Goldenrods can be challenging to learn. However, once you become familiar with the
key identifying features of each species, they don't seem quite as hard to
learn. I got a real kick-start learning Goldenrods in the fall of 2004, during a Hamilton
Naturalists Club walk with Dr. Jim Pringle of the Royal Botanical Gardens

One tip I will give right now to those who are trying to learn
Goldenrods of Ontario. Do not use the Peterson's or Newcombe's field guides to try
to learn these species. You will only end up very confused. Only a portion of
the species featured in these guides actually occur in Ontario. See the
Booklist page for recommended books
about Goldenrods in Ontario.
#1. Here is a list of the common Goldenrods that occur
in Ontario. This is a beginner's list. Get to know all of the species on this
list before moving on to list#2.
#2. The infamous three. These three
species are very similar and very difficult to tell apart. In

#3. These are less common Goldenrods in Ontario. You
should only tackle these as the last step of learning Goldenrods.
#4. Here is a list of Goldenrod species listed in the
Peterson & Newcombe field guides which do NOT occur in Ontario, or are RARE or
VERY RARE in Ontario. In other words, don't bother with these until you're a
master of the others.
