Hardy Tropicals UK

My sister purchased this plant from a rare plant fair last year and is wanting to buy some more but doesn't remember the name of it.
She has asked me what it is and is REALLY loving the fact that she has asked me the name of a plant and for once, I don't have a clue!!
I'm having to admit defeat and even though I recognise it, I can't for the life of me say what it is!

Help please!

Incarvillea delavayi. I've got one and it's not at all painful

BINGO!!

Thanks Greville
I'll have to say to her that during the night I had a dream that I was planting them and read the label in the pot. Jotted it down on waking in the morning! Subconsciously remembering!

Although she does look in on this site sometimes so I'd better own up!

Thanks again!
