AbstractFlowering of Pityopsis graminifolia was stimulated by prescribed fires during the different lightning season in two different Georgia habitats (oak forest and longleaf pine savanna). Populations from northern Georgia were more likely to flower in unburned plots than in southern populations. These differences persisted in common garden studies indicating genetic differentiation between populations. Flowering was also enhanced more by clipping during peak droughts compared to other times of the year.
