DistributionSouthern Coastal Plain. Known only from Bladen (a powerline) and Brunswick (Green Swamp) counties. Neither population has been seen for over a decade, despite some searching.

Coastal Plain, from southeastern NC to northeastern FL.
AbundanceKnown only from two sites in the state, but both have been searched for in recent years without success. The Brunswick population was last seen in 1980 and the Bladen one in 2004. As a result, the website editors feel that the NCNHP's State Rank of S1 is no longer correct and instead a rank of SH (historical) is more appropriate. This is a State Endangered species, and with a Global Rank of just G2, this is a very rare species across its small range.
HabitatWet Longleaf Pine-Wiregrass savanna; powerline clearing with seepage.

PhenologyFlowering and fruiting late August-October.
IdentificationStems typically grow 1.5-2.5 feet tall, with 1-4 terminal heads that have yellow ray florets and distinctly red-purple disk florets. Helenium brevifolium may have red-purple disk florets, but it blooms in spring. One-flower Honeycomb-head (B. uniflora) is very similar but has yellow disk florets.
