Description
It is an annual and flowers in the fall[1]. It flowers summer to fall[2].
Distribution
It is infrequent in central, north, and west Florida. Found from: West to Mississippi, east to Alabama[1]. Listed as critically imperiled in Alabama and Georgia[3].
Ecology
Habitat
It occurs primarily in well drained sands and loamy sands of pine-oak sandhill communities, sand dunes and interdune hollows (Entisols), and pine flatwoods communities (Spodosols). It thrives in frequently burned areas[4]. It is found in dry, scrub pinelands[1]. It is found in dry pine-oak savannas, sandhills, and mesic bog margins[2]. Found in dry loamy sands, well drained sands, deep coarse sands, and loamy sand areas[4]. A. divaricata is also fund in human disturbed areas such as pine plantations, old fields, and along roadside edges and ditches. It does well in high levels of light.
Associated species: Myrica, Pinus, Quercus, Liatris, Pityopsis, Agalinis pulchella, Agalinis aphylla, Agalinis tenuifolia, Agalinis plukenetii, Quercus laevis, Aristida stricta, Andropogon spp.; Polygonella, Chrysopsis, Haplopappus, Opuntia, Eupatorium, Dicerandra, Trichostema, Liatris gracilis, and others[4].
Fire ecology
It thrives in frequently burned areas; and occurs in areas with extremely xeric conditions (such as sand dunes) which limit competition with other vegetation[4].
Conservation and Management
A. divaricata requires fire or other vegetation-removing disturbance to maintain high light levels in the habitat which also reduces competition. It does not appear to be common in areas with a great deal of soil disturbance, although it occurs along roadsides and ditches[4]. This species is highly threatened by land-use conversion, habitat fragmentation and forest management practices[3].
