Grecian Windflower (botanical name: Anemone blanda)
This daisy-like flower is approximately 1 to 2 inches in diameter and comes in shades of lavender, pink, white or blue, although they are all lavender in my garden.
Here you see a bud just about ready to open...
and here you see one even closer to blooming. Most years Grecian windflowers bloom in my gardens for five or six weeks.
