Jennifer, if you're going on nature walks & collecting seed then likely you are collecting seeds from native plants. Many of those can be ID'd. I found several sites that you can use for reference: http://www.ontariowildflowers....
And again I will mention our plant ID forum. http://garden.org/forums/view/...
We have some people who are super at ID'ing plants so give them a shot at ones you don't know.
I am a strong believer in the simple fact is that what matters in this life is how we treat others. I think that's what living is all about. Not what I've done in my life but how I've treated others. ~~ Sharon Brown
