Ceratostylis philippinensis Rolfe ex Ames

Philippine Ceratostylis

Moderate careEpiphyteNon-toxic4–8 cm

A miniature epiphytic orchid from the montane forests of the Philippines, where it grows mounted on trees at elevations between 700 and 2,100 metres. It forms dense clumps of small, upright stems — each topped with a single terete (pencil-thin, cylindrical) leaf — and produces a succession of tiny, fragrant, snow-white flowers throughout the year, each barely a centimetre across. In cultivation it does best mounted on cork bark or grown in a mesh pot with long-fibre sphagnum, where its roots can breathe freely and stay evenly moist. It thrives in the steady humidity and gentle airflow of a terrarium or vivarium, making it one of the more rewarding miniature orchids for enclosed growing — provided air circulation is maintained.

Distribution

Propagation

Separate an established clump into large, many-stemmed divisions — each section should have several stems and a healthy root mass. This species resents root disturbance, so divide only when the mount or pot is clearly overcrowded, and repot or re-slab as infrequently as possible. Divisions establish best when kept in high humidity with steady warmth above 18 °C and minimal handling of the roots during the recovery period.
