|Natural range of Quercus laurifolia from USDA NRCS Plants Database.|
Common names: Laurel oak, Swamp laurel oak, Diamond oak
Synonym: Quercus obtusa (Willdenow) Ashe
A description of Quercus laurifolia is provided in The Flora of North America.
Q. laurifolia has been found in longleaf pine-turkey oak sand ridges, sand pine scrub, salt marsh shorelines, sand dunes, areas with sandy-peaty soil, live oak groves, pond shorelines, pine flatwoods, and scrub oak. It is also found in disturbed areas including disturbed oak pine Ilex woods, near boat landings, and along roadsides.
Associated species: Q. geminata, Q. chapmanii, Q. laevis, Pinus clausa, Ceratiola ericoides, Osmanthus, Q. virginiana, Q. nigra , and Q. myrtifolia.
Q. laurifolia has been observed to flower from March to May, and in August and September.
This species is thought to be dispersed by gravity.
Herbivory and toxicology
Quercus laurifolia has been observed at the Archbold Biological Station to host bees such as Apis mellifera (family Apidae) and Colletes brimleyi (family Colletidae). Additionally, this species has been observed to host planthoppers such as Alebra sp. (family Cicadellidae) and members of the Flatidae family such as Metcalfa pruinosa and Ormenoides venusta, true bugs such as Cedusa sp. (family Derbidae), and treehoppers from the Membracidae family such as Archasia belfragei, Cyrtolobus fuliginosus, Cyrtolobus ovatus, Cyrtolobus tuberosus, Ophiderma definita, Ophiderma pubescens, and Smilia camelus. Q. laurifolia frequently produces large crops of acorns that are an important food source for raccoons, white-tailed deer, squirrels, wild turkeys, ducks, quail, and smaller birds and rodents..
Conservation, cultivation, and restoration
Bark was mixed with other oak species bark by the Choctaw to create dyes and paints.
