Other Orchid Events


To celebrate, we wanted to share with you a selection of our favorite orchids and orchid events:

Pacific Orchid Exposition

The Pacific Orchid Exposition, the largest orchid show in the United States, just celebrated its 64th year this past February. Event attendees viewed award-winning orchids and intricate displays while listening to live music and enjoying delicious food. Orchid growers from all over the world sold a wide variety of beautiful flowers, and orchid experts were available to educate show goers on the history of orchids and to help diagnose and treat orchid-growing problems. For more information about the Pacific Orchid Exposition and the San Francisco Orchid Society, visit the Pacific Orchid Expo page.

Angraecum Sesquipedale

The angraecum sesquipedale was the 64th Pacific Orchid Exposition’s show theme image. It is endemic to Madagascar and is commonly referred to as “Darwin’s Orchid” due to its association with Charles Darwin. Darwin predicted that the flower was pollinated by a then-undiscovered moth whose proboscis was of an unprecedented length. 21 years after Darwin’s death, the moth species with an incredibly long tongue was discovered and confirmed as the flower’s pollinator. A moth is pictured here pollinating an angraecum sesquipedale bloom.


This is an epiphytic orchid (one that grows harmlessly on other plants) which is native to tropical mountainous forests from Mexico to western South America.


Also known as the spider orchid, this orchid is mostly found in southern Australia. It is generally difficult to cultivate artificially outside of its native habitat


Laelia orchids are found in the subtropical or temperate climates of Central America, mostly in Mexico, preferring sunny, dry and cool conditions. This pictured laelia is a hybrid.


Dendrobium is a huge genus or orchids containing about 1,200 species. “The Brymer’s Dendrobium” pictured here  is a species of orchid native to Yunnan, Assam and northern Indochina.


These are commonly known as “lady’s slipper” orchids, native to southwestern Mexico, Central America, and tropical South America. They are notable for their large pouchlike lip which is curved inwards at the margins. This pictured phragmipedium is a hybrid.


Galeandra orchids enjoy moderately bright light, intermediate temperatures, and good humidity. They are identifiable by their bell-shaped flowers. The orchid pictured is a galendra batemanii, native to Oaxaca and Central America.
