Retention Area Plantings

"Government studies have shown that up to 70% of pollution in aquifers, rivers. lakes and coastal areas is carried there by storm-water runoff."  Shaw Nature Reserve Native Landscaping Manual

 
A few of the benefits of retention area plantings are improved water quality, reduced property damage due to erosion, and increased habitat value.

Native grasses for the upper slope include:
Andropogon gerardi
Bouteloua curtipendula
Bouteloua gracilis
Panicum
Schizachyrium
Spartina pectinata
Sporobolus heterolepis

Add color to the upper slope and transition zone with:
Aster
Echinacea
Iris
Phlox
Rudbeckia
Solidago



In areas that stay wet for longer periods of time, there are many plants we recommend: 

Aronia
Calycanthus floridus
Clethra
Hamamelis
Hibiscus (hardy perennial)
Ilex verticillata
Itea virginica
Myrica pennsylvanica
Rhamnus
Salix
Symphoricarpos




Trees that handle wet soil:


 

Betula
Liquidambar
Liriodendron
Magnolia virginiana
Metasequoia
Nyssa
Populus
Quercus bicolor
Salix
Taxodium
Ulmus
