Care tips

It prefers full sun to partial shade and thrives in consistently moist soil or even shallow water. Watering should be abundant and frequent, ensuring the substrate never fully dries out. Use a substrate rich in organic matter with good moisture retention. A common mistake is allowing the soil to dry out, which can stress the plant and halt its growth.
