Mystery Native Plant

14 years ago

Can anyone identify this plant? It appears to be an herbaceous annual. On May 18, 2012 it was abundant throughout Fort Ridgely State Park, in south-central Minnesota.

The plant is 18" to 30" in height, but has not yet reached maturity. The leaves are opposite with bluntly toothed margins. The stem is hairless and is covered with whitish, waxy bloom (glaucous). The area where it was photographed is moderately moist.
