spot the flower

We went to Wisley today. It was really busy -10 coaches in. Apparently they have had 88 coaches booked in this week plus numerous schools. Something to do with the Chelses Flower show

I really didnt know what to choose but with it being flower friday it had to be a flower. So Spot the flower 
The extras are from the garden outside the glasshouse  and not realising the tropical plants  flowered and the other is the field of Aliums.
