Description
It is a perennial (Hall 1993). It is common in all of Florida; flowers from fall to winter (Hall 1993).
Distribution
Ageratina jucunda is endemic to the southeastern United States, only known to occur in Florida and a few counties in Georgia. [1]
Ecology
Habitat
This species is found in a wide variety of habitat types including longleaf pine-saw palmetto, dunes, rocky environments, old fields, ecotone from scrub oak sand ridge to shrub bof, stream banks, and dry flatwoods.[2] This species can be found in grazed, rocky, and open deciduous woodlands as well. It is xeric to dry-mesic habitats, including sand pine scrub and longleaf pine-turkey oak sand ridges. It can also occur along roadsides and in abandoned fields where such habitats used to occur. Ageratina jucunda becomes threatened by habitat loss and fire suppression.[1]. In addition, it is found in sandhills and hammocks (Wunderlin and Hansen 2003). The soils this species prefers is drying loamy sand with sandy, damp, and rich humus soils (FSU Herbarium). This is a resilient species that has been found growing in numerous disturbed areas including behind shopping malls in weedy woods, phosphate quarries in hardwoods, on and alongside paved roads, rocky plantation pastures, hardwood clearings, pine clearings, near grottoes and edges of of field tracks (FSU Herbarium). This species thrives in environments with moderate shade to high light intensity (FSU Herbarium).
Phenology
It is perennial. [3][2] It is been seen flowering in the month of August and October through January and fruiting during August and from October-December (FSU Herbarium).
