Gardening in outdoor plant boxes with wet soil can be challenging, but choosing the right plants can transform soggy conditions into a thriving green oasis. Here are some of the best moisture-loving plants perfect for such environments:

1. Japanese Iris (Iris ensata) – Known for its stunning blooms, this plant thrives in consistently moist soil and adds vibrant color to your outdoor space.

2. Canna Lily (Canna spp.) – With its bold foliage and bright flowers, canna lilies are excellent for wet soil and bring a tropical vibe to plant boxes.

3. Marsh Marigold (Caltha palustris) – A cheerful, yellow-flowering perennial that loves wet conditions and attracts pollinators.

4. Cardinal Flower (Lobelia cardinalis) – This striking red-flowered plant thrives in damp soil and attracts hummingbirds, making it a garden favorite.

5. Sweet Flag (Acorus calamus) – A grass-like plant with aromatic leaves, ideal for adding texture to wet soil planters.

For optimal growth, ensure your plant boxes have adequate drainage to prevent waterlogging. Pair these plants with organic mulch to retain moisture and suppress weeds. By selecting water-tolerant species, you can create a lush, low-maintenance garden even in damp conditions. Happy planting!
