Unusual?

I spotted this plant which I don't know as I was leaving Wimpole this afternoon.  I must look it up as I don't recognise it.    It's rather an odd, not a very pretty plant.  But it covers quite a big area of wall.

PS It's called Jerusalem Sage!

2 days to sort out packing etc.  And then we are off!  All being well there should be some good blips.
