Native plants for rain gardens

A rain garden is a shallow basin planted to catch roof and driveway runoff and let it soak in over a day or two rather than run to the storm drain. That asks something unusual of a plant: tolerate periodic flooding *and* the dry spells between storms. These natives handle that swing. Put the wettest-tolerant species in the low center and grade out to ordinary garden plants at the rim.
