This came to me from Bill Thoms of bulbophyllums.com in October 2020.
In the background is my Ponderosa lemon tree, in flower now.
I set the 3 foot/1meter bare-root stick upright on the concrete slab in my sunroom, leaning against a window. It gets a good soaking by being sprayed with my mineral-laden tap water every morning before the sun hits it. Not many plants of any kind can tolerate that amount of heat and sun.
The flowers are about 3.5"/8.9cm across and 3.25"/8.25cm tall. They're supposed to be lightly fragrant. I haven't noticed that yet.
Unfortunately I just found out Bill has retired from orchid selling. His plants went to Krull-Smith, which does not have them listed yet. He still has his Bulbophyllums book available on bulbophyllums.com.
I highly recommend it to anybody wanting to grow Bulbophyllums.
