Family

Orchidaceae

Botanical Name

DENDROCHILUM latifolium

Plant Common Name

Dendrochilum Orchid, Large-leaved Chain Orchid

General Description

This epiphytic orchid is grown for its long chain-like clusters of tiny yellow flowers. It is native to upland forests of the Philippines, where it grows on tree branches and rock ledges.

The broadly lance-shaped, light green leaves of this frost-tender orchid are borne on clusters of short narrowly conical "pseudobulbs," with each pseudobulb producing one leaf. A pendent, catkin-like spike of fragrant, greenish-yellow blooms is borne on an arching flower stalk in spring, and sometimes again in fall.

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.
