Mystery plant

Visited Tyntesfield NT house with my grandma today (as an aside, highly recommend a trip if you're in/passing through the west country - the kitchen gardens are incredible) and she was very taken by a plant in one of their glass houses. Poor quality picture below (phone camera has a crack in it ). It was in an unheated glasshouse with several soft fruits, climbing up against a wall and covered in huge clusters of blue flowers. 10ft high and very bushy. Sadly no useful label, and the only person around was a new volunteer who very apologeticlly didn't know.

 

Hi 2nd-bassoon ,

It's a Plumbago ( common name Leadwort ) . Probably P. Auriculata .
