The largest species of staghorn fern, originated from the queen staghorn fern from Myanmar to Vietnam in Southeast Asia. They are also members of the Polypodiaceae family. The top will diverge, the short blades will rise, and they will sag when they grow to a sufficient length. The temperature in Hong Kong is very suitable for growth, and does not prefer direct sunlight. Water would only be needed only when the soil is dry, normally in about a week or so. The humidifying/ watering frequency would increase if it is placed in areas with conditioning.
