Description

Also known as coastal bedstraw, G. hispidulum is a native perennial forb that is a member of the Rubiaceae family. [1]

Distribution

G. hispidulum is native to the southeast United States, ranging sparsely from east Louisiana and following the coastlines to Maryland and Delaware. [1]

Ecology

Habitat

G. hispidulum grows in maritime forests, dry sandy forests, and sandhills. [2] It is mostly found in well-drained soils along the Gulf coastal plain. [3] It is associated with the longleaf pine ecosystem.[4] While it is present in these natural communities, G. hispidulum is only seen occasionally and not as frequent. [5] It can be found in native cover communities as well as disturbed sites. [6] More specifically, habitats of G. hispidulum can range from loamy and drying sands in pine-wiregrass or oak-hickory woodlands, in general disturbed sites like open areas and crevices along roads, sand pine scrub, sand dunes and interdunal sandy flats, and various hammocks. [7] As well, it is considered an indicator species of the north Florida longleaf woodlands habitat.[8]

Associated species - Salvia lyrata, Elytraria caroliniensis, Dyschoriste humistrata, and Sanicula canadensis. [9]

Galium hispidulum is an indicator species for the North Florida Longleaf Woodlands community type as described in Carr et al. (2010).[10]

Phenology

G. hispidulum has been observed to flower from April until August, and in the months of October and December. [11] G. hispidulum has been seen to develop fruit during June through December. [7]

Seed dispersal

Seeds of G. hispidulum are primarily dispersed through animal consumption. [6]

Seed bank and germination

This species was not found to persist as a component of the seed bank even though it was present as herbaceous cover in southwest Georgia.[12]

Fire ecology

It commonly grows in habitats that are considered fire-dependent.[8] The species has been seen to be associated with a low rate of fire dependence, where the community is not burned as often as other normal sites. [13] As well, it can also be found in areas that are fire-excluded.[14]

Herbivory and toxicology

It consists of approximately 2-5% of the diet for various large mammals.[15]

Conservation, cultivation, and restoration

This plant is listed as endangered by the states of Maryland and New Jersey and their Department of Environmental Protection. [1]

Cultural use

This species can be used to make colored dyes, ranging in color from yellow to a rich red depending on which portion of the plant is used.[16]
