Dear Orchid Friends:

This month’s article showcases one of the jewels from Central American: Epidendrum parkinsonianum (AKA Coilostylis parkinsonianum). This orchid can be found from Mexico to Panama, and was in bloom during my recent Costa Rica trip.

Epi. Parkinsonianum grows in an intermediate climate at elevations 2000- 6000 ft (up to 1600m), however, this orchid can tolerate cool to warm environments with temperature ranges from 40F – 90F (22-27C).  I was at about 3000 ft. elevation when I saw these orchids. This orchid enjoys heavy rainfall and moisture, especially in the rainy season. The higher elevations will provide a covering of dew during the drier months. When growing your orchids, modify your watering so heavy watering occurs during its active growth season, which is generally spring to autumn.

Epi. Parkinsonianum is in the genus Epidendrum and is an epiphyte. The interesting characteristic of this orchid is the pendulous branches and inflorescences. These orchids do well mounted on cork or bark or in hanging baskets with great drainage. Give these plants room to hang freely. Pseudobulbs are terete shaped and clustered close together.

The pendulous inflorescences arise from short peduncles from the top of the terete pseudobulbs. The petals and sepals are long, narrow and a yellow-green color. The clear white lip is large with a yellow crest. The lip is 3 lobed – the side lobes almost resemble cheeks and the midlobe is slim, slender and pointed. Flowers are wonderfully fragrant – a citrusy aroma. Flowers are approximately 15 cm wide
(3-4”). Epi. Parkinsonianum generally blooms spring and summer, but can bloom at various time of the year.

Epi. Parkinsonianum can tolerate fairly bright light, so do give them ample light throughout the year.

I think Epi. Parkinsonianum is an eccentric looking species, but I do love it! I was delighted to catch this orchid in bloom. Pura vida!

Until next time,
