Returns Simplified.Asplenium antiquum, commonly known as the Japanese Birds Nest Fern, is a graceful evergreen fern from the Aspleniaceae family. Native to East Asia, particularly Japan, Taiwan, and surrounding regions, this species is admired for its elegant rosette of glossy green fronds and its ability to bring a fresh, tropical touch to shaded interiors.
Unlike many finely divided ferns, Asplenium antiquum has broad, strap-like fronds that grow in a dense, upward-arching rosette, resembling a birds nest. The fronds are leathery, wavy-edged, and a deep, vibrant green, often reaching 5060 cm in length indoors, though in its native habitat it can grow larger. The frond bases converge into a central crown, giving the plant its birds nest appearance.
This fern has a clean, architectural form that makes it ideal for modern interiors. It is particularly popular as a houseplant because it is less fussy than some other ferns, provided its preference for consistent moisture and humidity is met.
Prefers bright, indirect light or partial shade. It tolerates lower light conditions better than many other houseplants, making it suitable for north-facing rooms. Avoid direct sun, which can scorch the fronds.
Keep the soil evenly moist but never soggy. Water when the surface feels slightly dry, using room-temperature water. Always water around the soil, not directly into the crown, to prevent crown rot.
Temperature: Thrives in 1624C. Protect from draughts and avoid prolonged cold below 10C.
Humidity: Requires moderate to high humidity. Mist fronds regularly, stand the pot on a pebble tray, or place in bathrooms or kitchens where humidity is naturally higher.
Plant in a peat-free, moisture-retentive but well-draining compost, such as a mix for ferns or houseplants. Repot every 23 years in spring, refreshing the soil while keeping the crown above the soil line.
Feed monthly in spring and summer with a diluted balanced liquid fertiliser. Do not overfeed, as excessive fertiliser can damage the fronds. No feeding is required in autumn and winter.
Remove old, yellow, or damaged fronds at the base to keep the plant tidy. Wipe the fronds occasionally with a damp cloth to remove dust and restore their natural shine.
A slow to moderate grower, typically reaching 5060 cm tall indoors. Over time, it forms a dense rosette of upward-arching fronds.
Crispy brown tips: Caused by low humidity or inconsistent watering.
Crown rot: Can develop if water is allowed to sit in the central rosette.
Pests: Rare, but may occasionally attract scale insects or mealybugs.
In its native environment, Asplenium antiquum grows as an epiphyte on rocks and trees in humid forests. Its elegant, glossy leaves and tolerance of lower light have made it a favourite indoor plant worldwide. It is often confused with Asplenium nidus (the true Birds Nest Fern), but A. antiquum is typically more upright and has narrower, slightly wavier fronds.
