Wildflower ID please

Whilst out walking the dog the other day, I spotted the below growing beside a lake - the flower looks sort of like a cross between a foxglove and a snapdragon to my eye; any idea what it is?

 

Thanks Zigs - It was right beside the water at Virginia Water, which a bit of Googling suggests is a fairly common environment for them. Pretty thing.

 

The lake itself, and the surrounding park at Virginia Water is manmade, created back in the 1750's (approx), and there is loads of stuff that has been brought in from other countries mostly as gifts from the nobility of those countries - wouldn't be a bit surprised if the initial seeds didn't make their way in along with a load of stones or sculptures.

 

Its a lovely place to spend a day - not an awful lot going on, but that is the appeal of it to me, and it is big enough that you can lose yourself there for the day.

Advisable to take a picnic though, as the eateries on site charge have mortgage applications on their counters (or they should have with their prices!);

 

Are you going to grow it near a pond or something?

Although the flowers aren't abundant, they are quite striking, mainly because of the way they hang underneath the foliage.

 

Good luck with it - be nice to see a photo of it once you get it established.
