The native plants listed on this page prefer sun or part sun. You will notice that some of my plants like the Lobelias are mentioned on both the Shade/Part Shade as well as Sun/Part Sun page. This is because I enjoy planting my natives in sections of my yard that may not be ideal, then watching to see how things work out.
My lobelias did fine in full sun. The down side of course is that during the heat of our 2012 summer they required a watchful eye and a full watering can.
