Brighter day

The sun has come out after a rainy start.  Apologies for another flower blip, but I liked this self-seeded sunflower which has appeared in my garden (6 have popped up out of nowhere!).  I love the "sunny" flowerhead, but concentrated on the intricate centre of the flower.  
My extra is one of the flowers I bought at Harlow Carr, - it has just started to flower, but I cannot remember what it is called!
