Description
Common names: Smooth Gerardia; Purple False Foxglove
Is an annual (Hall 1993).
Distribution
Is frequent in all of Florida. Found from west to Texas, north to Massachusetts (Hall 1993).
Ecology
Habitat
Primarily in low, wet, sandy or peaty areas including streamsides and moist depressions within frequently burned pine communities, seepage slopes, fresh water marshes, cypress flats, and hardwood swamps. It also occurs on shallow limerock soils of slash pine rocklands in South Florida, as well as in high, well drained sandhills (Entisols). It occurs primarily in high light conditions, although it can also occur in relatively shaded habitats such as cypress and hardwood swamps (FSU Herbarium). It is tolerant of high densities of grass and sedges such as in pitcher plant bogs and marshes. Its soil tolerance is wide, including peat (Histosols), loams (Ultisols), and deep sands (Entisols and Spodosols). It also can be found alongside roads, bordering flatwoods, powerline corridors, and other disturbed areas (FSU Herbarium). This species does will in high light intensity areas (FSU Herbarium).
Phenology
It flowers from April to November, primarily in October, and fruits from May to November (FSU Herbarium).
Seed dispersal
Seed bank and germination
Agalinis purpurea was absent from the seed bank of ephemeral ponds in Hyannis though they were present as adults. The composition of the seed bank often predicts the future composition of plants after the disturbance of water level drawdown (Neil et al 2009).
Fire ecology
Communities are near fire-dependent communities such as longleaf pine/wiregrass communities (FSU Herbarium).
