A view from above. Note how the flowers spread out.

Note the whorled aspect to the leaves in this photo.
A "grove" of Whorled Asters. They may grow solitary or in colonies like this. These photos were taken in New Brunswick and Nova Scotia in mid-September. In Ontario this Aster only occurs in a small part of far southeastern Ontario, close to Quebec.
