Bulbophyllum medusae is an epiphytic orchid whose small, white-to-pale-yellow flowers cluster into a round head with long, thread-like sepals that trail outward like wild, windswept hair, a resemblance that inspired its name after the Gorgon of Greek mythology. Its pseudobulbs are compact, only about 2cm tall, while the leaves reach 15 to 20cm and the flower cluster grows to roughly 15cm across. Native to the warm, humid forests of Southeast Asia, it thrives in similarly warm, humid conditions and is generally considered suitable for growers with some prior orchid experience. As a perennial that spreads gradually along a creeping rhizome, it rewards patient care with a strikingly unusual bloom found in few other orchids.

About Medusa's Head Orchid
Bulbophyllum medusae is an epiphytic orchid from Southeast Asia known for its round clusters of thread-like flowers resembling wild hair. It thrives in warm, humid conditions and suits growers with some orchid experience.
7 things to know before growing Medusa's Head Orchid
1Bright, Indirect Light
Direct sun can scorch the leaves, so a bright spot with filtered light, like behind a sheer curtain, works well. Since this orchid comes from warm, humid parts of Southeast Asia, good air circulation is also important.
2Avoid Over- or Under-Watering
As an epiphyte, constantly soggy media can cause root rot, but this species also dislikes prolonged dryness given its preference for high humidity. Water thoroughly once the surface dries during active growth, and mist regularly to keep humidity up.
3Use a Well-Draining Epiphyte Mix
Bark or sphagnum moss with good airflow and drainage suits this epiphytic orchid best. It can also be mounted on a board or tree-fern fiber instead of potted.
4Repot as the Rhizome Spreads
Although the pseudobulbs stay small at about 2cm, the plant spreads outward as its rhizome grows. Once the rhizome reaches the edge of the pot, move it to a larger pot or fresh mounting material.
5Protect from Cold and Dryness in Winter
Coming from warm, humid Southeast Asia, this orchid should be kept somewhere warm indoors as temperatures drop, while avoiding excessive dryness. Watering can be reduced slightly during its slower growth period.
6Check the Rhizome and Leaves
When choosing a plant, look for firm leaves and healthy, undamaged pseudobulbs and rhizomes. Since it's a perennial that keeps growing along its rhizome for years, root and rhizome health are especially worth checking.
7Enjoy the Unusual Flower Cluster
The flower cluster grows to about 15cm, formed by small flowers with long, thread-like sepals gathered into a round shape. Look closely and you'll see the wild, hair-like form that inspired the plant's mythological name.
