Physostegia correllii Commonly known as Correll's False Dragonhead Correll's false dragonhead is an endangered, water-loving perennial that once occurred in several areas in Texas, Louisiana, and Mexico but is now restricted to two or three sites in Louisiana and one possible site in Travis County, Texas (Poole 2001; Singhurst 2001). Its current status in Coahuila, Nuevo Leon and Sonora, Mexico is unknown. Physostegia correllii bears lavender snapdragon-like flowers in July on tall slender stalks that can reach 7' tall, but more often only grow to about 4' tall. Historically these plants occurred in wetland habitats of the Gulf Coastal region of TX and LA and inland into TX and Mexico. The remaining populations occur in many diverse, unstable wetland habitats: stream sides, roadside ditches and irrigation canals. Spreads by rhizomes. Can thrive in average garden conditions with moist to wet soils.
