September probably has the highest flower count here: if you were to count each individual aster, lobelia, etc.? Hundreds of thousands easily.  Spring and fall are the two growing seasons for New England, summer is survival against the heat and winter is survival against the cold.

The white wood aster, by the way, (which is in this photo) actually is fragrant: a very subtle floral scent on a good dry day…at least when one is standing in a patch several hundred feet square!
