Stachytarpheta cayennensis can be a noxious weed and is listed as a Category II non-native invasive plant by the Florida Exotic Pest Plant Council. This variety of Blue Porterweed is an upright perennial growing to 3 feet in height with branching stems, a woody base and long tap root. The dark purplish-blue flowers last just one day and are attractive to Butterflies.
