Starwort is an aquatic perennial best suited to ponds, slow streams, or water features where it can remain submerged or at the water's edge. It thrives in part shade and cool, clean water with minimal nutrient runoff. This plant is ideal for oxygenating small water gardens but requires monitoring to prevent overcrowding.
