I have an area of my property that lies low enough that when there is a heavy rainfall (happens
maybe 2 or 3 times a year) it floods to 2-4 inches deep and can take a couple-three days to drain
away. I'm wanting to plant shrubs/bushes in this area. Last year I planted some roses, butterfly
bushes, and a purple smoke tree. The roses and butterfly bushes survived all flooding events, but
the purple smoke tree died with the very first one.

What are some shrubs/bushes that are tolerant to short periods of flooding? Zone 7, full sun, red
clay soil.
