September Wild Flowers

Thought some of you might be interested in my September Wild Flower letter to my regular wild flower group. Here is part of the letter:

Just taking a couple of minutes away from art show preparations to write this September, already, wild flower list. As I have said other years, many people stop looking for wild flowers when summer is winding down but the flowers do continue and there are some plants that do not start blooming until September. Presently, I have 314 species listed for September. About 20 of those have not started to bloom yet and then there are the spring flowers that sometimes bloom again in the fall. Violets, Honeysuckles, and Dogwoods are three groups that come to mind as spring flowers that bloom again in the fall sometimes.

Following is a list of wild or naturalized flower species that have been found blooming in the Hamilton, Ontario area in September. As usual the * means that the flowers are NOT native to our area. (I see that I am not up to date with all the Latin name changes for the Asters. Sorry 'bout that.)
