Water-Loving Plants for Rain Gardens
When you’re planning a New Orleans rain garden, you’ll want to select native aquatic plants like Louisiana iris and pickerelweed that can handle both standing water and the region’s intense summer heat.
Your perennial choices should include flood-tolerant species such as swamp sunflower and cardinal flower, which will thrive in the periodic inundations common to the Gulf Coast climate.
To manage seasonal water flow effectively, you’ll need to position these water-loving plants in graduated zones based on water depth, with deep-water species at the basin’s center and moisture-tolerant varieties along the garden’s higher edges.
Regular soil pH testing will help ensure your rain garden plants establish strong root systems in properly balanced growing conditions.
Choosing Native Aquatic Species
As southeast Louisiana’s climate becomes increasingly unpredictable, installing a rain garden with local aquatic species offers a smart solution for managing excess water.
You’ll find these native plants have adapted perfectly to our region’s subtropical conditions and frequent downpours.

These species naturally manage water flow while creating an authentic Louisiana landscape that connects you to our region’s rich ecological heritage.

Managing Seasonal Water Flow
Since New Orleans receives over 60 inches of rainfall annually, your rain garden’s success depends on strategic plant placement based on water flow patterns.
