Index of all Iowa wildflower Wednesdays

Bleeding Heartland’s weekly wildflower series has grown far beyond what I envisioned when I published the first Iowa wildflower Wednesday in March 2012. The search for material has taken me to many parks and nature preserves I’d never explored and connected me to some incredible photographers and naturalists, including Eileen Miller, Leland Searles, and Marla Mertz.

Many readers have told me the wildflower posts are among their favorites at the site. For a long time I’ve been meaning to collect all of the links in one place.

After the jump you’ll find the common and scientific names of nearly 150 species featured here so far. The date next to each plant’s name links to a post with multiple photographs. I would not have been able to identify most of these plants five years ago. Before my son’s interest in Jack-in-the-pulpits inspired me to start learning more about native plants in 2009, I could not have identified even a dozen of them.

I will continue to update this index once Iowa wildflower Wednesday returns during the spring of 2017.
