I have always been happy with plants from Orchids by Hausermann. Some are very tiny, in 2" / 5cm round pots. They always clearly indicate when plants are small. But sometimes plants are larger than expected.
Here are some Bulbos that were waiting for me this afternoon when I returned home from work:
Bulbophyllum cocoinum CH-23002 in a 3" / 7.5cm pot (There is a typo on their Web page. It is cocoinum, not laxiflorum.) This is a division.
Bulbophyllum laxiflorum CH-22343 in a 3.5" / 8.5cm pot. This is a division.
Bulbophyllum trigonosepalum x self CH-23068 in a 3.5" pot. This is a seedling.
