Care tips
This hybrid horsetail thrives in full to partial sun and prefers consistently moist environments, even with its roots submerged in shallow water. Keep the substrate constantly wet, never allowing it to dry out completely, making it ideal for pond edges or pots without drainage holes. Use a substrate rich in organic matter and clay, which retains moisture well, to mimic its natural habitat. A common mistake is planting it in dry soils or allowing the substrate to dry out, which can cause the stems to wilt.
