Hi Janet
Attached are pictures of my Bulbophyllums that are flowering at the moment. These are all growing in a greenhouse with a minimum temperature of 15C.
Bulb. Wilbur Chang is a sequential flowering type. Last year it produced 17 flowers on one stem over about 3 months. Each flower lasts 5/6 days in good condition before fading. The scent is not for the fainthearted, not unpleasant when you first walk in the greenhouse but it certainly clears your sinuses if you smell it close up!
Andy has also sent over photos of the Masdevallias that are in bloom at the moment.
