Baton Rouge is located in Zone 8 for plants as i found out.  I found several links for shade plants that I think will help everyone.

 

This first link is actually from one of our rival’s Mississippi State,

These next links aren’t as organized as the MSU link but do provide more options,

This last link has plants that are suitable for Deep Shade,

I know some people were interested in plants for Phytoremediation.  Phytoremediation is the use of certain plants to clean up soil, sediment, and water contaminated with metals and/or organic contaminants.  This first link that I found gives a good overview about the subject and has charts that can be useful in understanding how Phytoremdiation is used and its advantages/disadvantages,

This link gives plant types, what types of contaminants it cleans up, what phytoremediation process it uses, and comments from this websites study, http://www.superorg.net/archive/proposal/plant%20species%20phyto.pdf
