We went to the Metro Gardens a few weeks ago and walked along the boardwalk trail. We happened to pick up this brochure that shows different types of wildflowers and where you can find each of them along the trail between the numbered markers.
While I was not able to take any photos of wildflowers on the trail while pushing a stroller, I do have some from around the neighborhood (Thanks to hubby).
I also found a website where you can put in all the information about wildflowers and it will identify the flower. There is an app that you can download for your phone as well.
