Eriogonum gypsophilum
Also called Gypsum Wild Buckwheat
A rare, low perennial wild buckwheat that grows only on gypsum rock and gypsum soils in southeastern New Mexico. It spreads mainly by rhizomes, so keep it on gypsum-rich, very well-drained ground.
Eriogonum gypsophilum is a rare species of wild buckwheat known by the common names Seven River Hills buckwheat and gypsum wild buckwheat. It is endemic to the state of New Mexico in the United States, where it is known from only three sites in Eddy County. It is limited to a specific type of soil which is high in gypsum. The plant has been federally listed as a threatened species of the United States since 1981.
This rare plant can be found at three locations in Eddy County, New Mexico: the Seven River Hills, the Black River, and the Ben Slaughter Draw, a small, sloping valley. The plant only grows on gypsum substrates, including outcrops of gypsum rock and areas with gypsum soils. There are few other plants in this barren, rocky habitat, except for other gypsophiles. Plants that grow with the buckwheat on this nearly pure gypsum substrate include Tiquilia hispidissima, Mentzelia humilis, and Anulocaulis leiosolenus. This area is within the Chihuahuan Desert and surrounding habitat includes creosote scrub.
