On my local walk this afternoon I saw a couple of wild flowers that I couldn't identify, so I brought them home.... yes, yes I know I shouldn't have really. 

I think I've managed to name White Melilot and Lady's Bedstraw, but does anyone know what the pink flowered one is, which is shown more clearly in the extra photo?

Edit:  I think the pink one is Common Centaury (centaurium erythraea)
