We moved to our new home ten months ago and so this is the first season for us with our new garden. it is a Victorian former railway house in Lincolnshire. This flower has just come up on a verge and I have no idea what it is. The leaves resemble a delphinium and the colour is a beautiful violet blue. It is about 1 metre tall. However, the flowers have a hooded appearance at the top the like of which I have never seen! The buds look like beans. Anybody out there who can throw some light on this for me please!
