I ordered a flask of Mormodes rolfeana from LAOC. It's my 2nd flask. First was a Clowesia glaucoglossa, also from the same vendor, but I only have about half a dozen that survived so far, mostly due to neglect. Well with that under my belt, I'm a lot more confident this time around. Threw them into moss today in a covered plastic tray, and I think it should be okay like that for a few months, though I'll check periodically.
My personal recommendation for this vendor is to get the flasks. In my opinion most of their plants that they sell are tiny, maybe a year out of the flask. For 90 per flask, you get 25-30 seedlings. But if you buy their plants individually, he charges you 15-30 for a single plant.
The only exception to this is that I picked up a pretty decently sized Catasetum naso from them a while back.
LAOC has some pretty rare species from time to time, but considering how tiny they are, it's easy to accidentally kill them. Get the flask so that you could survive the purchase even if you kill a few. Most of my single plant purchases from this vendor have perished. I don't know whether to blame my inexperience with seedlings or the vendor. Probably both, since the auctions definitely make it appear as if you'd get a bigger plant. My
If I'm correct, LAOC is run by John Nelson and Tin-Wein Yu, the latter of which is the breeding expert, goes on trip to find rare species to sell. John seems to be responsible for the business and logistics side. I haven't had much luck getting info out of John. His responses to my email inquiries have been... terse. I feel like, to me at least, buying the flasks is the best way to take advantage of Tin-Wein Yu's findings without having to deal with whatever that's going on in the greenhouse operation.
