Teratophyllum rotundifoliatum

Teratophyllum rotundifoliatum is a rare and visually striking fern native to the montane rainforests of Borneo, Sumatra, and Peninsular Malaysia. Belonging to the Dryopteridaceae family, it is renowned for its iridescent, translucent fronds that shimmer in low light, making it a favorite among fern enthusiasts and terrarium collectors.

Features:

• Fronds: The fern features delicate, bipinnate fronds with finely serrated edges. As it matures, the fronds elongate, and the edges become more pronounced, enhancing its ornamental appeal.

• Growth Habit: Teratophyllum rotundifoliatum is a slow-growing, creeping fern that thrives on moist substrates like sphagnum moss or hygrolon, often forming dense carpets in its native habitat.

• Iridescence: Under optimal conditions, the fronds exhibit a subtle iridescence, especially when grown in shaded environments, adding to its visual allure.

Care Tips:

• Light: Prefers low to medium indirect light. Direct sunlight can scorch its delicate fronds.

• Humidity: Requires high humidity levels, ideally above 70%. Regular misting or placement in a closed terrarium can help maintain the necessary moisture.

• Temperature: Thrives in warm temperatures, ranging from 20°C to 30°C (68°F to 86°F). Avoid exposure to temperatures below 15°C (59°F).

• Watering: Keep the substrate consistently moist but not waterlogged. Using distilled or rainwater is recommended to prevent mineral buildup.

• Substrate: Ideal substrates include sphagnum moss, hygrolon, or well-draining soil mixes rich in organic matter.
