Today’s Quiz Question is actually more a plea for help to identify a roadside plant which caught my eye yesterday. 
It was tall, at least 1.2m, and grew in a large clump. It had the faintest blue flowers.
I thought the leaves might give it away as they were quite distinctive but, Google has let me down on this one.
I am sure it must be common and well known, but not to me!
Any ideas please?

Wild Chickory! It is common but it’s one of my favourite wildflowers nonetheless.
p.s. I just looked it up in my flower guide – I spelled it incorrectly: it’s “Chicory” (Cichorium intybus).
Thank you Dr. Booky, that appears to be absolutely correct! I have never seen it before it was so beautiful I am amazed nobody has hybridised it. It has all the qualities of a good garden plant.
Dear David, I am not sure what the plant is but I have Cichorium Intybus and it has lovely deep powder blue flowers and grows to six feet plus and the basal leaves are 12″ plus and very floppy.
Looks like you are also correct Mr Titchmarsh. Thanks for taking part.
What a lovely plant to have in the garden. Is it a British wildflower or is it cultivated?
