100 Seeds Mud Plantain Alisma subcordatum Aquatic Native Pond Plant

Mud Plantain (Alisma subcordatum) is a native aquatic perennial prized for its rosettes of broad, ribbed green leaves and airy whorls of small white to pale pink flowers that rise on tall stalks in summer. It brings a clean, architectural look to water gardens, bog planters, and the shallow margins of ponds, where its foliage and seed heads add texture and movement through the season.
This species thrives at the water's edge, in consistently moist soil, or in shallow standing water up to a few inches deep, making it a natural choice for wildlife-friendly water features and rain gardens. Its seeds and cover appeal to waterfowl and small wildlife, while the tidy clumping habit keeps it easy to place along shorelines and in containers. Grow it as an ornamental accent in aquatic and wetland plantings.
