Species Description
Bulbophyllum thaiorum, the “Thailand bulbophyllum,” is a miniature , warm- to cool-growing epiphytic species from Myanmar, Thailand, and Vietnam. It is grown mounted and should be kept moist in low light. Bulbo. thaiorum blooms in spring and produces beautiful umbels of red to yellow flowers (not sure which these guys are–plan for red and be happy for yellow). I first fell in love with the incredible dark, round pseudobulbs which are a great contrast to the green leaves and give visual interest to the plant all year. A stunning plant in and out of bloom.
Genus Description
Bulbophyllum is (currently) considered the most diverse genus of orchids with over 1500 species described. Bulbophyllums are found in all tropical areas on Earth, and they are as diverse morphologically as they are geographically. Though named for their bulbous leaves, all Bulbophyllums share some common flower characteristics including a hinged column which causes part of the flower to jiggle or bob. The better to lure in pollinators! Speaking of which, many bulbos are pollinated by flies–flies that are attracted to things that look and/or smell, um… dead. So approach bulbophyllum flowers with a cautious nose.
Growing Tips
Bulbophyllums are easy to grow. They like to stay moist, and most of them like intermediate to warm temperatures. We grow ours in intermediate (winter) to hot (summer) conditions. Similarly, they grow well in intermediate light although they can tolerate low light conditions, too (you may see fewer flowers). I have found increased success since growing mine in a closed tray with a little water standing in the bottom for those in pots. For plants in baskets, water frequently and from all sides. Bulbos enjoy regular fertilizer (I use a slow release and occasional additional fertilizer by spray), and may be potted in bark, moss, or a combination of the two. Because they have short roots, baskets or shallow pots work best for these guys.
