Largest foxglove.

So I have finally managed to get some foxgloves to grow in my garden (no idea why they've not found their own way here). Here is a picture of one particularly large specimen and I was wondering if anyone has a larger one anywhere. I haven't measured it but I'm 6'5" and standing next to it this is up to the top of my forehead so probably 6'3 minimum. The rest are a much more standard height.
