The goldenrod (Solidago species) is peaking here now. A few whites and purples of other flowers are here and there, but golden yellow is the color to be. I used my Nikkor 70-300mm AF-S VR at 300mm to flatten the perspective. It was taken from a hill overlooking the field. In Aperture I fought with the color a bit. These rich flower colors can be tricky to render as I have mentioned in other posts. I desaturated the bird box moderately to help it stand out. Fortunately desaturated wood looks like weathered wood, so the manipulation looks natural.
I also used the telephoto for this image of a single plant, also to flatten it a bit. It helps capture a large, sprawling plant as a unit. Oh, and remember that goldenrod is not the source of your allergies. Ragweed is, and ragweed has very bland, green flowers. Ragweed uses wind to pollinate. Its pollen is small and airborne, right to your sinuses. Goldenrod is pollinated by insects, so it is big, sticky and can only get air when being ferried by a bee. They do grow side-by-side, but goldenrod is an innocent bystander.
