Ecology
Habitat
This species can be found in marshy depressions surrounded by live oak hammocks, pine-oak woodlands, grass and succulent cover, beach hammocks, longleaf pine forests, old fields, along oak scrub edges, and bordering salt marshes.[2] O. simulans has been observed to grow in moist loamy, loose, and silty sands in open areas.[2] This species is "one of the most aggressive pioneers in disturbed areas" such as plowed fire lanes, along roadsides, vacant lots, clear cut pinewoods, and along fence rows.[2] Associated species includes Pinus, Quercus, Papaya, Forestiera, Bumelia, Eugenia, Piscidia, Agave, Yucca, Juniperus, Sabal, Bumelia lanuginosa, Crateagus floridana, Pinus elliottii, Myrica cerifera, Pinus palustris, and Conzya.[2]
