I spend a lot of time photographing flowers and when I get mindful enough I look with an unprejudiced eye at local weeds and invasive species. But I have seldom paid any attention to grasses. One reason is their lack of colorful flowers. Another is that those long slender stems are so sensitive to the slightest breeze that they are very difficult to photograph. Grasses have been around for a long time - traces of them have been found in fossilized dinosaur dung. While they are generally pretty inconspicuous they are an important plant family with about 3,500 different species. Click HERE to read what Wikipedia has to say about grasses.
