A Tropical State of Mind: What’s Blooming in the Smithsonian Gardens Orchid Collection

March 11, 2016 at 10:00 am Leave a comment

It’s March and it definitely feels like spring. This week’s blooming orchid selections are inspired by the tropical weather we’ve been having the past few days. Our species greenhouse has been looking rather tropical as well…

First on our list this week is Bulbophyllum saurocephalum, which is an epiphytic Philippine species. This odorless plant is also known as the Lizard Head Bulbophyllum because of the numerous tiny flowers that seem to be rearing their striped heads from the surface of the rachis.

 

Another drastically different Bulbophyllum that is blooming not far from B. saurocephalum is Bulbophyllum compressum. This is a hot growing Indonesian species found at lower elevations, with beautiful, ovate floral bracts of up to 30 delicate,white flowers.

I tend to gravitate towards the strangeness of Bulbophyllums, but I recognize that there are many other genera that are equally fascinating and worthy of mention. Below is the tiny flowered Tolumnia bahamensis.

Not only is this a fascinating North American species, it is highly appropriate to our tropical theme for this week. This species starts its life as a terrestrial in sandy soil, and as it matures, will send out growths that attach to taller plants, transitioning to an epiphytic habit.  Tolumnia bahamensis is only found in Atlantic coastal scrub habitats and is considered highly endangered. Atlanta Botanical Garden has been leading reintroduction efforts in Florida with much success.

To see part of the Smithsonian Gardens Orchid Collection on display, visit the Orchids In Focus exhibit at the United States Botanic Garden through April 27!
