I googled and the first image was another picture of a mixture of red and white..
The photographer might have carefully chosen a spot where only one showed with the reds..It’s an oldie but a favorite of mine..I do recycle!
I love poppies - their stems are so tall and graceful and the blooms are so bright and colorful. I am partial to the red ones. I have a beautiful sofa pillow with red poppies on it, and I painted that same design on a white porcelain umbrella stand. :)
