Silphium albiflorum

Silphium albiflorum, commonly known as white rosinweed,[1] is a species of flowering plant in the family Asteraceae. It is native to the United States, where it is endemic to the state of Texas.[2] Its natural habitat is in open, calcareous prairies.[3][4]

It is a tall perennial with rigid, deeply divided leaves. It produces heads of white flowers in late spring through mid-summer.[3] It is a slow growing, but extremely long-lived plant.[5]

Due to its narrow habitat requirements and low population recruitment, it is considered to be a highly conservative species. It fares poorly in areas of suburban development, and faces significant threats in parts of its range.[6]
