the stems are green in the main but red around where the leaves join.
I wouldn't put too much importance on the red, plants grown drier and in the sun will be redder that those grown wetter in the shade. Mine have too much shade now.
There'll probably be more ID people around later on, see what they think.
You're right about the willowherb, different flower shape
