|Ethnobotany:||The name porterweed is a reference to reported medicinal uses. A foaming, porter-like brew, much like beer, is made from at least one species in the Bahamas. The drink is used for fever, for "the cooling of the blood," as a wash for skin irritations, to relieve constipation, and for worms in children. Whether it works or not is open to conjecture. Other local names include "snakeweed," "rat's tail" and "vervain." The generic name is taken from the Greek stachys, meaning "spike," and tarphys, meaning "thick," referring to the thickened flowerspike typical of the genus.

|General Comments:||This species can be distinguished from related non-natives by its trailing stems and lance-shaped leaves.|
Stachytarpheta urticifolia, commonly sold by non-native nurseries, is native to tropical Asia. It has an erect growth habit.
Records of this species in Osceola and Wakulla Counties appear related to plants naturalized from plantings. The recorded specimens from Hillsborough County are from Egmont Key, which was long occupied by military people, including families with gardens.
