Plants were about 3 inches in height.
Windy conditions at time of photo.
Maybe a Triteleia?
Height of plant is about 8 inches.
If you magnify photo, you can see hairs on the axis of the stem and portions of the petals.
I'm leaning toward Delphinium hesperium, but could certainly use an expert's opinion.
Dang this is pretty...
Wading in Crissy Field Marsh. Sorry for the bad cell phone picture :(
