This one is much nicer than the previous Bulbophyllum lobbii (2013, 'Kathy's Gold'); I was particularly surprised at the size of the flowers.
I mean, the flowers weren't quite large enough to stretch across my hand, but it was close. I don't think I've ever seen a Bulbophyllum that big before.
Of course, the plant was pretty substantial, too. Maybe 'Sonoma Gold' is just an all-around giant?
