You want a species or hybrid? I can only recommend the two on my wish list as I don't grow them myself (yet!). Caution as they both smell like poop, lol
B. echinolabium - who could resist foot-long flowers? Growers on the OB have said that they will do fine in phal light, perhaps a bit more.
B. Doggy Doo (echinolabium x orthoglossum) - I think this one is gorgeous! It brings the brighter colors of the orthoglossum to the long, slender petals of the echinolabium.
There are lots of other very interesting hybrids out there and they may be more robust, easier-to-grow plants.
Either way, let us know what you decide! I have to live vicariously through other bulbo growers until I can try some for myself!
