Care tips
This plant thrives in full sun to partial shade, requiring consistently moist or even waterlogged soils, making it ideal for waterside plantings. It prefers rich, organic, and well-drained substrates, though it toler tolerates a wide range of soils. Avoid allowing the substrate to dry out, as it is very sensitive to lack of water and its leaves can wilt rapidly. It readily propagates from seeds, often self-sowing in favorable conditions.
