Herb-robert

Seen growing in a wall on my way home from the hairdresser's via the bus stop on Church Hill and the pharmacist's to get my latest meds - Lisinopril for high blood pressure. Hope it will do the job without side-effects. 

Herb-robert is a type of cranesbill or geranium, and I realised after looking it up online that all I needed to do was photograph my photograph with my phone and then Apple would tell me what it was.
