Silphium albiflorum

Silphium albiflorum, commonly known as white rosinweed, is a species of flowering plant in the family Asteraceae. It is native to the United States and is endemic to Texas. Its natural habitat is in open, calcareous prairies.

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

Due to its narrow habitat requirements and low population recruitment, it is considered a highly conservative species. It needs to improve in suburban development areas and faces significant threats in parts of its range.
