Roadside Emergency

Technically it wasn't a REAL emergency, but I did stop on the way home from church on Sunday to take a picture of this prairie flower.

I've been watching it bloom everyday on the way to and from school and wanted to stop, but not wanting to get sideswiped. Not much truck traffic on Sundays, so I pulled over.  It was in the bright noon time sun, so it looks washed out.

Beyond the fence post is the crunchy pasture that is so dry. I'll need to do some research on this plant. There's this large one and one other smaller one down the road. { update: I've been searching wildflower data bases and found what I think may be a match: Cleome serrulata.}They are not like the sand lilies that are everywhere earlier in the summer. It  must have a deep tap root to survive like my bush morning glory.
