Answer: Almost any flowering plant will produce seeds, so look for spent flowers (flowers with petals that have recently fallen off). The swollen ovary just below where the petals are (or were) is where you'll find seeds. In your region you might look for wildflowers or even weeds that are about to set seed. Walk through your own garden and pick off a few flowers and dissect them. Pull off the petals and open the ovary. You'll find (in most cases) that there are seeds within the swollen base of the flower. Hope this helps with your project!
