The prairie is in bloom! So, it’s the perfect time to spot Iowa wildflowers on your outdoor adventures. You can find these beauties while hiking and biking (and even along roadsides). But, of course, visiting local prairies is an excellent way to see Iowa wildflowers.
Restored prairies are ideal for an Iowa wildflowers scavenger hunt! And, if you want to go out and see them in bloom, we got you covered. Below are ten common prairie wildflowers to see in the summertime in Iowa.
First, Fun Facts
