Until I moved to Kalamazoo, I didn't know this eye-catching wildflower. When I first saw it, I thought it was an escaped garden flower, since I had never seen it living in western New York or in Wisconsin. Much later, I read that it isn't native to those states. (See this USDA distribution map). Even in Michigan, these plants aren't widespread, occurring mainly in the western counties. They are beautiful.
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.
