The greatest number and diversity of species is found in the disturbed areas such as mowed roadsides and drainage ditches. In the latter one finds herbs such as Callitriche heterophylla, Centella asiatica, Rhynchospora corniculata; Sagittaria graminea, Polygonum punctatum and several species of Hydrocotyle, Ludwigia and Proserpinaca. On the moist slopes of these ditches are Bacopa monnieri, Cyperus surinamensis, Dichromena colorata, Drosera leucantha, Tradescantia virginiana, Utricularia subulata and several species of Eleocharis, Hypericum, Juncus and Xyris. On drier sunny roadsides are herbs such as bulbous Allium canadense, spreading Asclepias humistrata, Daucus pusillus, Helenium amarum, and Plantago virginiana. The lawns and other open grassy areas are similar in species composition to the roadside areas. Weedy species there include Portulaca pilosa, Geranium carolanianum, dichondra carolinensis, Cerastium glomeratum Cenchrus echinatus and Poa annua.
