Buddleia, probably

Went to Gateshead, worked, noticed a small bush growing out of a chimney pot, worked, came back, worked.

I tried to take a photo of the lady Northumberlandia from the train home, since she's usually a reliable blip, but a trackside bush got in the way. They seem to be doing some works that involve raising an earthern rampart between herself and the railway line - I do hope they're not going to spoil the view. But there are some great shots of her from various angles on Blip now.

Just looked at the bush large to try to identify it and realised that there's a small bird sitting on it, top right!
