More plants in the aster family are now flowering across Iowa. I have trouble identifying asters, especially the ones with white ray flowers and yellow center disks. The website of the Lady Bird Johnson Wildflower Center at the University of Texas took the pressure off by commenting, “The many small-flowered asters found in eastern North America are often difficult to distinguish from one another, as are many of the large-flowered species.” These descriptions of similar-looking white asters give you a sense of how complicated it can be to identify plants in this group, even for experts.
I enclose below pictures of three or four different aster species you may find blooming in Iowa this month. I believe at least two of them are native; one is an invasive plant from Europe. You don’t necessarily need to explore natural habitats to find these wildflowers. Some are opportunistic enough to grow on low-quality soil in vacant lots or along roadsides. I have a soft spot for the weedy aster species, because unlike, say, wild parsnip, they aren’t hurting anyone.
