Description
A description of Hieracium gronovii is provided in The Flora of North America. Hieracium gronovii is a perennial herbaceous species.
Distribution
Ecology
Habitat
H. gronovii occurs in moist or dry sandy soils, from dry loamy sand to moist sandy peat, dry sand, and moist sandy loam (FSU Herbarium). It also seems to prefer light conditions ranging from semi-shade to full sun (FSU Herbarium). This species can occur in a range of native and disturbed habitats. Native habitat includes mixed oak-pine sandhills, pine-scrub oak-palmetto communities, longleaf pine savannas, turkey oak barrens, open mixed hardwood forests, and sandy areas bordering cypress ponds and hillside bogs (FSU Herbarium). However, it can also be found in disturbed areas including roadsides, old fields, open annually mowed pineland, power line corridors, and drainage ditches (FSU Herbarium). Associated species include Quercus margaretta, Pinus palustris, Aristida stricta, Serenoa repens, Crotalaria spectabilis, Lechea mucronata, Desmodium tortuosum, Rubus cuneifolius, Heterotheca subaxillaris, Andropogon virginicus, Paspalum notatum, Solidago altissima, and Eupatorium compositifolium (FSU Herbarium).
Phenology
This species has been observed flowering in July through November, and fruiting in May. [1]
Seed dispersal
According to Kay Kirkman, a plant ecologist, this species disperses by wind. [2]
Seed bank and germination
Several short-lived perennial forbs also have a seed bank persistent for at least several years.[3]
Fire ecology
It has been found in habitats maintained by frequent fire (FSU Herbarium).
Pollination
The following Hymenoptera families and species were observed visiting flowers of Hieracium gronovii at Archbold Biological Station (Deyrup 2015):
Halictidae: Augochloropsis sumptuosa, Halictus poeyi, Lasioglossum coreopsis
Megachilidae: Anthidiellum perplexum
Use by animals
Deyrup observed these bees: Augochloropsis sumptuosa, Dialictus coreopsis, Halictus ligatus, Anthidiellum perplexzcm, Anthidium maculifrons, Megachile breuis pseudobrevis, M. georgica, on H. gronovii.[4]
