A further list of things to consider. For me, I'd skip the water hemlock, horsetail, and poison sumac!:eek:
There are commonly three distinct vegetation layers in a southern shrub-carr community. The most pronounced is the shrub layer, which typically exhibits little stratification or layering, and ranges in height from 1.5 to 5.5 m (5 to 18 ft, average 2.6 m or 8.6 ft). Common species in the shrub layer may include dogwoods (C.amomum,Cornus foemina, andC.sericea), willows (Salix bebbiana,S.discolor,S.exigua,S.petiolaris,S.serissima, andS.eriocephala), winterberry (Ilex verticillata), elderberry (Sambucus canadensis), swamp rose (Rosapalustris), poison sumac (Toxicodendronvernix), smooth highbush blueberry (Vacciniumcorymbosum), American hazelnut (Corylusamericana), black chokeberry (Aroniaprunifolia), and nannyberry (Viburnumlentago). The shrub layer can be dense to patchy depending on the successional state and local site conditions within the community. The second vegetation layer is an intermediate layer of tall herbaceous plants and short shrubs and can include sedges (Carexstricta,C.comosa,C.hystericina, andC.lacustris), water plantain (Alisma subcordatum), swamp milkweed (Asclepias incarnata), bluejoint grass (Calamagrostis canadensis), water hemlock (Cicuta maculata), water horsetail (Equisetum fluviatile), marsh fleabane (Erigeron philadelphicus), common boneset (Eupatorium perfoliatum), rattlesnake grass (Glyceria canadensis), softstem bulrush (Schoenoplectus tabernaemontani), bulrush (Scirpus pendulus), Canada goldenrod (Solidago canadensis), marsh fern (Thelypteris palustris), bog birch (Betula pumila), swamp gooseberry (Ribeshirtellum), meadowsweet (Spiraeaalba), raspberries (Rubus spp.), and shrubby cinquefoil (Dasiphorafruticosa). A third vegetative layer of smaller herbaceous plants may also occur and include species such as bedstraws (Galiumspp.), clearweed (Pilea pumila), northern bugle weed (Lycopus uniflorus), Canada mayflower (Maianthemumcanadense), and marsh bellflower (Campanula aparinoides).
