I conducted a survey in the piedmont and coastal plain of South Carolina during 2000-2003 that documented 23 population sites in eleven counties for the recently described Rhododendron eastmanii (May-white azalea). Populations were typically located on north-facing slopes of rich, mature forests above streams dominated by oaks, hickories, and other deciduous trees. Soils had a loamy sand to sandy loam texture and were circumneutral to slightly acidic. This species is more widespread than originally thought, and botanists in Georgia and North Carolina should look for the presence of this species.
