Rain garden planting

rainstorm prior to planting
We've got a small area of roof and a larger area of compacted lawn served by a created rain garden adjacent to our education building (at the South Carolina Botanical Garden).

Notice the stream of water entering off the pathway!

Our recent rain garden planting included a number of full-sun perennials that can tolerate periodic inundation, as well as droughty periods.

They're listed below, but my message, as the plant choice person, is that you need to know the conditions of your site, when choosing plants for a 'rain garden' which after all, is nothing more than a well-prepared perennial bed (and equivalent to a nice bit of natural vegetation/native plant community).
