Salvia lyrata; Lamiaceae (mint family)
It’s that time of year – the time when the mint family plants start blooming. They’re one of the dominant families in this area. (Last year I saw more in this family than any other except the pea and aster families.)
The second picture is from last year, taken with the iphone; it’s the only half-decent one showing the basal leaves for which the plant is named.
