Nuttall's Sunflower / Helianthus nuttallii

A photo form my archives. I finally got out with friends for an almost three-hour botany walk in the afternoon of 11 August 2015, at Griffith Woods. There were certain "target" plants on the list, including three species of wild Gentian and one species of Orchid (Rattlesnake Plantain). We had success with all four, which made for a great outing. There was also a patch of these beautiful wild Sunflowers, which I always enjoy seeing year after year. They are sometimes called Common Tall Sunflower, as well as Nuttall's Sunflower.

So many of the plants were finished already, after blooming two weeks early this year. Whenever I see Asters, I know that our flowering season is coming to an end, which is always depressing. The growing season in Alberta is so very short.
