Taxonomic Notes
Synonyms: none
Varieties: R. hirta Linnaeus var. angustifolia (T.V. Moore) Perdue; R. hirta Linnaeus var. hirta; R hirta Linnaeus var. pulcherrima Farwell
Description
R. hirta is an annual/biennial/perennial forb/herb of the Asteraceae family native to North America and Canada and introduced to Alaska.[2]
Distribution
R. hirta is found in all of the United States excluding Nevada and Arizona, all regions of Canada, and Alaska.[2]
Ecology
Habitat
R. hirta proliferates in fields and roadsides.[1] Specimens have been collected from loamy sands at edge od woodland, open woodland, moist roadsides, dry pine woods and fields, moist sandy peat of savannah, longleaf pine wiregrass savanna, saw palmetto flats, old fields, holding ponds, red clay soils, cedar glade, edge of rivers, wet boggy sites, prairie, mixed woods, creek bottoms, slash pine plantation, and other disturbed wet regions.[3] R. hirta is an indicator species for the Clayhill Longleaf Woodlands community type as described in Carr et al. (2010).[4]
R. hirta became absent in response to soil disturbance by agriculture in southwest Georgia. It has shown resistance to regrowth in reestablished savanna habitats that were disturbed by agriculture.[5]
Phenology
R. hirta has been observed to flower from March to November with peak inflorescence in June.[6]
Seed dispersal
This species is thought to be dispersed by gravity.[7]
Fire ecology
R. hirta is not fire resistant, but has medium fire tolerance[2] as shown in populations that have been known to persist through repeated annual burns.[8][9]
Pollination
Bees have been observed visiting this species.[10]
Herbivory and toxicology
Rudbeckia hirta has been observed to host bees from the Andrenidae family such as Andrena miranda, A. rudbeckiae, A. thaspii, A. wilkella and Pseudopanurgus albitarsis, as well as Uroleucon sp. (family Aphididae), members of the Apidae family such as Bombus citrinus, Epeolus bifasciatus, E. canadensis, Melissodes confusa, M. denticulata, M. druriella, M. illata, M. sp., M. subillatus, M. trinodis, Nomada cressonii, Triepeolus donatus, T. lunatus, T. michiganensis and T. remigatus, members of the Halictidae family such as Augochlorella aurata, Halictus confusus, H. ligatus, Lasioglossum sp., L. admirandum, L. cinctipes, L. coreopsis, L. creberrimum, L. hitchensi, L. pectorale, L. perpunctatum, L. versatum and Sphecodes heraclei, members of the Megachilidae family such as Coelioxys alternata, Megachile fidelis, Megachile latimanus, Megachile mendica, Megachile petulans, Megachile policaris, Megachile pugnata, Megachile relativa and Megachile xylocopoides, as well as true bugs such as Apiomerus crassipes (family Reduviidae).[11]
Conservation, cultivation, and restoration
R. hirta is listed as a weedy or invasive species by the Southern Weed Science Society.[2] This species should avoid soil disturbance by agriculture to conserve its presence in pine communities.[5]
