Walking the rail-trail in the Lily Lake area the other day, I couldn’t help notice how quickly the asters are taking over as the dominant wildflowers on the landscape. Already, some of the goldenrods – which still provide most of the colour – are beginning to fade. I was able to identify five species, although there were probably more. One of the best resources for sorting out the asters is Ontariowildflowers.com Knowing at least a few of the common species adds a great deal to any late summer or fall walk.
Heath Aster

Heath Aster (numerous, very small flowers that are packed close together)

New England Aster

New England Aster (rich purple in colour)

Heart-leaved Aster

Heart-leaved Aster (leaves at base are heart-shaped)
