The slender sepals of small sized bulbophyllum are twisted together and hence the common name 'The Twisted Sepals Bulbophyllum'. The orchid (inclusive of the pseudobulb and leaf) measures about 4 - 5 cm high. The flower is carried above the leaf by a 10.5 cm long slender spike.
The plant's first spiking occurred November 2011, however the flower bud was bursted due to the extreme hot weather. In view of this, during the plant's second flowering in January 2012, I have tried to mist the orchid twice daily (once in the morning and evening) to increase the humidity at the planting area.
This time round, the flower have bloomed successfully.
I just found your blog and am hopeful you may have some advice for me. From your pictures, you are a very successful grower or have access to gorgeous ones. I have a Dancing Lady Oncidium. I am fairly new to orchid growing. The bulbs that the leaves grow from (pseudobulbs?) have shriveled. How did this happen and how do I correct it? The leaves are very healthy. I repotted it today and the roots seem fine (very little dried ones.) Thanks for your response, Kathy S., NJ. joyfulme2@hotmail.com
ReplyDeleteHi Kathy S,
DeleteIf the shrivelled pseudobulb is the old backbulb, then I think it's natural. However if the bulb is the recent new bulb, then perhaps you may want to increase the humidity at your growing area, by adding a layer of sphag moss as top dressing on top of your growing medium. Water when the medium is dry.
I hope my opinion helps. Thanks.
Bulbophyllum contortisepalum seems to be a continuous flowerer throughout the year. I have successfully bloomed them successfully from November 2011 till now.
ReplyDeleteThe red version seems to be more shy from flowering as compared to the yellow form.
Hi Vincent,
DeleteThanks for your comment. I only managed to flower successfully once. Glad to know that this yellow form of this species is a frequent bloomer. Red form is nice too.
