Rain Garden Plants Zone 8a

Question

I need some rain garden plant suggestions for zone 8a. The area that I have in mind floods completely in heavy rain storms and may hold water for 24-48 hours. I would prefer perennials over annuals.

Thank you. That information has been useful already.

Terry, a few other suggestions Deciduous hollies, fothergilla-great fall color, swamp sunflowers, Louisiana and Japanese irises, native honeysuckle and a lot of other natives that will do fine if there is plenty of sun. Some of my prettiest clumps of butterfly weed are near the edge of a pond that when it is real wet, they may be at the edge of the water for weeks or months. The amount of sunlight this area gets will make a huge difference on what works as well as how dry the spot can get in the summer if you can't water. For example, I have a spot that looks perfect for Joe-Pye and I have planted it at least 6-8 times and it does fine until we have a dry summer and then it is gone. I am just east of Birmingham so same conditions as you.
