Phalaenopsis stuartiana

Species (Moth Orchid)

V Written by Editorial Team · Updated January 2026

Phalaenopsis stuartiana is a white moth orchid species with yellow and brown spotting on the lips and lateral sepals. Its leaves are attractively mottled, making the plant ornamental even when not in bloom. Native to Mindanao in the Philippines, it grows as an epiphyte in warm, humid forests. Plants produce heavily branched, arching sprays that can carry many long‑lasting flowers in winter to spring. Fragrance is usually faint. In North America it grows best indoors in bright, indirect light with warm temperatures and steady humidity.

Care in one minute

Grow in bright, indirect light and protect mottled leaves from harsh sun.

Maintain 65 to 85 °F (18 to 29 °C) with 40 to 60 percent humidity; provide airflow.

Fertilize lightly during growth; flush salts monthly.

Stake spikes early to direct the branching spray.
