Verbena simplex B. S. Walters

Plants on limestone pavements (alvars) at Drummond Island and on thin soil over limestone in Monroe Co. are presumably native; as also plants on hjillside prairies in Lenawee Co., where collected as early as 1838 by the First Furvey. Elsewhere in the state, collections from sandy fields, disturbed places, and railroads may at least in part be adventive.

This blue-flowered species has spikes almost as slender and remotely flowered as in the white-flowered V. urticifolia, which has broad leaf blades and distinct petioles.
