Frankenia johnstonii
Also called Johnston's Frankenia, Johnston's Sea Heath
Johnston's seaheath is a low, woody subshrub from dry, saline flats in southern Texas and northern Mexico, grown mainly by specialist growers and in conservation settings. It needs full sun, excellent drainage and very little water.
Frankenia johnstonii is a species of flowering plant known by the common name Johnston's seaheath, or Johnston's frankenia. It is native to southern Texas in the United States and northern Nuevo León in Mexico, where there are about 30 occurrences known. The plant was federally listed as an endangered species in the United States in 1984. It was found to be more abundant than previously thought and it was proposed for delisting in 2003.
In 1984 there were only 6 populations known, all on privately owned land, and the plants appeared to be in poor condition and were reproducing slowly. Most plants observed had been trimmed down by grazing cattle, which also appeared to alter the habitat itself. Fewer than 2000 plants were counted and it was placed on the endangered species list of the United States.
