Most roadside wildflowers aren't native to North America so it makes a nice change of pace to point out a few that are actually natives
love, love, love fleabane. Illinois Wildflower resource is great - made me happy to read this:"While the fleabanes (Erigeron spp.) are often dismissed as 'weeds' because of their ubiquitousness during the summer, they are actually rather attractive plants that are beneficial to many small insects that have important roles in the functioning of the ecological system. As pioneer species, fleabanes are also useful in providing early cover for exposed ground, thereby reducing soil erosion."Great work on all the plant i.d. - really appreciate it!
