Marshallia graminifolia is a perennial herb species, endemic to the coastal plains of the Southern United States, where it often grows in bogs and in sunny locations.[1] Like all species in the genus Marshallia, it has the common name Barbara's buttons,[2] and is specifically known as grassleaf Barbara's buttons.[3]
M. graminifolia has two accepted subspecies, M. graminifolia subsp. graminifolia, and M. graminifolia subsp. tenuifolia (commonly known as narrowleaf Barbara's buttons or slim leaf Barbara's buttons).[4][5]
M. graminifolia subsp. tenuifolia grows in moist sandy habitats, such as bogs, wet savannahs and low pine woods in the south-east coastal areas of the United States, from the south coast of Georgia along the gulf coast into east Texas. It has a deep taproot, lavender to white flowers and an achene fruit.[5] The disc shaped flowers are fragrant.[6]
