Description

A description of Hieracium gronovii is provided in The Flora of North America. Hieracium gronovii is a perennial herbaceous species.

Distribution

Hieracium gronovii is distributed from Massachusetts west to Michigan and Kansas south to central peninsular Florida and Texas.[2] It is also native to the Canadian province of Ontario.[3]

Ecology

Habitat

Generally, H. gronovii can be found in dry forests, sandhills, roadsides, and various woodland margins.[2] It occurs in moist or dry sandy soils, from dry loamy sand to moist sandy peat, dry sand, and moist sandy loam. 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. However, it can also be found in disturbed areas including roadsides, old fields, open annually mowed pineland, power line corridors, and drainage ditches.[4] Additionally, H. gronovii is frequent and abundant in the North Florida Subxeric Sandhills and Clayhill Longleaf Woodlands community types as described in Carr et al. (2010).[5]

This species was shown to decrease in frequency in response to the control of woody species.[6] H. gronovii has shown regrowth in reestablished longleaf pine woodlands that were disturbed by agriculture in South Carolina coastal plain communities, making it an indicator species for post-agricultural woodlands.[7]

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.[4]

Phenology

This species generally flowers from July until November.[2] H. gronovii has been observed flowering in January, February, and July through November, and fruiting in May. [4][8]

Seed dispersal

This species is thought to be dispersed by wind. [9]

Seed bank and germination

Several short-lived perennial forbs also have a seed bank persistent for at least several years.[10] It has been seen to germinate from the seed bank at early successional 1 and 2 year old field sites.[11] As well, fire disturbance has been shown to positively affect seed germination over time.[12]

Fire ecology

Hieracium gronovii has been found in habitats maintained by frequent fire[4] such as the Pebble Hill plantation in north Florida[13] where populations persist through repeated annual burns.[14] Overall, it significantly increases in frequency in response to fire disturbance.[15] This species has been shown to benefit most from summer burn regiments rather than winter or spring burn regiments.[16] As well, it is most frequent in low fire return intervals.[17] Fire disturbance has also been shown to increase the amount of seed germination over a 1 year time span.[12]

Pollination and use by animals

Hieracium gronovii has been observed at the Archbold Biological Station to host leafcutting bees such as Anthidiellum perplexum (family Megachilidae), as well as sweat bees from the family Halictidae such as Augochloropsis sumptuosa, Halictus poeyi, and Lasioglossum coreopsis.[18] Other pollinators of Hieracium gronovii in the Hymenoptera order include Dialictus coreopsis, Halictus ligatus, Anthidium maculifrons, Megachile breuis pseudobrevis, and M. georgica, M. mendica, Ceratina dupla, C. mikmaqi, Augochlora pura, Augochlorella aurata, Agapostemon splendens, Lasioglossum bruneri, L. macoupinense, L. pectorale, L. pilosum, and Heriades variolosus.[19][20] Additionally, this species has been observed to host aphids from the Uroleucon sp. (family Aphididae).[21] H. gronovii is known to be eaten by white-tailed deer.[22]

Conservation, cultivation, and restoration

Hieracium gronovii is listed as possible extirpated by the Maine Department of Conservation, Natural Areas Program. As well, the genus Hieracium is listed as a class C noxious weed for non-native species by the state of Washington.[3] It is also imperiled in Kansas and Ontario.[23]

Cultural use

Medicinally, leaves of H. aculeatus can be bruised and then applied to warts to help eradicate them.[24]
