Blue flower ID please

View attachment 2898 Does anyone have any idea what this plant is. It looks a bit like a delphinium but Im not sure. This pic was taken on 5th October just after it flowered which I think is too late in the year for a Delph.

Thanks

 

Looks like Monkshood (Aconitum sp.) to me =]

 

The light blue one, to the right, looks like a Delph. though :thumb:

I agree with Aesculus that the dark blue one is probably Aconitum (poisonous, so wash hands after handling, although I think it would take a bit to actually kill you!)

 

It might be Aconitum carmichaelii, which tends to flower late in the year.

 

Definitely an Aconite. Mine flower in summer, so it could well be the one Peter mentions.

 

Thanks for the replys everyone. They must have self seeded as we definitely didnt plant them.

 

It's a good plant for late flowering when there is little colour in the garden apart from the yellows of Rudbeckia.
