Plant Common Name
Dendrochilum Orchid, Golden Chain Dendrochilum
Dendrochilum magnum is a frost-tender evergreen orchid grown for its showy chain-like clusters of greenish-yellow flowers. It is native to humid upland forests in the Philippines, where it dwells on tree limbs and rock ledges.
The large, lance-shaped leaves of this epiphytic orchid are borne on clusters of conical to pear-shaped "pseudobulbs." Arching flower stalks arise in late summer and fall, each ending in a long, drooping, catkin-like spike of lightly fragrant, greenish-yellow flowers. Bloom may recur in spring. Individual pseudobulbs produce only one leaf and one inflorescence at a time.
This high-altitude tropical orchid needs bright indirect light ("high shade"), mild summers, and frost-free winters. Grow it in a coarse bark mix in a pot, or fix it to a a wood slab or tree branch. Water freely from spring to fall, and somewhat less in winter. Good air circulation and high humidity are essential. Deep green leaves are an indication that light levels are too low.
Use this evergreen orchid in the garden where hardy, or in a warm shaded greenhouse or conservatory. Place potted specimens on a pebble-filled water tray to boost humidity. Divide potbound plants in spring, if necessary. This orchid resents root disturbance.
