour, mainly blue, and where a tall perennial fits the bill. There are a few shorter growing forms and different colours including a climbing variety. The flowers are the unusual feature looking like a monks hood and are born up tall towers similar to foxgloves. Quite attractive green lobed leaves that unfortunately by the time the flowers open look a bit passed their best. When planted towards the back of the border these can be hidden nicely by some lower growing partners. They are tough plants which grow well in all soils and sun or partial shade. They grow from bulbous roots which along with the leaves are quite poisonous and should be handled with gloves.The root can be cut up and used to reproduce new plants in winter if you get a growing tip above it.
