Microsorum thailandicum, commonly known as the Blue Oil Fern or Thailand Blue Fern, is a distinctive tropical fern admired for its unusual blue-green to metallic-looking foliage. Its striking coloration and elegant leaf form give this collectible fern an almost iridescent appearance, making it a standout choice for tropical plant enthusiasts and collectors seeking unusual foliage plants.

Plant Characteristics

Microsorum thailandicum produces elongated, narrow fronds with a smooth to slightly leathery texture and a remarkable blue-green sheen that becomes especially noticeable under suitable lighting. The plant grows from creeping rhizomes and gradually develops into an attractive spreading specimen.

Its growth habit makes it suitable for pots, terrariums, greenhouse collections, or humid indoor growing environments. As the plant matures, its fronds can become longer and more prominent, although final size and coloration depend on growing conditions.

Care Guide

Provide bright, indirect light or filtered light while avoiding intense direct sunlight, which may damage the foliage. Keep the growing medium lightly and consistently moist, but never waterlogged.

This tropical fern appreciates high humidity, ideally around 60–80% or higher, combined with gentle air circulation. Maintain temperatures around 65–80°F and protect the plant from cold drafts and sudden temperature changes.

Use an airy, moisture-retentive yet well-draining medium containing materials such as coco fiber, fine orchid bark, sphagnum moss, and perlite. Avoid allowing the substrate to become completely dry for extended periods. Microsorum thailandicum is generally best suited to intermediate growers who can provide stable humidity and moisture.

Why Collectors Love It

Collectors appreciate Microsorum thailandicum for its unusual metallic blue-green foliage, elegant fronds, and exotic tropical appearance. Its distinctive coloration makes it especially appealing for collectors of unusual ferns and statement foliage plants.
