A fairly large flowering plant, I suspect it is an 'escape' of some sort though no gardens nearby:

Himalayan Balsam I believe

Thanks Cheryl, first time I've seen this invasive 'weed' however attractive it is.

Go back nest year and the place will be smothered in the stuff to the detriment of other plants. It's a very aggressive non-native that successfully seeds everywhere

Landowners should be cutting it down before it sets seed.. it's an annual, so by cutting it before the seeds are set it can be controlled!
