Trichostema is a genus of flowering plants in the family Lamiaceae, which are aromatic herbs or subshrubs. These plants are native to North America.[2][3] Most species in this genus are referred to by the common name bluecurls because of their blue to purple flowers and relatively long, curled stamens.[4]
There are 26 species recognized in the genus.[5] These species are divided into 6 sections based on life history, morphology, chromosome number, and genetics.[6][7] Research on Trichostema in Florida in the early 2020s concluded that there were 10 species native to the state (previously there were only three recognized).[8][9] This determination was based on genetic, morphological, ecological, and phenological data.[9]
