| Marshallia graminifolia | |
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. [2] Like all species in the genus Marshallia, it has the common name Barbara's buttons, [3] and is specifically known as grassleaf Barbara's buttons. [1] [4] It has fragrant flowers. [5]
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). [2] [6] [7]
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. [7]
