Here's blue curls again, more typical of the genus that includes today's false pennyroyal. This one is Trichostema dichotomum. These flowers are close to a half inch.
Today on Portraits of Wildflowers (https://portraitsofwildflowers.wordpress.com/) Steve Schwartzman mentioned the USPS(United States Photographic Service), and the motto about not being stayed from their rounds. Good one, Steve! He reminded me of a previous visit to the false pennyroyal site. This is the only place in Michigan I've ever encountered chiggerrrrs. I hadn't realized the crotch of those old jeans was worn through. I really hate those bugs!
