Tampa mock vervain

Glandularia tampensis
Plant Botanical Name: 
Glandularia tampensis
Plant Threat Level: 
Endangered

Glandularia tampensis, endemic only to coastal areas of southern Florida, is endangered because of loss of habitat to development and agriculture. Very few populations remain intact in nature, and efforts are being made to protect habitat and to preserve germplasm from these remaining populations. To slow demand for wild-collected plants, some nurseries are propagating Glandularia tampensis. Although not common, it is becoming popular among native plant collectors and enthusiasts of butterfly gardens.
