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.
