Hartwrightia floridana
Also called Hartwrightia
Florida hartwrightia is a perennial wildflower, the only species in its genus, native to open pine flatlands of Georgia and Florida, about one metre tall with white to pink or blue fall flowers. It needs wet soil, full sun and periodic fire, and it is threatened mainly by habitat loss.
Hartwrightia is a genus of North American flowering plants in the tribe Eupatorieae of the family Asteraceae. The genus contains a single species, Hartwrightia floridana, native to the US states of Georgia and Florida. The species is sometimes referred to by the common name Florida hartwrightia.
Although superficially similar to some species in Eupatorium, it can be distinguished by having a basal rosette of leaves, flowers of a different shape, and the fruit which lacks the parachute-like pappus found in Eupatorium. The plant is about one meter tall. It flowers in the fall and the flowers are white to pink or blue.
Hartwrightia floridana is a herbaceous perennial which grows in the southeastern United States (Georgia and Florida). It is found in open areas, for example in pine flatlands, but is not tolerant of grazing or solid forest cover. It seems to do better in the presence of regular fires. It is considered threatened and the biggest threat is loss of habitat. It requires wet soil, and is sensitive to hydrological changes. The seed is a sticky achene without the large pappus which would suggest wind dispersal, so it is presumed to be transmitted by animals.
