Can anyone identify this climber?

[Blueskytoday]

Saw this really nice plant, it was covering a yew hedge almost completely.
Hard to tell on photo but very tiny flowers and little berries

Never seen that before, what part of the country are you in?

Tropaeolum speciosum - the Scottish Flame flower : www.rhs.org.uk/Plants/18460/Tropaeolum-speciosum/Details

Thanks, that's it.
It was in the garden at DAlemain, a historic house and garden.
It's in Lake District near Ullswater,
It looked really amazing covering a huge hedge

Is that shiny blue thing a berry ?

Yes they are berries - it's basically a climbing Nasturtium, but very tricky to grow, liking cool moist conditions (hence it does well in Scotland!)
I tried it once, against a fastigiate golden Yew, but conditions were too warm and dry (I'm in the Southeast).
