Care tips
It requires partial to full shade and consistently moist, organically rich, well-drained soil. Watering should be regular, especially during dry periods, avoiding the substrate to dry out completely. A common mistake is planting it in dry soil or full sun, which can lead to leaf scorch and poor growth. Protect from severe frosts in colder climates.
