Beginner Gardening: Perennial for a wet area and afternoon sun, 1 by camsi

I'm looking for a flowering perennial that will bloom most of the year, but can thrive in a very moist area. I have a picture posted so you can see the area I need to fill in. I'm trying to fill in the rectangular area. I had ginger here, but the roots were so big and strong, I was afraid they would crack the patio concrete over time. This area tends to hold water. It's shady most of the morning, but gets afternoon sun. Any ideas?
