The Tampa Orchid Club was thrilled to welcome back Naoki Kawamura for our September meeting, and he did not disappoint! His topic of choice? The fascinating Coryanthes, an orchid as intriguing as its Greek name, which means “flower like a helmet.” In his calm yet authoritative style, Naoki guided us through the peculiarities of this captivating genus, leaving us both entertained and enlightened.
Interesting Coryanthes Tidbits From Naoki
Naoki began by explaining the unique structure of Coryanthes blooms, particularly focusing on the "bucket" or lip of the flower. This bucket-shaped lip serves a critical function, as it collects dew and nectar, creating an irresistible trap for the male orchid bee. Drawn by the alluring scent, the bees enter the bucket only to find themselves stuck in the sticky nectar, with the slippery walls preventing an easy escape. As the bee struggles to get out, it slowly makes its way through a tiny opening near the bottom, getting coated in pollen along the way. It then flies off, only to repeat the process, unintentionally pollinating the next Coryanthes bloom. We all shared a chuckle when Naoki described these bees as “slow learners,” easily lured into the same trap again and again!
Naoki also treated us to a video showcasing a variety of Coryanthes species and hybrids. Many of us were amazed by the complexity of the flowers, particularly the intergeneric hybrids with Stanhopea wardii, which feature such intricate curves and twists that it's hard to tell the petals from the sepals. The vibrant spots and patterns on these hybrids were a show-stopper, and we were all captivated by the beauty of the short-lived blooms, which, although fleeting, are well worth the effort.
Tips For Growing Coryanthes
For those daring enough to try their hand at growing Coryanthes, Naoki shared some helpful tips. They require conditions similar to Stanhopea, with moderate light, good air movement, and a temperature range of 50º to 85ºF, ideally keeping things around 70º year-round. The key? Never let them dry out! A hanging basket is best, given the plant's pendant blooms, and Naoki recommended a medium mix of 1 part Orchiata, 1 part sponge rock, and 2 parts tree fern fiber. For those opting to pot them, Naoki's clever tip of adding styrofoam peanuts to half the container for better drainage was much appreciated.
Naoki did, however, leave us with a light-hearted warning: Coryanthes can be unpredictable. One moment they thrive, and the next, they may wither without warning. But, as with any orchid enthusiast, we know the thrill of the challenge is part of the fun!
Ready To Take On The Challenge
Thank you again, Naoki, for an incredible and educational presentation! We left the meeting with a newfound appreciation for these quirky orchids and, for some of us, perhaps a bit of inspiration to add Coryanthes to our collections—if we’re brave enough to take on the challenge.
