One of the things we have learned after several generations of daffodil breeding with N. viridiflorus in the background is that there can be many shades and colors of green – ranging from yellow-greens to blue-greens and even grey-greens. The flowers illustrated here are currently in bloom in my garden.
There is some difficulty in capturing the exact shade of green with a digital camera. Below are two pictures of the same flower but one is against a black background.
This is the closest for color accuracy. Same flowers as some in the previous post.
