Origin
Native to southern China and Vietnam, where it grows as a low understory plant in warm, humid forests.

Light
Prefers bright, indirect light. Tolerates medium light, but growth may become leggier and leaf markings less pronounced in lower light. Avoid strong direct sun, which can scorch the leaves.

Allow the top few centimetres of compost to dry out between waterings. Water more regularly during spring and summer, reducing frequency in autumn and winter. Avoid waterlogging.

Humidity
Enjoys moderate humidity but adapts well to average household conditions. Occasional misting or a pebble tray can be helpful in drier homes.

Use a free-draining houseplant compost with added perlite for airflow. Repot every 1–2 years in spring to refresh the soil and maintain a compact shape.

Food
Feed every 2–3 waters during the growing season with a balanced liquid houseplant fertiliser. Reduce feeding significantly in winter.

Temperature
Ideal temperature range is 18–24°C. Avoid cold draughts and temperatures below 12°C.

Pet-safe
Non-toxic. Safe for pets and children.

Sprouts Top Tips
