About Ludwigia bonariensis
Ludwigia bonariensis, commonly known as Water Primrose, is a perennial aquatic or marsh plant characterized by its reddish stems and small yellow flowers that emerge above the water surface. It's ideal for ponds, artificial wetlands, or as a marginal plant in water bodies, adding a touch of color and natural beauty. Its upright habit and prolonged flowering make it an attractive addition to aquatic environments.
Native range
South America, especially Argentina and Uruguay
Care tips
It requires full sun for abundant flowering, though it tolerates light partial shade. Keep the substrate consistently moist or submerged, as it is a wetland plant. It prefers nutrient-rich and slightly acidic soils but adapts to a variety of aquatic substrates. Avoid substrate dryness, as it can weaken the plant and reduce its flowering.
