Description

A description of Eupatorium album is provided in The Flora of North America. Although the fruit is usually referred to as an achene, it is technically a cypsela.[1]

Distribution

Eupatorium album can be found from Connecticut, New York, Ohio, and Tennessee south to Florida and Louisiana.[2]

Ecology

Habitat

This species can generally be found in various dry woodlands.[2] 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. It is also found in human disturbed areas such as roadsides, areas that have been clear cut, clobbered, bulldozed, and in powerline corridors. It requires open to semi-shaded areas. It is associated with areas that have drying-loamy sand, wet-sandy loam, dry sand, gray-sand loam, dry-sparsely loamy sand soil types.[3] It does well in open canopy areas on longleaf pine habitats and does okay in areas that have been clear cut. [4] It is found in longleaf pine sandhill communities. [5]

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.[3]

Phenology

Generally, E. album flowers from late June until September.[2] It has been observed flowering from July to November with peak inflorescence in July.[3][6] Kevin Robertson has observed this species flower within three months of burning. KMR

Seed dispersal

This species is thought to be dispersed by wind. [7]

Fire ecology

It flowers within three months of burning in the early spring to early summer. KMR

Conservation and management

E. album is listed as endangered by the Connecticut Department of Environmental Protection and by the Indiana Department of Natural Resources, Division of Nature Preserves. It is also listed as threatened by the Ohio Department of Natural Resources, Division of Natural Areas and Preserves, and listed as extirpated by the Pennsylvania Department of Conservation and Natural Resources.[8]
