About Parkinson's Epidendrum

Epidendrum parkinsonianum · also called Parkinson's Epidendrum, Pendant Star Orchid · tropical

Epidendrum parkinsonianum is a dramatic pendant-growing epiphyte from Mexico and Central America with pendulous, fleshy, almost cylindrical leaves up to 46 cm long. Its large, intensely fragrant white flowers with a yellow-blotched lip are among the most spectacular in the genus. It demands very bright light, strong airflow, and must be mounted or hung to accommodate its drooping habit.

Preferred mix: Mounted on cork bark or tree-fern slab; or coarse bark in a hanging basket

Watch for — Shrivelled fleshy leaves: Dehydration of the thick, succulent-like leaves indicates underwatering or insufficient humidity for mounted plants. Increase watering frequency, mist the mount daily in warm weather, and check that the root system is healthy and not rotted.
