Microsorum thailandicum at a glance:
Microsorum thailandicum, often called Blue Oil Fern, is an epiphytic fern with narrow leathery fronds that show a metallic blue sheen rather than ordinary green. The colour shift is most noticeable in bright filtered light, where the surface can look almost lacquered, while the underside stays duller and more muted. It remains relatively compact, with fronds often reaching about 30 cm, and it suits mounted culture, airy fern mixes, or terrarium-style environments where humidity stays high.
Keep the substrate evenly moist but not waterlogged, maintain temperatures around 18–27 °C, and aim for humidity above 70% with good airflow. Because it is slow-growing and visually unusual even at a small size, it works best as a close-viewed collector fern rather than background greenery.

How to read these metrics
These metrics are standardised reference points. We compile them by reviewing and cross-checking multiple botanical and horticultural references, then refining them through real-world growing experience. Source links: Plant Care Resources.
Please use the values as guidance. Conditions vary by home, so the same plant can respond differently. For plant-specific context, read the full product description and browse our Plant Care Guides.
- Light: level + approximate lux at leaf level;
- Watering: “% dry” is the trigger before watering again; lower % stays more evenly moist.
- Potting mix: one-line profile (structure/drainage • moisture buffer • base • particle size).
- Temperature: “Ideal” comfort range; “Avoid below” marks higher stress risk.
- Humidity: target bands (Normal/Moist/Humid); consistency usually matters most.
- Growth habit: growth form (rosette, trailing, climbing) for placement and training.
- Support: needed/optional/none, whether stake, pole, or trellis improves structure and size.
- Growth speed: fast/average/slow under decent indoor conditions—expectations, not a promise.
- Max size indoors: realistic long-term potential; format differs for climbers vs. trailers.
- Toxicity & safety: chemical irritants/toxicity and physical hazards (spines, bristles).
- Origin & habitat: native region + typical biome/habitat as context.
