The flare holder includes a lower portion that is attachable to the upright support structure and an ash receptacle that is pivoted at one end to the lower portion. The ash receptacle is can be pivoted up and over the top of the support structure from a stowed position wherein it is suspended from the pivot to an operative position located between 180° and 270° from the stowed position. In an operative position, the flare holder supports a flare at an upward inclination wherein the ash receptacle has an end portion extending outwardly from the pivot and disposed to receive ashes falling from the lit end of the flare.
