A more compact specimen.
Close-up view of the flowers.
Am even closer view.

Here is a small stand of Canada Goldenrod. Note the classic shape.
And a field of mostly Canada Goldenrod.
If you come across a large field of goldenrod like this, you probably won't be far off to say it's a field of Canada Goldenrod.
Canada Goldenrod has very numerous leaves all up its stem. This photo shows the upper stem and leaves, where the flower stems branch off.
And here is the middle part of the stem - leaves still very numerous.
Leaves may be toothed ...
...or have entire (untoothed) edges.
One of the key identifying characteristics of Canada Goldenrod is that the flowers are fairly small. Although the flowers in this photo have finished blooming, it still gives an idea of how small they are. Centimetres and millimetres are on the bottom of the ruler; inches (and tenths of inches) are across the top of the ruler.
PLEASE NOTE: A coloured Province or State means this species occurs somewhere in that Province/State.
