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. [1] It also seems to prefer light conditions ranging from semi-shade to full sun. [1] 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. [1] However, it can also be found in disturbed areas including roadsides, old fields, open annually mowed pineland, power line corridors, and drainage ditches. [1] 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.[1]

Phenology

H. gronovii has been observed flowering in January, February, and July through November, and fruiting in May. [1][2]

Seed dispersal

This species is thought to be dispersed by wind. [3]

Seed bank and germination

Several short-lived perennial forbs also have a seed bank persistent for at least several years.[4]

Fire ecology

It has been found in habitats maintained by frequent fire.[1]

Pollination

The following Hymenoptera families and species were observed visiting flowers of Hieracium gronovii at Archbold Biological Station. [5]

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.[6]
