This is a nice high-key background and it makes a great print. There are a huge variety of Astors such as Daisies and Sunflowers. This was a gardener developed variety on display at Van Dusen Garden in Vancouver.
Photography notes:
The original picture was oriented vertically, as seen on the right, but the lighting is such that works well rotated to the horizontal. The background images are also cropped to hide the edges of the flower.
