Japanese Toad Lily...?

Another day at Durham, and this flower stood out. I gather from Google images it's a Japanese Toad Lily, but that's the limit of my knowledge, on this or most other gardening issues...

Dropped in on the eldest to celebrate her latest trip around the Sun. Then home... packing a bag, getting an early night, early doors to the youngest's. Looks like we made the right choice, weather-wise.
