Discovered in 1765 by the American botanists John and William Bartram. This species has not been seen in the wild since 1803. Originally occurring along the banks of Alatahama River in McIntosh County on the Coastal Plain of Georgia, the only known colony occurred in acidic bogs at the heads of sand-hill branches and was thought to have been brought to extinction largely through overcollection by nurserymen. Numerous expeditions to relocate the plant have failed. It is now a popular garden plant.

Franklinia alatamaha Known naturally only from a single site along the Altamaha River in coastal Georgia, where first noted by the Bartrams in 1765, but apparently extirpated from its natural habitat since 1790 (cf. Wherry, 1928; Harper & Leeds, 1937), or possibly 1803. Nevertheless, long maintained in cultivation, using stock apparently all propagated from a single tree grown by Bartram in Philadelphia. Now widely available commercially, and frequently planted in the northeastern United States. Numerous searches of the type locality and similar areas nearby, over about two centuries, have failed to relocate this plant in the wild. Threats: Subsequent burning and clearing of land during early settlement may have led to extirpation of Franklinia from its only known natural occurrence (Wherry, 1928). Severe flooding following land clearing (perhaps the 1796 flood) may have also been a factor, although less likely to have affected the slightly elevated sand-hill bogs considered the most likely habitat (Harper and Leeds, 1937). Horticultural collecting may have placed additional stress on the occurrence, but is not considered likely to have been the sole cause of this species' extirpation from its only known natural occurrence.

Franklinia is a strikingly beautiful tree and so the Bartrams began to plant wild trees in their garden in the 1770s, Later the descendents of the Bartram trees have survived in Parks, Gardens, and Botanical gardens all over the world.
