I bet your impressed with my knowledge of this flowers name, commonly know as Livingstone Daisy. Oh alright I admit, I had to ask a friend who is fantastic with know the names of flowers etc.
Could be greeted with the famous saying, "Livingstone I presume", as Henry Morton Stanley greeted Dr. Livingstone in Africa.
Found this again in my Sisters garden just outside her conservatory, she tells me it opens in the morning and closes at night, clever flower.

Beautiful! This is like our stokesia, a purple flower which blooms during the day and closes at night. We look forward to it coming up each early summer but now its gone. A delightful summer friend.
