The rose and cognac tributes of an anonymous man in black - dubbed the "Poe Toaster" - are thought to date to at least the 1940s. Notes left with the tributes indicate the tradition passed to a new generation in the 1990s.
But the visitor hasn't appeared since 2009 and was a no-show the last two years. Last year's vigil attracted impostors, including a man who arrived in a limo.
Poe House and Museum Curator Jeff Jerome says he'll wait one last time overnight Wednesday before calling an end to the tradition.
