Name:
Toxicodendron radicans / Heuchera americana - (Dichanthelium depauperatum, Woodsia obtusa) Herbaceous Vegetation
Reference:
Southeastern Ecology Working Gro...
Description:
This association is variable in composition and vegetative cover, but includes a range of dry, basic cliffs of variable geology characterized by the presence of scattered to moderately dense vines and forbs. Characteristic vines, shrubs, and scattered shrubs may include Hydrangea arborescens, Toxicodendron radicans ssp. radicans, Parthenocissus quinquefolia, Philadelphus hirsutus, Philadelphus inodorus, and Cercis canadensis. Characteristic herbaceous species (very variable from occurrence to occurrence) include Heuchera americana, Dichanthelium depauperatum, Woodsia obtusa, Viola triloba (= Viola X palmata var. triloba), Oxalis violacea, Carex sp., Dichanthelium depauperatum, Toxicodendron radicans ssp. radicans, Parietaria pensylvanica, Danthonia spicata, and Dichanthelium dichotomum. The association, as broadly defined, is widespread in the Southern Blue Ridge, Cumberlands and Southern Ridge and Valley, and Interior Low Plateau(?). It is peripheral in the western Piedmont (e.g., the South Mountains?). The exotic Microstegium vimineum may be present.
