Microsorum thailandicum 'Blue Oil Fern'

Microsorum thailandicum, commonly known as the 'Blue Oil Fern', is a rare epiphytic/lithophytic fern native to Southeast Asia. This stunning fern produces thick, iridescent, teal coloured foliage that appears almost holographic under bright light. Extremely hard to come by and very rarely offered, these beauties are sure to sell out fast. 

CARE:
Requires a very bright position out of direct sunlight and sheltered from harsh weather conditions. Being an epiphyte/lithophyte, the Blue Oil fern requires a course potting mix. A suitable potting mix should generally consist of medium-course grade bark, perlite and/or coir chips. Water regularly, allowing the water to flow freely from the bottom of the pot (do not let sit in water). Fertilise with a half strength, general purpose fertiliser in spring to encourage growth.

Blue Oil Ferns are a rare find, as they are mainly propagated through division rather than tissue culture or spores. It's important to note that these ferns may occasionally display as green, due to various factors. The iridescent blue colour emerges when the plant is exposed to warm seasons with bright, indirect light. After shipping and during the winter months, the fern tends to exhibit more green tones. However, once it is placed in optimal lighting conditions during the warmer months, you can expect the iridescent blue to develop within 2 to 4 weeks. In winter, this transformation may take a bit longer.
