Curled pondweed is a fully aquatic perennial best suited for garden ponds, water features, or slow-moving streams where it can remain submerged. It thrives in cool to temperate water with partial light and spreads quickly, so regular thinning is needed to prevent it from overtaking a water garden. It is not suitable for indoor aquariums or containers without adequate water volume.
