Gratiola quartermaniae
Also called Limestone hedge-hyssop, Quarterman's Hedge Hyssop
A small annual wildflower of seasonally wet, flat limestone outcrops, cedar glades and alvars in eastern North America. It is a rare, scattered native that needs shallow standing water in spring, so it is not a garden plant to grow.
Gratiola quartermaniae, commonly known as the Quarterman's hedge-hyssop or limestone hedge-hyssop, is a species of flowering plant in the plantain family. It is native to eastern North America.
This species has a highly fragmented range. It is most common in the Interior Low Plateaus of Alabama and Tennessee. There are disjunct populations in the Edwards Plateau of Texas, northern Illinois, the Pennyroyal Plain of Kentucky, and to southern Ontario. In each of these wide-ranging locations it is found on areas of pooling water over flat limestone outcrops, in habitats such as cedar glades and alvars. It is likely that this newly described species is more widespread than is currently realized. Due to its highly scattered range and restricted habitat, as well as the threat of habitat destruction in middle Tennessee, this species is considered vulnerable.
