Blue or Purple

Me and Mr A had dental check-up appointments this morning in Saffron Walden and then we had coffee and a gluten-free cake in Costa before coming home. We hardly ever visit Saffron Walden except for dental treatment or to visit our friend who lives there. The appointments were first thing and it was fine when we went into the dentist, but raining when we came out; it has rained ever since.

Today's picture is of a blue or purple flower, which is a rockery plant which has yet to be planted in its final place; no idea what it is called!
