AbundanceVery rare, known from just a handful of sites. The NCNHP database lists only five records, all still extant. This is a State Endangered species.
HabitatWet Longleaf Pine-Wiregrass savannas and flatwoods, pitcher-plant seepages, roadside ditches. The habitats are essentially the same as for the Southeastern Sneezeweed (H. pinnatifidum).

PhenologyFlowering and fruiting April-May.
IdentificationThree of our species of sneezeweed bloom in mid-late spring, have well-developed basal leaves but few and small stem leaves, and can be testy to tell apart without attention to details. Leaves of Southeastern Sneezeweed are not decurrent on the stem or at most 5 mm long (there is no continuation of leaf tissue as a "wing" down the stem). Both Savanna Sneezeweed and Shortleaf Sneezeweed (H. brevifolium) are conspicuously winged. The latter differs in its glabrate stem just below the head (vs. densely pubescent). As with Southeastern Sneezeweed, this species has just one or two flowering heads, but each is large (2 inches across). In fact, at a distance these two species look nearly identical and can occur in similar habitats.
