Bergamot (Monarda fistulosa) is currently in bloom. It's also known as Bee Balm and is a good source of nectar for bees and butterflies. I think of it as a tallgrass prairie wildflower but its native range is much wider.
I teach economics at Kalamazoo College. My wife is also an economist. We were on sabbatical in Europe for the 2014-15 academic year. (Salamanca, Spain, followed by Oxford, UK.) We were in Uruguay for the 2006-7 academic year.
