A description of Eupatorium album is provided in The Flora of North America.




It is found in sandhills, Longleaf pine-wiregrass savannas, evergreen scrub oak sand ridges, pine flatwoods, old fields, flatwoods, hammocks, seepage slopes, pine-palmetto flatwoods, in woods adjacent to sinkholes, and in well-drained Longleaf pinelands. [1] It is also found in human disturbed areas such as roadsides, areas that have been clear cut, clobbered, bulldozed, and in powerline corridors.[1] It requires open to semi-shaded areas.[1] It is associated with areas that have drying-loamy sand, wet-sandy loam, dry sand, gray-sand loam, dry-sparsely loamy sand soil types.[1] It does well in open canopy areas on longleaf pine habitats and does okay in areas that have been clear cut. [2] It is found in longleaf pine sandhill communities. [3] Associated species include Eupatorium recurvans, E. mikanioides, E. rotundifolium, E. anomalum, E. compositifolium, E. aromaticum, Chamaecrista fasciculata, Sassafras albidum, Pteridium aquilinum, Quercus incana, Q laevis, Aristida beyrichiana, Serenoa repens, Ilex glabra, Rhynchospora, Xyris, Magnolia virginiana, E. rotundifolium, Solidago odora, Liatris gracilis, L. tenuifolia, L. elegans,Sericocarpus tortifolius, Rubus cuneufolius, Andropogon ternarius, Carphephorus corymbosus.[1]


It has been observed flowering from July to November.[1] Kevin Robertson has observed this species flower within three months of burning. KMR

Seed dispersal
